Project Information

Summary:

Problem and Justification: Urban farmers are unique among agriculturalists as they operate on a smaller scale in settings with less biological diversity and have less pest management options. Members of the project team have conducted more than 300 farm visits in Buffalo and NYC to date and observed that growers are challenged by pests that are not typically significant in rural NY settings, like Harlequin Bug, Two Spotted Spider Mite, and Whitefly.  While pests are universally problematic for all agricultural producers, challenges in urban areas are unique and include limited space, lack of scale appropriate IPM inputs, limited research, and historically minimal technical support from Extension and crop service providers.  

Solution and Approach: Our solution is to recruit 15 farms in Buffalo and NYC to participate in on-farm demonstration trials. These trials will educate growers on sustainable, non-spray options that are economically and environmentally sustainable while contributing to the social mission of the farms. Furthermore, they will simultaneously be used to evaluate the suitability of certain controls (exclusion, biological controls, varietal resistance, intercropping) in an urban setting. Farmers and project team members will identify site-specific pest management needs and sustainable solutions will be implemented and evaluated. Data and experiences will then be shared with other farmers through virtual and in-person events. Evaluation will document adoption and impact of sustainable techniques by farmers . 

There are urban farms located in every major city throughout NYS, and although educators have a clear idea of the predominate pests in Buffalo and NYC, urban farms in other cities may experience different pests or challenges in managing them. To assess the needs of the greater NYS urban agriculture community, an estimated 75 urban farms across NYS will be surveyed to assess their respective needs in pest management. The survey will focus on identifying the most challenging pests on urban farms, how pests are currently managed, and perceived benefits urban growers are getting from those practices. This data can in turn be used by Extension educators, crop service providers, and researchers to direct future research and education efforts.    

As part of the project, we will develop a guide on sustainable pest management practices for urban farms. Findings from the on-farm trials will be included, as well as a review on the different types of pest management practices (mechanical, biological, cultural, etc.), and additional resources that farmers can turn to for pest management help. To reduce barriers to accessing this knowledge, this guide will be translated into three foreign languages. This translated resource can greatly improve the ability for ESL or non-English speaking growers to succeed in their farming endeavors and thus increase the diversity of urban and rural farming in NYS and across the Northeast.  

 

 

 

 

Performance Target:

15 farmers in Buffalo and NYC will see an increase in revenue of $2000/acre as a result of implementing sustainable pest management practices for urban agriculture; and/or report quantifiable improved success in their social missions such as number of youths gaining pest management skills or diverse audiences reached. Increase in revenue will be the result of higher quality vegetables, improved yields, and decreased labor on pest management and sorting. This project will reach a diverse farmer base including minority and female farmers, new and beginning growers, and youth.

Introduction:

While there is no USDA Census data that reports on Urban Agriculture, urban farms are present in each of the 13 states in the NESARE region. In NYS alone, there are an estimated 75 urban farms. These farms may range in size from 0.25 to 2 acres. Urban farmers face unique challenges with pest production that are not extensively addressed through research or extension efforts. Urban soils have been heavily influenced by human activities such as construction, vehicular activity, or industrial activities and the status and health of urban soils influences the type of production urban growers engage in and how they manage pests.

Urban farms, unlike small rural farms,are surrounded by community gardens, home gardens, and school gardens. The concentration of these micro-production sites may increase the number and type of pests that urban farmers must battle. Close proximity to home gardens may increase the number of suitable host plants for insects and diseases and provide opportunities for pests to overwinter. Cities are often ports of entry and urban farms may be the first to be exposed to new, exotic pests. Urban communities are more demographically diverse than rural areas and urban farms often strive to grow culturally relevant foods for their neighborhoods. This may mean growing crops that are not typical for that climate and very little may be known about managing pests or diseases of these new crops. Urban centers are well known to be heat islands, in that the temperature of cities is often a few degrees warmer that surrounding areas due to the presence of impervious surfaces and buildings.

There are urban farms located in every major city throughout NYS, and although educators have a clear idea of the predominate pests in Buffalo and NYC, urban farms in other cities may experience different pests or challenges in managing them.  We anticipate a total of 15 farms across NYC and Buffalo will host demonstration trials that implement non-chemical pest management strategies such as host resistance, release of natural enemies/biological control, pest exclusion, intercropping or companion planting, to name a few. Farms will be recruited via the relationships that project members have already established with growers in NYC and Buffalo. The on-farm trials will provide growers the opportunity to observe the benefits of pest management practices first-hand.  On-farm workshops will be held to facilitate peer to peer learning. We anticipate hosting or participating in 3 workshops per year (9 total over project period). Workshops will be predominantly held in NYC or Buffalo, with 2-3workshops prioritized for another urban area, i.e. Syracuse, Rochester, Albany, Binghamton, etc. Workshops will be advertised on the Cornell Vegetable Program page, Harvest NY page, social media accounts, and in other relevant newsletters. The project team will adapt meetings to a virtual format if needed. Workshops will concentrate ontopics likepest identification, scouting, cultural, mechanical, and biological controls, creating beneficial habitat for natural enemies, etc. Farms in Buffalo and NYC that host pest management trials will serve as locations for workshops.

Research

Hypothesis:

This project has on-farm research in a demonstration function. We do not anticipate statistically valid experimental design. However, research activities organized by pest management practice trialed will be reported in this section.

Project Note: In the second year of this project (2022), there was a seven-month gap in project management due to personnel changes. This resulted in limited communication and impact measurement for on-farm demonstration trials in Buffalo. We are planning to conduct an urban farming scouting program in 2023 with farms in Buffalo and Rochester.

Materials and methods:

Releasing Ladybeetles to Manage Cabbage Whitefly

At Red Hook Farms and East New York Farms in NYC, we trialed Delphastus catalinae ladybeetles as a biocontrol for cabbage whitefly (Aleyrodes proletella), the most damaging pest of brassicas at both participating farms as well as many other farms and gardens in NYC. Delphastus is routinely used for control of other whitefly species in greenhouse settings, but we found no published research investigating Delphastus for control of cabbage whitefly.

At both farms, 150 to 300 Delphastus adults were released on 7/1/21 and 7/15/21 in selected locations within kale and collard plantings under a section of row cover which the farmers removed 7 to 12 days later. Whitefly infestation levels were estimated on a 0 to 3 rating scale at the time of release, where 0 = no whitefly nymphs or adults present on leaf undersides and 3 = severe infestation and unmarketable leaves; ratings were taken throughout the planting, averaging the values of 6 leaves sampled at each location. Using a hand lens, 3 leaves at each sampling location were briefly scouted for presence of Delphastus adults or larvae.

In 2022, we repeated the trial releasing Delphastus catalinae ladybeetles for control of cabbage whitefly (Aleyrodes prolotella) on the same farms.

Adjusting Soil pH to Manage Pillbugs

Several NYC urban farms reported pillbug (aka roly-poly, Armadillidium vulgare) damage on radishes and hakurei turnips in spring 2021, including Edgemere Farm, where marketability of spring radishes was reduced by at least 50%. The soils at all these locations were high in organic matter (>8% OM) with a pH of at least 7.0, in some cases above 7.5. Some research has suggested pillbug root-feeding activity increases with higher soil pH.

On 10/6/21, soil testing was done at Edgemere Farm on two rows which were to be planted into radishes and/or hakurei turnips in spring 2022. Elemental sulfur (to lower pH) was then applied to one of the rows at a rate of 1.5 lbs per 100 square feet. The other row was designated as a control with no sulfur added.

In spring 2022 before planting, elemental sulfur application was repeated on the test area at a rate of 1.5 lbs per 100 square feet. In June 2022, soil testing was repeated to measure soil pH and a pillbug damage assessment was conducted on radishes and turnips.

 

Taking a “Brassica Break” to Reduce Pest Pressure

Several of the most prominent pests of brassicas in NYC (cabbage whitefly, harlequin bug, and flea beetle) overwinter on brassica crops left standing throughout the winter for year-round harvest, a common practice of urban farms and gardens. Four farms participating in this project—and subsequently, at least three additional urban farms—implemented a period of at least two weeks with no brassicas present on the farm in winter or early spring of 2022; or, as we began calling it, a “brassica break.”

 

Releasing Biocontrols and Other Tactics to Manage Aphids

In 2021 and 2022, several farms in Buffalo reported aphids in high tunnels on tomatoes and cucumbers as a major pest.

Urban Fruits and Veggies (UFV) is an urban farm on the East Side of Buffalo growing on ¼ acre in raised beds and one high tunnel. They focus on mixed vegetable and herb production with plans to expand to hydroponic vegetable and fruit production at their second site. In 2021, UFV reported high aphid pressure on peppers and brassicas. Aphid populations quickly built up on pepper and brassica transplants in the high tunnel prior to planting outside. We recommended releasing biocontrols to bring the population below the economic threshold. Ladybeetles and lacewing larvae were purchased from Arbico Organics and released. In 2022 at UFV, we repeated releasing ladybeetles in the high tunnel for the control of aphids. Ladybeetles were released two times- once in July and once in August. They also tested using insect exclusion netting in the high tunnel and outside raised beds this year to help decrease pest pressure and support biocontrol release efforts.

The Brewster Street Farm with Journey's End Refugee Services offers the Green Shoots for New Americans Program which facilitates urban farming opportunities on Buffalo’s East Side. The farm grows numerous culturally important vegetables from farmer participants immigrating from Nepal, Afghanistan, Bhutan, and more. In 2022, aphids were noted to be present in the farm high tunnel before spring planting. After planting, the farm released lady beetles 2x in June and poured diatomaceous earth 1x on soil to manage aphid populations. In addition, we trialed releasing Aphidoletes aphidimyza gall midges two times (once in July and August) for additional control of aphids.

The Massachusetts Avenue Project (MAP) farm located on Buffalo's West Side runs a year-round youth employment program building youth leadership skills through farming and other civic engagement programs. In 2022, we trialed releasing Aphidoletes aphidimyza gall midges one time in the high tunnel for aphid control.

 

Using insect exclusion netting to manage cucumber beetles

Commons Roots Urban Farm is a one-acre urban farm in Buffalo producing diversified vegetables, fruit, flowers, and honey. In 2021, cucumber beetles were reported to be a significant pest on squash and cucumber. In 2021, we installed insect exclusion netting (ProtekNet Exclusion Netting, FIINTE3, 2x50-47 (Dubois Agrinovation)) on their caterpillar tunnel for exclusion of cucumber beetles on squash and cucumbers. Insect exclusion netting was applied prior to cucumber beetle emergence. Two Spotted Spider Mite (TSSM) damage was noted to be significant in the latter part of the 2021 season.

We were pleased to document during the 2022 growing season that Common Roots implemented insect exclusion netting on their caterpillar tunnel on their own to manage cucumber beetles on squash and cucumbers. Insect exclusion netting was applied prior to cucumber beetle emergence, and they grew parthenocarpic cucumber varieties. This adoption comes after an on-farm project demonstration in 2021. In addition, based off previous communication with project team members, Common Roots released a biocontrol mite predator, Phytoseiulus persimilis, one time early in the growing season to manage TSSM damage.

 

Swede Midge Management

An interesting development in this project was the severity of Swede Midge (SM), an invasive insect pest of brassicas, on Buffalo farms. This has been an educational opportunity and here we dedicate an update on Swede Midge Scouting and Management plans:

SM has caused so much damage to brassica crops at Common Roots that in 2021 these farmers removed broccoli, brussels sprouts, cauliflower from their crop line-up entirely. In 2021, they rotated their brassica crops as far from the previous year’s planting as possible and covered everything with Proteknet exclusion netting. The netting had to be removed from crops (collards, kale) because the plants were getting too tall for their hoop set-up. Moving forward, they continue to grow the less-preferred brassicas under exclusion netting. Collards and the Russian types of kale are in the more-preferred category. Winterbor kales are less-preferred. Farmers will continue to make sure that transplants going under netting should be free of worm pests, and ground should be free of brassicas for at least 3 years. 

The brassicas grown at UFV are primarily collards, kale, mustard greens, and kohlrabi. Collards have historically been the most effected by SM. In 2020, they moved all brassicas to a location outside of the city (Providence Farm Collective (East Aurora)) in order to get a marketable crop. In 2021, they brought collards back to the UFV site. Significant damage and larvae were observed early September 2021. In 2022, UFV focused on brassica crops in raised beds that have not have brassicas for past 2-3 years and used Proteknet exclusion netting.

Brewster Street Farm has had significant SM damage prior to this project and SM was observed in the late Fall 2021 brassica planting. Intercropping is a common practice at the farm. Intercropping is done to 1) maximize use of raised bed space; 2) for support of beneficial insects; and 3) to receive benefits from companion planting. However, intercropping makes crop rotation difficult when each raised bed may contain crops from different families. SM built up on brassica crops in numerous raised beds across the farm. To manage SM, we implemented an integrated approach – remove late season brassica crop residue and discard, and apply H. bacteriophora entomopathogenic nematodes to the soil to try to knock down the overwintering population. The entomopathogenic nematodes will feed on a diverse range of soil dwelling pests, including SM. Nematodes were applied twice- once in Fall 2021 and in Spring 2022. Nematodes were watered in with a pump sprayer to raised beds. Raised beds were pre-wetted to allow better survival and movement of nematodes through the soil profile.

5 Loaves Urban Farm is a farm ministry connected to the Buffalo Vineyards Church. They farm on 4 separate lots on the West Side of Buffalo. They grow a diversity of vegetables, fruits, herbs; they keep chickens and bees; and create numerous value-added products. The farm was noted to have SM damage on their brassicas in mid-summer 2021. Damage was quite extension on kale, collards, broccoli, and cauliflower. SM damage was found on 2/2 lots those brassicas were grown on. Brassicas are grown under row cover, but the fabric is torn in numerous areas. In mid-Summer 2021, we began monitoring the population of SM on the main lot. SM pheromone traps were collected on a biweekly basis for 2 months – 7/30, 8/12, 8/28, 9/8. We recommended rotating away from brassicas where possible and prioritizing brassicas on the most recently acquired lot. In addition, we recommended to cover with insect exclusion netting.

The above case studies of Swede Midge support potential further in-depth work on this pest in urban settings.

Research results and discussion:

Our work in this project is not pure research, as we are implementing natural pest management techniques that already have a demonstrated high potential for success. What is unique is the urban setting in which we adapt and deploy the management practices, as well as the site specific pests and practices. However, at some sites we are able to collect quantifiable data that provides a very applied research approach with the ultimate goal of demonstrating impacts to the farmers.

 Releasing Ladybeetles to Manage Cabbage Whitefly

Scouting on 7/15/21 and 8/18/21 showed slightly less whitefly pressure near areas of Delphastus release. On one farm, there was a rating of 1.5 near the release location versus 2 to 2.5 at the other locations sampled. At the other farm, there was a rating of 2 near the release location versus 2.5 at most other locations scouted. Three Delphastus larvae were identified on collard leaves at one farm on 9/23/21, including clear evidence of cabbage whitefly predation. The presence of Delphastus larvae and evidence of cabbage whitefly predation, along with lessons learned about improving effectiveness of releasing Delphastus in outdoor settings and farmers’ stated interest in this biocontrol as an IPM strategy, suggested that we should expand on this trial in 2022.

In 2022, we trialed releasing Delphastus catalinae ladybeetles again on the same farms for control of cabbage whitefly (Aleyrodes prolotella). As in 2021, we found Delphastus larvae on brassicas (evidence of successful reproduction, since Delphastus are released as adults), with clear signs of predation of cabbage whitefly nymphs. However, as in 2021, we did not find conclusive evidence of a corresponding reduction in whitefly damage. In 2023, we intend to attempt one more Delphastus release, this time with the release area remaining under row cover for at least 3 weeks, to determine whether a greater concentration of beetles will result in significant control.

An unanticipated finding in 2022: In the process of scouting for cabbage whitefly predation and Delphastus, we noticed the presence of a parasitoid wasp (Figure 1) which very clearly appears to be parasitizing cabbage whitefly nymphs; the adult wasps were very common in the scouted plantings, with as many as 10 per leaf. The wasp resembles Encarsia formosa, a commonly purchased biocontrol of greenhouse whitefly, but we believe this to be Encarsia tricolor, which we subsequently learned has been observed as a naturally occurring cabbage whitefly parasitoid in Eurasia. A search of academic databases has so far turned up no other documented observations of Encarsia tricolor parasitizing cabbage whitefly in the Americas.

Adjusting Soil pH to Manage Pillbugs

After the second sulfur application in spring 2022, the treatment area’s pH was measured at 6.8, compared to 7.2 for the control area. While pillbug damage was reduced in general compared to 2021 (Figure 2) (possibly due to drier weather), Edgemere found nearly no pillbug damage in the treatment area in 2022 (Figure 3), compared to 10-15% of radishes damaged in the control area (Figure 4). This early result shows promise in reducing pillbug feeding damage by reducing soil pH leading to increases in revenue by over $2000 per acre.

Taking a “Brassica Break” to Reduce Pest Pressure

In 2022, demonstration trials of a new approach to reduce brassica pest pressure was particularly successful. At all seven of farms implementing a brassica break, the first appearance of the previous years’ most significant spring brassica pests—cabbage whitefly, harlequin bug, or flea beetle—was delayed by two to seven weeks. This resulted in large increases in marketable product during brassica plantings’ head start. For example, at Kelly Street Garden, 163 lbs of collard greens were harvested before the first appearance of cabbage whitefly nymphs; the prior year, fewer than 35 lbs of collards were harvested before whitefly nymphs began affecting marketability. This 128 lb increase is over $350 more in revenue and amounts to over 23,000 lbs per acre and over $40,000 per acre in revenue.

Releasing Biocontrols and Other Tactics to Manage Aphids

With using an integrated pest management approach of releasing biocontrols and using insect exclusion netting in 2022, UFV reported increases in crop yields a with 25% increase in crop size, and an increase in crop quality and length of harvest window. UFV farm manager noted a reduction in labor time and costs. Prior to implementing these pest management practices, farm workers would spend 5 hours per week on pest management (observing, strategizing, handpicking) and after implementing these practices farm workers would spend 2 hours on pest management- net decrease of 3 hours per week. This equates to saving over $2200 on labor per year.

In 2022, the Brewster Street Farm manager noted the diatomaceous earth possibly had negative effect on lady beetles. The farm manager reported these practices resulted in an increase in crop quality and increased harvest window of high tunnel tomatoes by 4 weeks. The farm manager shared they “would have had to pull all tomato plants in July [2022] if not for the biocontrols.”

At the MAP Farm in 2022, no impact was observed from releasing biocontrols. This can partly be due to more communication needed from project members. Next year, we plan to work closer with this site and include them in our urban scouting program.

Using insect exclusion netting to manage cucumber beetles

At Common Roots Urban Farm in 2021, the insect netting appeared to provide sufficient protection of squash and cucumber plants from cucumber beetles. However, the cucumber plants did suffer from lack of pollination due to 1) not being a parthenocarpic variety and 2) the exclusion netting further inhibited pollinators from entering the tunnel. To remedy this, Common Roots moved frames of bees into the tunnel. Pollination thereafter seemed adequate but noticeably less. Two Spotted Spider Mite (TSSM) damage was noted to be significant in the latter part of the season.

In 2022, Common Roots reported the insect netting appeared to provide sufficient protection of squash and cucumber plants from cucumber beetles. After releasing the biocontrol mite predator, farmers reported they noticed a decrease in TSSM damage and would have released the biocontrol a few more times but cost was prohibitive. Overall, Common Roots reported a 25% increase in cucumber yield in 2022. Prior to this project and implementing these sustainable pest management strategies, Common Roots reported $323 in cucumber revenue. In the second year of this project and after implementing these sustainable pest management strategies, Common Roots reported $1070 in cucumber revenue, a $747 increase in cucumber revenue over the course of this project.

Next year in 2023, Common Roots is planning to repeat trialing insect exclusion netting and planting parthenocarpic cucumber varieties. We plan to scout for TSSM early and get ahead of it by releasing a mixture of a specialist mite predator, Phytoseiulus persimilis, and generalist mite predator such as Amblyseius cucumeris, Stethorus punctillum or Neoseiulus californicus.

Swede Midge Management

In 2021, Swede Midge (SM) was identified as a priority pest on Buffalo farms. In 2022, a few farms implemented recommended SM management strategies. In 2022, UFV reported practicing crop rotation focusing brassica crops in raised beds that have not have brassicas in them for past 2-3 years and used Proteknet exclusion netting. They did not notice significant swede midge damage this year.

At Brewster Street Farm, all raised beds affected by SM in the first year of this project had late season brassica crop residue removed and discarded. These beds were treated with Heterorhabditis bacteriophora nematodes in Fall 2021 and Spring 2022. In 2022, SM was still present on farm but less damage was observed compared to last year.

Participation Summary
5 Farmers participating in research

Education

Educational approach:

On-farm Demonstration Trials:  We anticipate a total of 15 farms across NYC and Buffalo will host demonstration trials that implement non-chemical pest management strategies such as host resistance, release of natural enemies/biological control, pest exclusion, intercropping or companion planting, to name a few. Farms will be recruited via the relationships that project members have already established with growers in NYC and Buffalo. The on-farm trials will provide growers the opportunity to observe the benefits of pest management practices first-hand.  

Workshops: On-farm workshops will be held to facilitate peer to peer learning. We anticipate hosting or participating in 3 workshops per year (9 total over project period). Workshops will be predominantly held in NYC or Buffalo, with 2-3 workshops prioritized for another urban area, i.e. Syracuse, Rochester, Albany, Binghamton, etc. Workshops will be advertised on the Cornell Vegetable Program page, Harvest NY page, social media accounts, and in other relevant newsletters. The project team will adapt meetings to a virtual format if needed.  Workshops will concentrate on topics like pest identification, scouting, cultural, mechanical, and biological controls, creating beneficial habitat for natural enemies, etc. Farms in Buffalo and NYC that host pest management trials will serve as locations for workshops. We estimate 10 farmers will attend each meeting. The project team will maintain a list of growers that attend workshops, and provide technical assistance to growers via email, phone call, or in-person visits, and/or through regular scouting.  Results will be made available to organizers of winter educational events (virtual or otherwise) such as the NOFA-NY Winter Conference, the NYC Urban Agriculture Symposium, or the Urban Food Systems Symposium.  

 

Rural Farm Tours: The project team will host a series of rural vegetable farm tours in order to expose urban growers to rural vegetable production, pest management on a larger scale in both organic and conventional settings, scouting, common equipment used to manage pests, and preferred management practices. Shared learning on common issues creates community building opportunities between urban and rural farmers, who may be separated not only by geography, but also cultural and racial differences. 

 

A ‘Sustainable Pest Management Guide for NE Urban Agriculture’ will be created as part of this project. Cities, including Buffalo and NYC are home to a large proportion of immigrants and refugees. In Buffalo Public Schools more than 83 languages are spoken, such as Spanish, Arabic, Karen, and Somali. To reduce barriers to accessing this knowledge, our guide will be translated into three foreign languages to-be-determined by engaged farmers. 

 

All growers that participate in workshops held during the duration of the project will receive a virtual or paper copy of the UA sustainable pest management manual once completed. The manual will be made available online as a pdf for download.  

 

Farm Visits: The project team will conduct 100 visits with urban farmers across NYS per year over the course of the project, totaling 300 by the end of the project.

Status:
In Progress
Accomplishments:

In the first year of the project, progress toward this milestone included the recruitment of 3 farms in Buffalo and 2 in New York City to implement on-farm sustainable pest management trials including as crop rotation, pest exclusion and the release of beneficial insects. In Buffalo, Swede Midge and Striped Cucumber Beetle were identified by growers as priority pests. In New York City, Two Spotted Spider Mite and Cabbage Whitefly were major pests. Cabbage Whitefly in particular is of note as it is not a common pest in the Northeast, yet was the most prevalent pest on some NYC farms.

In the second year of the project, progress towards this milestone included the recruitment of two returning and four new farms in New York City and three returning and one new farm in Buffalo to implement on-farm sustainable pest management trials. In New York City, brassica pests including cabbage whitefly were identified as major pests, as well as pillbugs. Management tactics trialed this year included crop rotation, releasing biocontrols, and reducing soil pH. In Buffalo, aphids, Swede Midge and Cucumber Beetles were again identified by growers as priority pests. Management tactics trialed this year included releasing biocontrols, crop rotation, and using insect exclusion netting.

 

Milestone #2 (click to expand/collapse)
What beneficiaries do and learn:

2) Urban farms across cities in NYS (Albany, Rochester, Buffalo, Troy, Binghamton, Syracuse, NYC, etc.) complete survey on the predominate pest issues, preferred pest management practices, perceived benefits, resources and information needed, etc. Activity: Project members craft survey and submit to 75 urban farms across NYS.

Proposed number of farmer beneficiaries who will participate:
50
Actual number of farmer beneficiaries who participated:
17
Proposed Completion Date:

Accomplishments:

A survey has been created in print and online form. It has been distributed on four relevant program websites, two newsletters, two list servs and over five social media accounts estimating to reach over 4100 people. Project team members have had success asking farmers survey questions directly and recording responses. This has led to informative conversations helping to shape the direction of this project. At this time, 17 farmers have responded to the survey.

Our original proposed completion date was 3/1/2022 and this was not met due to team personnel changes. We now aim to achieve this milestone by 12/31/23.

Milestone #3 (click to expand/collapse)
What beneficiaries do and learn:

3) Urban farmers/managers/youth interns are exposed to rural vegetable production and pest management. They learn about the predominate pests in rural settings. Rural farmers learn from urban growers about their challenges in managing pests and provide advice on how pest controls could be adapted to urban settings. Activity: Urban farmers tour rural vegetable farms outside Western NY or NYC.

Proposed number of farmer beneficiaries who will participate:

Accomplishments:

Four different events were held in 2021, 3 virtual and 1 in-person.  A total of 87 individuals were reached through these events.  The curriculum for these events was largely focused on beneficial insects; how to attract, rear, create habitat for them. The pests of concern were aphids, Two Spotted Spider Mite and Cabbage Whitefly.

Nine different events were held in 2022, 4 virtual and 5 in-person reaching a total of 151 individuals. Workshops covered topics including scouting and pest identification, understanding life cycles of important pests and how to manage them, understanding beneficial insects, and using organic and biopesticides. Three workshops were targeted specifically towards youth, with a focus on insects on the farm, building healthy soils, and cultivating healthy land and community.

To date, there have been 13 events for a total of 20 program hours and reaching 238 individuals.

Learning Outcomes

11 Farmers reported changes in knowledge, attitudes, skills and/or awareness as a result of their participation
Key areas in which farmers reported changes in knowledge, attitude, skills and/or awareness:

Urban Fruits and Veggies (UFV) is an urban farm on the East Side of Buffalo growing on ¼ acre in raised beds and one high tunnel. They focus on mixed vegetable and herb production with plans to expand to hydroponic vegetable and fruit production at their second site. Over the course of this project, UFV has trialed releasing biocontrols to manage aphids, and using insect exclusion netting to help decrease pest pressure in general and support biocontrol release efforts.

Through interviews and surveys, the UFV farm manager reported that these integrated pest management practices “fit in well with the mission of our farm. [On the farm], we try not to use chemicals and grow food with our community in mind.” The UFV president added “We serve underserved communities- traditionally there has been a lack of care when working with underserved communities. [When producing food], we always have the community in mind, we want to provide them with better quality, increased variety, and nutrient dense crops. This way of growing cost more and is more labor intensive, but we feel our community is worth it.” The UFV education programs include sustainable pest management content and the farm is planning to reach over 100 participants -a mix of youth and adults- in the next year.

The Brewster Street Farm with Journey's End Refugee Services offers the Green Shoots for New Americans Program which facilitates urban farming opportunities on Buffalo’s East Side. The farm grows numerous culturally important vegetables from farmer participants immigrating from Nepal, Afghanistan, Bhutan, and more. Over the course of this project, Brewster St has trial releasing biocontrols to manage aphids and Swede Midge.

Through interviews and surveys, the Brewster Street Farm manager reported that these pest management practices “fit in well with the farm and are a good lesson for our farmers.” Early in the growing season, the farm manager worked with farmer participants in the Green Shoots for New Americans Refugee Agricultural Program to identify aphids and remove them from plants by hand. In addition, they introduced concepts of beneficial insects. By the end of the season, the farm manager reported “Now if [farmer participants] see a ladybug, they move it to a plant with aphids.”
