Description: Field day handout presented at North West Michigan Tree Fruit Research and Extension Center annual field day. Handout presents outcomes from 2021 field project and initial findings from 2022 field project. Projects measured the development of spotted-wing drosophila on waste cherry piles in NW Michigan orchards that were either left alone, treated with poultry manure or crushed. In 2022 a Urea treatment was added. Projects indicate that both crushing and mixing with poultry manure at 15% or 25% by volume nearly eliminated SWD reproduction and also reduced sap beetle presence in piles.
