    Proposal abstract:

    The purpose of this project is to determine appropriate varieties of winter squash for organic production in the Southeast by evaluating disease resistance, insect damage susceptibility, yield, sugar content, and storage longevity. The hot, humid summers in Georgia result in higher disease and insect pressure but varietal resistance in squash is limited, especially in desirable varieties. Organic systems research is needed to evaluate squash varieties for resistance or tolerance to an array of disease and insect pest problems, as well as adaption to the Georgia climate.

    Project objectives from proposal:

    • Evaluation of varieties of squash for disease resistance, yield, fruit quality, and insect pest feeding preference.
    • Development of a squash bug inoculation method to introduce potential biocontrol organisms into squash.
