    Proposal summary:

    Elizabeth and Peter Ryan test the use of a single thinning application of carbaryl shortly after petal fall as an alternative control strategy for leaf hoppers. Preliminary trials at the New York State Agricultural Experiment Station suggest this strategy can significantly reduce egg laying adults and second generation nymphs, thus reducing the need for additional pesticide applications later in the season.
