Project Information

Summary:

Note to readers attached is the complete final report for FNE00-300.

Important lessons were learned from the first part of this on-farm research in 1999 to control an outbreak of grape leaf-hoppers in this Finger Lakes vineyard, without resorting to chemical insecticides. The core of last year's effort was a repeated application of the botanicals pyrethrum and rotenone along with an insecticidal soap. The result was encouraging but inadequate; leaf feeding by the insects was still too damaging by the end of the season, reducing grape sugar levels and weakening the vines. It was decided that the sprays were started too late in the season.
