Efficacy of Verimark and PQZ for reduction of cucurbit leaf crumple virus in squash in southern Georgia

Cucurbit Leaf Crumple Virus is transmitted by whiteflies and can decimate fall plantings of squash and other cucurbit crops in southern Georgia. While a few studies have shown insecticidal control of whiteflies can reduce virus incidence, this appears to be a rarity in southern Georgia where pest pressure is extreme in fall crops. We investigated the potential of two insecticides, Verimark and PQZ, for impacts on virus transmission under varying pest pressure by repetition the test across multiple planting dates. Results will be presented in the poster.
