Insecticide rotation is key in long-term management of whiteflies. Whiteflies can transmit cucurbit leaf crumple virus and cucurbit yellow stunting disorder virus.
Rainfall is needed to, not only help the crops grow, but knock back some of the whitefly populations.
Presence of Powdery Mildew a Concern for Southeast Vegetable Growers andHigh Whitefly Pressure Reported in Florida Vegetables.
“Whiteflies cause feeding injury issues in vegetables and transmit two viruses: cucurbit leaf crumple virus and cucurbit yellow stunting disorder virus. Vegetables like squash, zucchini, cucumber, cantaloupe and snap beans are highly susceptible to these viruses. Commercial cultivars that have resistance or tolerance to these pathogens are not available.”
Researchers will focus specifically on vegetable systems and find long-term sustainable solutions to manage whiteflies and whitefly-transmitted virus complexes. There are three whitefly-transmitted viral pathogens, which are known to reduce the quality of vegetable crops, specifically cucurbits: cucurbit leaf crumple virus, cucurbit yellow stunting disorder virus and sida golden mosaic virus.
