CYSDV is a viral disease transmitted by whiteflies (Bemisia tabaci). CYSDV causes significant damage to cucurbits crops around the world and causes up to a 50% reduction in yields depending on the cucurbits species. After the vector introduces the disease to a healthy plant, within a short time yellow areas between veins (interveinal chlorosis) appear on older leaves.
There are no treatments for viruses. Infected cucurbits plants cannot be cured; therefore, the focus should be on prevention.
*Use plant varieties and seeds that are resistant to the virus.
*Grow Inside Structures: Keep the structure closed and the nets free of holes.
*Use pests monitoring techniques such as yellow sticky traps to aid in keeping track of the whitefly population.
Preventing and stopping a CYSDV infection from spreading is done by focusing on eliminating a whitefly infestation. This can be difficult since whitefly populations quickly develop a resistance to conventional chemical treatments.
The following are insecticides used in one or more parts of the world: cypermethrin, deltamethrin, bifenthrin, diafenthiuron, thiamethoxam, imidacloprid, acetamiprid, spiromesifen, buprofezin, cyantraniliprole, spirotetramat, and synthetic terpenes extract of chenopodium.
Azadirachtin, Fatty acid potassium SAL, Beauveria bassiana strain GHA, neem oil, and other plant oils
Amblyseius swirskii is a commercially available predatory mite that is capable of significantly controlling a whitefly population.
Try to avoid frequent use of organophosphate, carbamates, or pyrethroids insecticides; they will eliminate natural whitefly enemies and pollinators.
*Names marked in red are considered to be highly poisonous to beneficial insects.
*Names marked in green are considered to be organic and IPM (integrated pest management) compatible.
