Common Name

Cucurbits yellow stunting disorder virus and CYSDV

Potential Hosts

Cucumber, pumpkin, zucchini, bitter gourd, squash, watermelon, and melon

Who am I?

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.

Control measures

There are no treatments for viruses. Infected cucurbits plants cannot be cured; therefore, the focus should be on prevention.

Cultural

*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.

Conventional (chemical)

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.

Organic

Azadirachtin, Fatty acid potassium SAL, Beauveria bassiana strain GHA, neem oil, and other plant oils

Biological

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.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
