Bean Golden Mosaic Virus
Class: Viruses
Common Name
Bean golden mosaic virus and BGMV
Potential Hosts
Beans
Who am I?
BGMV is of the genera begomovirus of the Geminiviridae family. BGMV is transmitted by whiteflies (bemisia tabaci) after they feed on infected plants and introduce the virus to adjacent plants. It is common around the world in bean growing regions. Infected bean plants will exhibit yellowing, downward curling and deformation of leaves, and a yield reduction.
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.
*Sanitation: Remove weeds. Several kinds of weeds can act as hosts that allow the virus to remain present between seasons. It can contaminate crops in the following season and make the virus control difficult.
*Use pest monitoring techniques such as yellow sticky traps to aid in keeping track of the whitefly population.
Conventional (chemical)
Preventing and stopping the spread of BGMV is done by focusing on controlling whiteflies, which can be difficult since a whitefly population can quickly develop a resistance to conventional chemical treatments.
The following insecticides are 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.
