Who Am I?

Cucumber mosaic virus, from the cucumovirus genus, is common worldwide in both temperate and tropical climates, but cannot survive in extremely dry conditions. Infection results in severe damage to host plants. The symptoms induced by CMV includes light green–dark green mosaics, generalized chlorosis, stunting, leaf filiformism, and local chlorotic and are host specific.

CMV is transmitted by Aphids and parasitic weeds. In lab conditions, the virus can be transmitted mechanically through plant sap and is seedborne. The large number of CMV hosts allows it to overseason from one crop to another by potentially surviving in plant roots.

Control Measures

Il n’y a pas de traitement contre les virus. Les plantes infectées ne peuvent être guéries; par conséquent, l’accent devrait être mis sur la prévention des épidémies de virus. Si seules quelques plantes sont infectées, elles doivent être retirées du champ.

Calendrier: Il est plus facile et plus rentable de surmonter les infestations au cours des premières étapes. Sur une base hebdomadaire, surveillez le terrain et recherchez les insectes porteurs de la maladie.

Assainissement: Gardez l’environnement proche des cultures en éliminant les mauvaises herbes, les débris de plantes, les parties endommagées, la croissance indésirable des plantes et les plantes à proximité qui ne sont ni cultivées ni protégées.

Grandir à l’intérieur des structures : Gardez la structure fermée et les filets exempts de trous.

Les produits utilisés dans une ou plusieurs régions du monde peuvent contenir les ingrédients suivants :

Flonicamid, pymétrozine, sulfoxaflore, imidaclopride, thiaméthoxame, acétamipride, bifenthrine, cyperméthrine, et chlorpyrifos.

azadirachtine, huile de neem, pyréthrines, et sel de potassium d’acides gras.

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.
