Who Am I?

Cacao swollen shoot virus is primarily transmitted by different species of mealybugs that feed on the sap of cacao trees.

Female adult mealybugs can crawl across branches of overlapping trees and spread the virus. Although, even relatively distant trees are in danger of infection; ants are attracted to honeydew secretions produced by feeding mealybug and can move the mealybugs great distances. Once infected, trees are usually killed within several years.

Symptoms are diverse and will vary from one cacao variety to another. They can include discoloration of foliage, reddening of young leaf veins, chlorosis, small distorted pods, swelling of stems, and die back.

Control Measures

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.

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

sulfoxaflore, spirotétramat, buprofezine, extrait de chenopodium, chlorpyrifos, imidaclopride, thiaméthoxame, acétamipride, et thiachlopride.

huile de neem, huile d’arbre à thé, huile minérale, and détergents (savon industriel) spécialement conçu pour un usage agricole.

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.
