Spider mites -Polyphagotarsonemus latus

mainly active in nurseries and young plantations worldwide


Young plants get very thick , leathery leaves with veins almost on top of the leaf service. Growing points will dry and the plant stops growing until a new flush starts, provoked by rain or irrigation. It is a very common and typical disease of nursery plants and recently planted plantations. The plant often re growths with a bunch of flowers in the top, resulting in the ideal easy to pick Jatropha fruits. If we could control this disease or creating the same effect in other ways, it would be an ideal instrument for plantations with mechanical harvesting.


If single plants are being attacked, cut the infested part and burn it. If the attack is minimal, wait till pruning time and cut all the attacked plant parts.

Larger area's can be treated with: Avermectin1.9EC@0.5ml/l, Dicofol 18.5EC@3ml/l, Polo @ 0.5ml/l, or any common mitecides


NOTE: THE USE OF ANY RECOMMENDED TREATMENT ON THIS PAGE IS ON USERS OWN RISK AND SHOULD BE ALLOWED FOLLOWING LOCAL LAW AND REGISTRATION. (Actually this is a big problem, since no pest- or fungicides are being specifically registered  for Jatropha. Jatropha as a crop is simply too new and only recently got the interest from pesticide manufacturers)
