Stem borers

There are several reports on stem borer damage in Jatropha. However, it looks like it only occurs on heavy soils and most of the time there is a lot of ant activity as well. This is a strong indication that growth conditions are not optimal. Older plants usualy survive the disease, but younger plants may break trough wind or mechanical damage. (picking)

Chemical control has been reported. (Carbofuran)

(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)
