White powdery fungus mainly on younger leaves and stems. Most Jatropha,s get this disease in area's with  low  temperatures, especially during night time when relative  humidity is high.

Brrrrrrrr, cold outside

Treat with products based on dithiocarbamate (Zineb, Dithane, Manzate etc.)

(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)
