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)

 

Leaf miners seldom come alone. They occur on the mature leaves of Jatropha plants mostly attacked by other pests like mealy bugs .

 

The larva's feed on the leaves, making mines that later on dry and form brown spots on the leaves.
