Anybody know what's causing my limon agrio (Citrus limon) leaves to buckle and curl like this? I know that a bit of curl is normal, but this really looks like some kind of pest damage.... Any help would be appreciated!
I can't see the trails, but it is probably the asian citrus leaf miner. It burrows under the surface of the leaf and lthe rolls the edge of the leaf to make a cocoon. They are only 2-3 mm long, but infestations can get pretty heavy. There are 2 things that will help-- horticultural oil (spray in the evenings after the temp drops below 85), or spinosad. The horticultural oil does not kill the miners but keeps the adult moth from laying eggs on oily leaves. Spinosad will kill the larvae, but it does not last long. Skeet
