I have 6 citrus trees in my yard and all of them have the same problem.
The leaves are curling and turning pale green. They also have brown trails running through the leaves. I cannot find any insect anywhere on the trees.Can someone help me?
This site has a list of various citrus problems, and how to treat them: https://edis.ifas.ufl.edu/TOPIC_Citrus_Pests_Diseases I cannot know for shure exacly what it is now, so try to get some pictures of the leafs posted here. But to me it sounds like a fungi problem, so maybe try and spray it with some non copper baised fungicide, or use a systemic fungicide.
Organocide has been the most effective I've tried so far..but I'm still looking for a product that I'd like enough to recommend it.
You will need to research which product is best for you. There is a product by bonide, another that is some type of oil, and many other pesticides that claim to eliminate or control leaf miners. Each product usually has a list of pests treated on the back of the label.
