The Q&A Archives: Pests on 2 year-old Pecan Tree

Question: I have some sort of pest affecting the newest growth on a 2-yeard sapling Pecan tree. It is sort of powdery and black. I tried a general fungus/pesticide spray but to no avail. Last year I trime the branches due to it's age and height. What suggestions do you have?

Answer: Without seeing the problem I can't really diagnose it and provide treatment suggestions. Since you know exactly what the problem looks like, you might want to visit the Texas A&M website ( that discusses insect and disease problems of pecan trees and has lots of photos.

Hope this helps you determine just what the problem might be. Good luck with your tree!
