Milt from San Tan Valley, Arizona writes
I noticed clusters of a very small black insect on the new growth on my orange tree and am concerned that whatever they are could damage the tree. I also have a grapefruit tree that is showing brown patches on many of the leaves.
We recommend Bonide Citrus, Fruit, and Nut Orchard Spray. This will treat for both insects and disease using all natural ingredients.
