ENEMIES. The most important enemy of the apple rust mite is the predatory mite. But whereas control of red spider mite is achieved very quickly with the predatory mite, in the case of the apple rust mite it often takes 1-2 years longer to reach a stable situation. 

Spraying with sulphur from the mouse-ear/greenbud stage onwards has a good suppressive effect on the apple rust mite. Spraying with sulphur is less effective once infestation is very severe, however.

Triphenyltin hydroxide (Fentin) and triphenyltin acetate (Brestan) are used to combat potato blight, leaf spot on celery and sugar beet, rice blast, and coffee leaf rust.
