Miticide options for controlling mites in fruit

Mites can be significant pests of fruit crops. There are many miticides available for control of European red mites (ERM), twospotted spider mites (TSSM), cyclamen mites (CM) and rust mites (RM), as well as apple and pear rust mites, pear blister mites, plum nursery mites and blueberry bud mites. However, according to Michigan State University Extension, their performance characteristics are not all alike.

The following table is designed to summarize several key variables that can help you determine which miticides are optimal for your integrated pest management program.
