New Insecticides for Apple and Pear IPM

Fujimite (fenpyroximate)- Fujimite belongs to the phenoxypyrazole class of insecticides. Its mode of action is as a mitochondrial electron transport inhibitor (METI), blocking cellular respiration (similar to Nexter and Kanemite). Practical resistance management would suggest that the use of METI miticides (either Nexter, Fujimite or Kanemite) be limited to one application/year.

Apple- Fujimite appears to be a good miticide alternative for the control of European red mites and twospotted spider mites in apple.

Pear- Fujimite appears to be a more active METI miticide than Nexter. Fujimite has a level of activity against both European red mite and twospotted spider mites. We do not have sufficient experience with the use of Fujimite against pear rust mite to comment on the potential to control this pest. Fujimite can be expected to control low to moderate populations of pear psylla.
