Performance

1. Low toxicity to higher animals, low toxicity to fish, birds and bees, and safe to natural enemies of spider mites.

3. It has a good effect on nymphs and does not kill adult mites. However, after the female adult mites are exposed to the medicine, the amount of eggs laid is reduced, and the resulting infertility or the eggs do not hatch.
