(Not known by any other names)

SUMMARY

Cyclaniliprole is an insecticide for fruit, greenhouse and some other crops. It has a low aqueous solubility and is non-volatile. It may be environmentally persistent. It has a high to moderate toxicity to most aquatic species, is highly toxic to bees and moderately toxic to earthworms. Cyclanilliprole has a low oral mammalian toxicity.
