Activity
Insecticide
Acequinocyl is active against all mite life stages, especially motile forms. It has activity against strains resistant to established acaricides. The product is primarily a contact acaricide; acequinocyl is not systemic and can act secondarily by oral uptake. It has a long residual activity, lasting 30-40 days at field rates.

Mode of action studies on the housefly confirmed that acequinocyl is not responsible for the observed inhibition of electron transport at Complex III in mitochondria; the activity is due to the formation, by hydrolysis, of the deacetylated metabolite (2-hydroxy-3-dodecyl-1,4-naphthaquinone, DHN).

Official efficacy trials in Japan show the miticide to have an excellent efficacy and crop safety and no development of miticide resistance were detected. Thorough foliar coverage and early application, when threshold populations are observed, are required for optimal activity.

Fate in :
Acequinocyl is a selective miticide with no ecological risks for the following beneficial terrestrial species: parasitoid wasp (Hymenoptera; Braconidae), lacewing (Neuroptera; Chrysopidae), honey bee (Hymenoptera; Apidae), spider (Araneae; Lycosidae), ground beetle (Coleoptera; Carabidae), earthworm (Annelida; Oligochaeta), rove beetle (Coleoptera; Staphylinidae)
Fate in soil:
DT50 was less than 3 days in aerobic conditions.
Fate in aquatic systems:
Acequinocyl is degraded by photolysis and hydrolysis. The photolytic half-life is 14 minutes. The rate of hydrolysis is dependent on pH, being faster at high pH.
