acaricide

noun

1. Any substance which kills acarids (mites and ticks).

   ““Twelve pesticides commonly applied to citrus groves are slated for study in the project’s plots,” reports Tom S. Bellows, UC Riverside assistant entomologist. They include four acaricides (Morestan, Kelthane, Pictran, Vendex), four thripsicides (Cygon, Carzol, Orthene, Sabadilla), and four scalicides (Parathion, Supracide, Lorsban, Sevin).”

   “Diagnostic doses of six acaricides (fenothiocarb, endosulfan, chlorfenapyr, tebufenpyrad, cyenopyrafen and cyflumetofen) resulted in a 68.0~71.8% mortality rate (on average) in the test mite populations, whereas the remaining six acaricides (monocrotophos, omethoate, bifenthrin, abamectin, etoxazole and bifenazate) caused slightly reduced mortality rates (on average 36.5~59.3%).”
