EnvidorTM contains a novel acaricidal active ingredient, spirodiclofen, from the new chemical class of tetronic acids. This new contact acaricide is active against the citrus rust mite (CRM), Phyllocoptruta oleivora (Ashmead), and the pink citrus mite Aculops pelekassi (Keifer), the only two mite species recognized as economic pests on Florida citrus. In field tests conducted between 1996 and 2001 in Florida, Envidor, as a 240 g AI/liter suspension concentrate (SC) formulation, at rates ranging from 175.1 to 350.2 g AI/ha with and without horticultural spray oil provided significantly greater CRM control than commercial abamectin rates with oil at 52 days after application. Envidor 240 SC provided excellent control of all developmental stages of Eriophyidae and Tetranychidae mites, including eggs and adult females, through a new mode of action, inhibition of lipid biosynthesis. Moreover, Envidor has no cross-resistance to acaricides currently available in the market, which offers a powerful tool for pest management in citrus.
