Bifenazate, a new acaricide for use on ornamentals in Europe and Africa

摘要

The acaricide bifenazate 240 SC has recently been introduced in European and African countries for use in the production of ornamentals. The target species for bifenazate is Tetranychus urticae (two-spotted spider mite), of which eggs and all motile stages are susceptible. Laboratory and field data on T. urticae, and side effects on other mite species are discussed. Resistance management is part of the introduction program, and results of cross-resistance studies are presented. Bifenazate has not shown any phytotoxic effect on a wide variety of cut flower and potted plant species, which were tested at concentrations up to twice the label rate. Bifenazate fits well in Integrated Pest Management programs, and effects on the main predators and parasitoids used in IPM are discussed.
