New Envidor 2 SC miticide from Bayer CropScience is now labeled for use on citrus, pome fruits, stone fruits, grapes and tree nuts following registration from the California Department of Pesticide Regulation (DPR).

“Envidor is a selective, foliar miticide that contains the active ingredient spirodiclofen, a member of the new chemical class called tetronic acids,” says Jon Mixson, Envidor product manager. “It effectively controls brown mites, European red mites, Pacific mites and two-spotted spider mites.

Plus, Envidor has a unique mode of action classified as a Lipid Biosynthesis Inhibitor (LBI), which is different from other types of miticides available in the marketplace.”

Because there is no cross-resistance to other miticides, this novel mode of action makes Envidor a critical tool for effectively managing mite resistance.

Mixson explains that Envidor is active against all life stages of mites, including eggs and female adults. Immature mites die soon after treatment with Envidor because they can't grow into the next development stage, he says. And treated adult females deposit fewer eggs. “Mites treated with Envidor may still be visible for several days following treatment, but aren't damaging plants and will die soon,” Mixson points out.

Flexible application timing is another benefit of Envidor. For optimal results, Envidor should be applied as either a preventive treatment or at early threshold when mite populations begin to build.

Envidor does not harm many beneficial insects including predacious bugs, parasitic wasps, lacewings and ladybird beetles. However, eliminating mites as prey will affect the beneficial populations by reducing their food source. And, to avoid a possible impact on bees, Envidor should not be applied to target crops during flowering.

Compatible with many crop protection products, Envidor is rainfast after it has dried and is not degraded by high temperatures or light.
