General Product Information

Category

Insecticides > Pyrethroid insecticides
Acaricides / Miticides > Pyrethroid acaricides

Activity

Acaricide/Miticide.
Acrinathrin is active by contact and ingestion and rapidly kills larvae and adults of phytophagous mites and some hemipteran insects. The compound has good knock-down activity and residual activity lasting several weeks. This prevents re-infestation and controls the progeny of surviving adults. The optimum time for spraying is at no more than five larvae/adults per leaf. Acrinathrin does not cause russeting in apples at the recommended rates.

Acrinathrin is widely used for the control of Varroa spp, the major mite pest of bees. The trade name Gabon is used for wood veneer strips impregnated with the miticide.

One application of acrinathrin is recommended per season to prevent the build-up of resistance. The company recommends the use of acrinathrin in resistance management and IPM programmes.

In Italy, Bayer has developed Rufast E-Flo, an EC formulation based on vegetable oil and has shown the product to be safe to bees when applied to indoor tomatoes for the control of Frankliniella occidentalis. In this type of cultivation, which represents over 70% of the market in Italy, the bees are used for pollination of plants, replacing the traditional method based on hormone applications.

Fate in soil:
Acrinathrin is strongly adsorbed by soil particles and is classified as immobile. It is degraded in soil and has a half-life of 3-27 days.

Fate in aquatic systems:
Acrinathrin is rapidly degraded by hydrolysis in aqueous systems.
