Rimon® Insecticide Receives SLN in Washington for Codling Moth and Leafroller Control in Apples

05-04-2005: Rimon® 0.83EC Insecticide from Crompton Crop Protection has received a FIFRA Section 24(c) Supplemental Label for control of codling moth and other apple pests in Washington. Rimon has also been granted organophosphate (OP) replacement status by the EPA. In addition to codling moth, other pests targeted on the Washington SLN include obliquebanded leafroller, pandemis leafroller, redbanded leafroller, fruittree leafroller and variegated leafroller.

Rimon is a broad spectrum insecticide with a unique mode of action as a third generation chitin inhibitor. Unlike conventional insecticides that attack the nervous system of insects, Rimon works by disrupting chitin development in the exoskeleton. As the larvae/nymphs feed and attempt to molt, internal pressure on the weakened exoskeleton causes it to rupture, and the larvae/nymphs die before they reach the next growth stage. Developing larvae from eggs layed on Rimon treated tissues are unable to hatch.

This unique mode of action makes Rimon an excellent rotational product for resistance management and ideal for use in rotation with organophosphates and neonicotinoids. Rimon can be used in rotation with organophosphates for first generation (spring) applications and in rotation with neonicotinoids, Rimon has an excellent fit in second generation (summer) sprays.

Rimon is safe to beneficial insects because the beneficials feed on other insects, not on treated tissue. Safety to beneficials makes it an important component of Integrated Pest Management (IPM) programs.
