Rimon 10EC Insecticide Now Registered Corn Earworm Control in Sweet Corn

By Jim Chaput, OMAFRA Minor Use Co-ordinator

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for RIMON 10EC Insecticide for control of corn earworm on sweet corn in Canada.  This new registration will provide sweet corn growers with a much needed pest management tool to control one of their most common insect problems. 

This minor use project jointly sponsored by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) and the U.S. IR-4 Program was submitted in 2007 in response to minor use priorities identified by producers and extension personnel in both Canada and the U.S.

The following is provided as a general outline only. Users should consult the complete label before using Rimon 10EC insecticide.

Rimon insecticide can be applied as a foliar spray at 820 mL per hectare for control of corn earworm.  Apply in 90 – 570 litres of water per ha and do not apply more than five applications per season.  Application should be made prior to peak oviposition at silking when adult activity is first observed or when egg hatch begins.  Do not apply within 9 days of harvest of sweet corn for hand harvesting and within 1 day of harvest of sweet corn for mechanical harvesting.  Re-application on a 7 day interval may be required when monitoring indicates a need.

Rimon insecticide should be used in an integrated pest management program and in rotation with other management strategies.  Follow all other precautions and directions for use on the Rimon insecticide label.

We also wish to acknowledge the personnel of Makhteshim Agan of North America Inc. and Chemtura AgroSolutions for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
