Intrepid® 2F Insecticide is approved to combat Armyworm

The Intrepid® 2F Insecticide (EPA Reg. No. 62719-442) section 18 has been approved for use in Butte, Colusa, Glenn, Merced, Sacramento, San Joaquin, Sutter, Yolo, Yuba Counties.

You need to make certain Intrepid® 2F Insecticide is on your rice pesticide (restricted materials) permit at the county agricultural commissioner’s office. The various pesticide database companies will receive the section 18 label to index, providing pest control advisers (PCAs) access to write recommendations.

If considering alternatives to Intrepid® 2F Insecticide, please read and follow the pesticide label directions. You can reference the table, Alternative Insecticides to Methoxyfenozide Registered for Use on California Rice, but do not use the information as a substitute for the registered label directions.

All section 18 labels are product and not active ingredient (pesticide) specific. The Intrepid® 2F Insecticide (EPA Reg. No. 62719-442) is the only methoxyfenozide product that legally can be used on rice. Use of any generic methoxyfenozide products is illegal and could harm future authorizations for usage of the insecticide for armyworm control.
