The California Department of Pesticide Regulation has granted a section 18 emergency use exemption for Intrepid 2F insecticide from DowDuPont to control armyworms in Butte, Colusa, Glenn, Merced, Sacramento, San Joaquin, Sutter, Yolo and Yuba counties.

The registration comes just in time as armyworm numbers are beginning to pick up in Northern California rice fields. University of California Cooperative Extension farm adviser Luis Espino has set up a series of traps throughout the rice-producing region.

The traps are designed to act as sentries, alerting the industry as armyworm numbers increase. Espino regularly publishes trap counts as well as what he is seeing in the field. You can sign up to receive his armyworm reports electronically.

If you decide to apply Intrepid, you must first make sure it is reflected on your restricted materials permit with the local county agricultural commissioner’s office.

This typically requires the permit holder to visit the ag commissioner’s office in person.

The various pesticide database companies will receive the section 18 label to index, providing pest control advisers access to write recommendations.

If considering alternatives to Intrepid 2F, please read and follow the pesticide label directions.

You can reference the table, Alternative Insecticides to Methoxyfenozide (Intrepid® 2F) for Use on California Rice, but do not use the information as a substitute for the registered label directions. ​
