Rice Pesticide Registration remains a Major Focus

Many of you may be aware the state and federal offices have been closed for a year with staff working remotely. The government agencies are anticipating reopening around June. This has been less an issue for the CRC, since we have been working remote for several years and maintain a satellite office in downtown Sacramento. 

Regardless of the work situation, progress continues on the registration of pesticides. Here’s a brief update on pesticide registration actions the CRC has been involved this past year:

ALB2023 ROXY™ Rice Production System 

Ontrack for simultaneously submitting the registration packet to the U.S. EPA and Department of Pesticide Regulation (DPR) by end of March.

Chlorantraniliprole/Coragen (Prevathon or Ventacor)

Insecticide for armyworm control as a resistance management tool for Intrepid® 2F. Chlorantraniliprole is an IR-4 project (for residue data development) with the CRC as the applicant. Anticipate registration in 2023. 

Clethodim/ Select Max® Herbicide

Possible future spot treatment herbicide for weedy rice control. Clethodim is an IR-4 project with the CRC as the applicant. Anticipate a decision whether IR-4 will accept the project by September.

Copper sulfate/Various names

Preparing comments to support continuance of organic certification.

Florpyrauxifen-benzyl/ Lyoant with Rinskor® Technology

The Rinskor part of this product is registered and the Loyant pesticide portion is in the final stages of registration at the DPR. We anticipate registration for the current use season with no guarantee on a date. 

Methoxyfenozide/Intrepid® 2F

Was on track for registration as an armyworm product in 2021. The registration date has been revised to 2022. Intrepid® 2F will be a section 18 for the seventh year in 2021. This was the first IR-4 project for rice with the CRC as the applicant. 

Propanil/SuperWHAM!®

In communication with the registrant about additional studies on the formulation. 

Thiobencarb/Abolish® 8EC, Bolero® UltraMax, League® MVP, Willowood Thio UltraMax

Valent U.S.A. LLC and Generic Crop Sciences LLC are the two registrants. The CRC stewardship is available online. Here are links to the two different Thiobencarb courses:

CEU Course

Certificate Course

Additional work involves two herbicides and one fungicide. However, it is too early in the process to provide updates on these products.
