Thiobencarb Fourth Week of Monitoring

Memorial Day weekend typically marks the fifth week of thiobencarb monitoring with peak use and numbers exceeding the 1.5 µg/L (parts per million) performance goal. For this atypical year, the holiday marked the fourth week of monitoring with numbers at all sites except the Sacramento River location. The monitoring results recovered to acceptable levels after a rough start where the performance goal was exceeded two and three weeks into the program.

We were hoping to provide monitoring results from the May 30 sampling event. However, those samples are still running at the laboratory and will be available next week for our next e-communication.

The season is far from over with temperature variations and winds in the forecast. Please keep up the great work in demonstrating how an industry can successfully manage a water quality program.

Lambda-cyhalothrin to be extensively monitored in Rice this year

We start monitoring Lambda-cyhalothrin (Warrior, Lambda-cy, Silencer, etc.) in the water column plus sediment sampling this year. The sampling takes place at the drain sites we use for thiobencarb monitoring. This will be our first experience with compliance to the Total Maximum Daily Load (TMDL) requirements. The TMDL is a forever monitoring program and we anticipate positive results leading to future modifications. We have never had an issue with our long history monitoring the pyrethroid insecticides. However, we have no ability to correlate the past results with the newer and much lower analytical methods.

Here are Key Links and Updates for Rice Pesticides

The following links include select pesticide updates as an effort to provide you with easy access to the information. Please remember the pesticide label is the ultimate level of enforcement and the county permit conditions can supersede the label with more restrictive requirements. You will find permit conditions and supplemental labels for thiobencarb. Permit conditions for some pesticides have been changed to active ingredient rather than trade or product name due to new product registrations. Products such as Butte Herbicide, RebelEx CA and RiceEdge 60DF are combination formulations and permit conditions could apply to one of the active ingredients. The EPA Reg. No. provides additional identification of the individual pesticide products on the Rice Pesticide Update Table.
