Thiobencarb Results improving

Thiobencarb Results improving

Thiobencarb monitoring was off to a rough start with nine exceedances of the 1.5 µg/L (parts per billion) performance goal in the agricultural drains. The performance goal, established in 1991, is set in the Central Valley Water Board Basin Plan. Our concern was the exceedances began the second week of monitoring rather than the typical mid-season timing coordinating with Memorial Day. 

Fortunately, we have had no detections in the river, which is the point of compliance for the Central Valley Water Board. The water quality objective in the river is 1.0 µg/L at the city drinking water intakes. The water quality objective is set at a level to mitigate nuisance from taste and odor from thiobencarb elevated levels. 

The monitoring season will extend until July 16. We are positive the monitoring results through June 18 will continue through the end of the season.

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.
