Thiobencarb Monitoring Season Set to Start

Monitoring for 2020

Thiobencarb monitoring starts at all five sampling sites tomorrow, April 28. We base the monitoring on planting and timing of thiobencarb applications with several counties receiving notices of intent to apply Abolish. 

Monitoring typically takes place on Tuesdays and Thursdays except this year with the addition of Wednesday during certain weeks. We are on an assessment monitoring schedule with the Rice WDR, which expands sample collection beyond a Tuesday/Thursday program. The total thiobencarb monitoring will remain a ten-week schedule and include the same number of samples as previous years.

Changes to the REI and field posting

The thiobencarb restricted entry interval (REI) was decreased from 7-days to 12-hours. The change is reflected in a supplemental label, which must be present and available (in-hand) at time of application. Without the supplemental label, you are held to the 7-day REI and field posting requirements. You can receive the supplemental label from your Valent representative, thiobencarb suppliers or a link to the CRC pesticide update provided last week. 

For more information, contact the CRC’s Industry Affairs Manager Roberta Firoved at rfiroved@calrice.org or (916) 206-5039.
