Thiobencarb (Bolero/Abolish/League) is under strong scrutiny even as we face another drought. The product has been in non-compliance with exceedances in the drains for the last two years.
Monitoring began on our traditional date of the last Tuesday in April. We may add additional dates to the monitoring calendar in June and July to accommodate the sporadic start to planting.
Our main concern is the Memorial Day weekend, since the results spike at that time. We will monitor three days the week before the holiday weekend and two days the following week. The reason for three days in lieu of two is to coordinate with the assessment monitoring for the Rice Waste Discharge Requirements.
