Reducing Off-Site Movement of Atrazine and Pesticides

Reducing Off-Site Movement of Atrazine and Pesticides

The US Environmental Protection Agency is conducting an intermediate reassessment of atrazine label certification to ensure the safety of atrazine found in streams for aquatic life and human health.
As part of this effort Syngenta was required to set up 40 monitoring stations in potential runoff sites across the Midwest.

  • 31 of the 40 sites were below trigger levels of concern; 2 of these were in Nebraska.
  • 6 of the 40 sites exceeded the trigger level during one year; 3 of these were in Nebraska.
  • 3 sites exceeded the trigger level during both years; 1 of these was in Nebraska.

Syngenta proposed the next steps in the Watershed Management Program to include:

  • In 2010 continue monitoring atrazine runoff in Nebraska.
  • Continue to characterize atrazine use, conservation, and corn/milo acres.
  • Conduct stakeholder meetings to share monitoring information, raise awareness, and encourage stewardship practices to reduce runoff.
    EPA says scientific research data will be used in final decisions about further label adjustments.

Sensitive Crop Locater Website from Nebr. Dept. of Agriculture
This site is intended to identify locations within the state that grow sensitive crops such as grapes and organic. After the sites are identified, a pesticide applicator can locate those sites near them and take appropriate action to avoid injuring the crop with herbicide drift, etc.

Information presented within the crop production-Pesticides section of this Water Web site has been reviewed by University of Nebraska–Lincoln Cropping Systems Team members Richard Ferguson and Clyde Ogg.
