By reducing the amount of atrazine applied to the soil, runoff potential is reduced. Combine surface applications with postemergence atrazine. This two-step program often provides the best control of velvetleaf, cocklebur and other tough broadleaf weeds. Can maintain excellent weed control while reducing runoff potential. Alternative herbicides or non-chemical weed control methods.
New herbicides containing no atrazine are now available.
Using these herbicides reduces atrazine runoff by 100 percent . However, some of these herbicides do not control ALS-resistant weeds. The use of crop rotations, cultivation and other non-chemical weed control methods may reduce or eliminate the need for herbicides. Vegetative filter strips. Vegetative filter strips that reduce water flow rate from the field can reduce atrazine loss up to 25 percent .
