Downwind Requirements


Adjacent Sensitive Crops and Certain Plants

DO NOT SPRAY when wind is blowing toward adjacent sensitive crops and/or certain plants as defined on the label.


Downwind Buffer

After determining no adjacent sensitive crops and/or certain plants are downwind, maintain a 240-foot downwind buffer in non-ESA counties.


Endangered Species

Consult Endangered Species Protection Bulletins for ESA counties and restrictions.

Optional Use of Drift Reduction Technology


Drift Reduction Technology

Use of qualified hooded/shielded broadcast sprayers results in a reduced downwind buffer distance of 110 feet in Non-ESA counties.

For incidence of non-performance or off-target movement or for questions regarding buffer requirements or sensitive crop registries, call 1-844-RRXTEND.

For best results, spray weeds that are less than 4 inches tall.
