Rainfall

Rainfall is required following application to activate the herbicide and for adequate weed control.
Grazing
:
Do not graze treated crops or cut for hay.

Environmental Precautions
Do not fill mix or clean sprayer within 15 m of any water source, unless the well is properly capped or activities take
place on impervious pads or properly diked mixing/loading areas. Leave a 1 m buffer between the last spray path
and water or wetland habitats and 10 metres to sensitive plants and upland habitats when applying by ground. Buffer
zones can be reduced by 70% when using shrouds and by 30% when using cones mounted less than 12 inches from
the crop canopy.
