Introduction
Postemergence - Leaf stage of the weeds is critical
for good weed control. Smaller weeds are generally easier to kill but
there needs to be enough leaf surface to intercept the herbicide. Apply
according to recommended leaf stages. Crop stage is important to optimize
crop safety. Adjuvants will frequently improve the weed control when used
as directed. Weather or other conditions may influence the optimum rate
of adjuvant, see the product label for more details. Always use appropriate
drift management technology.
