Raptor herbicide, a soluble liquid, is a postemergence herbicide to control and suppress many broadleaf and grass weeds and sedges, as listed in this label.
The mode of weed-killing activity involves uptake of Raptor by foliage and/or weed roots and rapid translocation to the growing points. After Raptor application, susceptible weeds may show yellowing, and weed growth will stop. Susceptible weeds stop growing and either die or are not competitive with the crop.
Adequate soil moisture is important for optimum Raptor activity. When adequate soil moisture is present, Raptor will provide residual activity on susceptible germinating weeds. Activity on established weeds will depend on the weed species and the location of its root system in the soil. A timely cultivation after Raptor application may improve weed  control.
