Herbicide Weed Control
Pre-plant incorporated herbicides are effective in controlling a broad spectrum of annual weeds early in the season. Incorporation of pre-plant herbicides dries and compacts the soil and buries crop residue, leaving it susceptible to wind erosion. Soil-applied herbicide should only be used in areas that receive adequate rainfall or where irrigation is available to activate the herbicide. Cultivation and hilling will disturb the herbicide treated soil allowing weeds to germinate, so apply pre-emergence herbicide after hilling.
