Residual applications of CANOPY® require rainfall or sprinkler irrigation to activate the herbicide. Degree of control and duration of effect depend on: rate used, weed spectrum, growing conditions at and following time of treatment, soil pH, texture, organic matter, moisture and precipitation. Best residual control is obtained if DuPont Canopy is applied to moist soil and followed by rainfall or irrigation (1) before weeds germinate.
Several small rainfalls of less than 1/4 each are not as beneficial as one large rainfall of 1/2-1. On dry soil, more moisture is required for activation (1-2) before weed emergence.If moisture is insufficient to activate the herbicide, a rotary hoeing or shallow cultivation should be made after emergence of the crop while weeds are small enough to be controlled by mechanical means. Approximate use rate: varies, see label for specific application rate. Also see label for adjuvant or surfactant use rates. 4-Amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one..........
