Abstract
This invention relates to a synergistic composition made of a herbicidally effective amount of a propanil-based product, such as SUPER WHAM® and the at least one ACCase inhibitor herbicide such as CLINCHER® in an amount sufficient to facilitate the herbicidal activity of the propanil-based herbicide. It has been found that this synergistic composition, when applied to a field of rice, allows a reduction in the amount of herbicide needed, greater flexibility in timing of the application and broad spectrum of weed control.
Claims5
A method to use at least 20 percent less propanil based herbicide to control weeds, while cultivating rice in a field, comprising the steps of:
- applying to said field an amount of a propanil based herbicide with a herbicidally ineffective amount of cyhalofop, to form a herbicidally effective composition, wherein the weight ratio of the herbicidal effective compound ranges from about 1 pound of propanil to about 0.009 to 0.04 lbs. of cyhalofop wherein the amount of propanil applied is selected from the group consisting of:
- the weeds are grass at 2 to 3 leaf stage and the amount of propanil is 2 pounds per acre;
- wherein the weeds are grass at 3 to 4 leaf stage and the amount of propanil is 3 pounds per acre;
- wherein the weeds are grass at 4 to 5 leaf stage and the amount of propanil is 4 pounds per acre and wherein the weeds are grass at 5 leaf stage and wherein the weeds are grass at 6 leaf stage and the amount of propanil is 6 pounds per acre.
