Abstract
Methods for controlling the growth of trifluralin-resistant annual ryegrass in cereals using dithiopyr are described. The methods include contacting the locus of the cereal, at planting or before weed emergence, with an herbicidally effective amount of dithiopyr. The dithiopyr can be applied to the soil and either incorporated into the soil at the time of planting the cereal or applied post-planting to the soil surface before the weeds have emerged.
Claims18
A method of controlling the growth of trifluralin-resistant annual ryegrass in cereals, comprising contacting a locus of a cereal in an area that contains or will contain trifluralin-resistant annual ryegrass, at planting or before weed emergence, with a composition comprising a herbicidally effective amount of dithiopyr.
A method of controlling the growth of trifluralin-resistant annual ryegrass in cereals, comprising applying to an area containing a cereal and containing or will contain the trifluralin-resistant rye grass a composition comprising dithiopyr at a rate of 250 or fewer grams active ingredient per hectare.
A method of controlling the growth of trifluralin-resistant annual ryegrass in wheat, barley, or triticale, comprising applying to an area containing the wheat, barley, or triticale and containing or will contain the trifluralin resistant annual ryegrass, at planting or before weed emergence, a composition comprising an herbicidally effective amount of dithiopyr and one or more additional cereal herbicides, wherein the dithiopyr is applied at a rate of 250 or fewer grams active ingredient per hectare.
