Safer control of broadleaf weeds in turf with granular formulations of ALS inhibiting herbicides
View Patent ↗The harmful effects of ALS inhibiting herbicides on turfgrass are reduced by applying the herbicides as solid granular compositions, particularly on solid granular fertilizer compositions.
1. A method for protecting turfgrass from the harmful effects of ALS inhibiting herbicides comprising the step of treating the turfgrass or the locus thereof with a dry solid granular herbicidal composition comprising an herbicidally effective amount of the ALS inhibiting herbicide in admixture with an agriculturally acceptable adjuvant or carrier.
2. A method of claim 1 in which the dry solid granular herbicidal composition comprises (a) an herbicidally effective amount of the ALS inhibiting herbicide in admixture with an agriculturally acceptable adjuvant or carrier and (b) a fertilizer.
3. A method of claim 1 or claim 2 in which the ALS inhibiting herbicide is an imidazolinone herbicide such as imazamethabenz, imazamox, imazapic, imazapyr, imazaquin and imazethapyr.
4. A method of claim 1 or claim 2 in which the ALS inhibiting herbicide is a pyrimidinylsulfonylurea herbicides such as amidosulfuron, azimsulfuron, bensulfuron, chlorimuron, cyclosulfamuron, ethoxysulfuron, flazasulfuron, flucetosulfuron, flupyrsulfuron, foramsulfuron, halosulfuron, imazosulfuron, mesosulfuron, nicosulfuron, orthosulfamuron, oxasulfuron, primisulfuron, pyrazosulfuron, rimsulfuron, sulfometuron, sulfosulfuron and trifloxysulfuron.
5. A method of claim 1 or claim 2 in which the ALS inhibiting herbicide is a triazinylsulfonylurea herbicide such as chlorsulfuron, cinosulfuron, ethametsulfuron, iodosulfuron, metsulfuron, prosulfuron, thifensulfuron, triasulfuron, tribenuron, triflusulfuron and tritosulfuron.
6. A method of claim 1 in which the ALS inhibiting herbicide is a triazolopyrimidine herbicide such as cloransulam, diclosulam, florasulam, flumetsulam, metosulam, penoxsulam and N-(5,7-dimethoxy-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)-2-methoxy-4-(trifluoromethyl)-3-pyridinesulfonamide.
7. A method of claim 1 or claim 2 in which the ALS inhibiting herbicide is a pyrimidinyloxybenzoic acid herbicide such as bispyribac and pyriminobac.
