Penoxsulam as a turfgrass, vineyard and orchard floor herbicide

Abstract

Penoxsulam, 2-(2,2-difluoroethoxy)-N-(5,8-dimethoxy [1,2,4]-triazolo[1,5-c]pyrimidin-2-yl)-6-(trifluoromethyl)benzenesulfonamide, is useful in controlling broadleaf weeds and sedges in turfgrass and in vine and orchard floors.

1 . A method for controlling undesirable vegetation in turfgrass, vineyards and orchards which comprises contacting the vegetation or the locus thereof with, or applying to the soil to prevent the emergence or subsequent growth of vegetation, an herbicidally effective amount of penoxsulam.  
   
   
       2 . An herbicidal mixture comprising an herbicidally effective amount of (a) penoxsulam in admixture with an agriculturally acceptable adjuvant or carrier and (b) a fertilizer.  
   
   
       3 . A solid herbicidal mixture comprising an herbicidally effective amount of (a) penoxsulam in admixture with an agriculturally acceptable adjuvant or carrier and (b) a fertilizer, wherein the mixture is in the form of a granule having an average particle size of 0.5 to 2.5 millimeters.  
   
   
       4 . A synergistic herbicidal composition comprising (a) penoxsulam and (b) a second herbicide selected from the group of dicamba, 2,4-D, triclopyr, clopyralid, mecoprop-P and mixtures thereof.
