Synergistic herbicidal composition containing penoxsulam and oryzalin

Abstract

An herbicidal synergistic composition containing (a) penoxsulam and (b) oryzalin provides improved post-emergence herbicidal weed control in tree and vine crops, turf, sugar cane, range and pasture, parks and alleyways, and IVM.

1 . A synergistic herbicidal mixture comprising an herbicidally effective amount of (a) penoxsulam and (b) oryzalin. 
     
     
         2 . The synergistic herbicidal mixture of  claim 1  in which the weight ratio of oryzalin to penoxsulam on an active ingredient (ai) basis is from about 40:1 to about 960:1. 
     
     
         3 . A synergistic herbicidal composition comprising an herbicidally effective amount of the synergistic herbicidal mixture of  claim 1  and an agriculturally acceptable adjuvant or carrier. 
     
     
         4 . A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with an herbicidally effective amount the synergistic herbicidal mixture of  claim 1 . 
     
     
         5 . A method of controlling undesirable vegetation in fruit trees, including pome, stone, tree nut, citrus and olives, grapevines, turf, sugar cane, parks and alleyways, range and pasture and in industrial vegetation management which comprises contacting the vegetation or the locus thereof with an herbicidally effective amount the synergistic herbicidal mixture of  claim 1 .
