Abstract

Twenty-five winter wheat (Triticum aestivum L.) cultivars were sprayed with herbicides when in the tillering stage in April at North Platte, NE. In 1978, ‘Lindon’ and ‘Vona’ stands were reduced and grain yields of ‘Larned′, Lindon, ‘Roughrider′, 'Sage′, 'Scout 66′, 'Sentinel′, ‘Turkey′, and Vona cultivars were reduced by metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] plus pendimethalin [N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine] at 0.3 plus 2.8 kg ai/ha. There were no differences among cultivars in response to herbicides in 1979, 1981, and 1982. During 1980, wheat was more tolerant to a mixture of pendimethalin and 2,4-D [(2,4-dichlorophenoxy)acetic acid] than metribuzin plus pendimethalin. In 1981 and 1982, combinations of 2,4-D with pendimethalin or metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] did not reduce wheat yields. The mixture of pendimethalin plus 2,4-D performed satisfactorily in 4 yr of use.
