Abstract

Postemergence spring applications of picloram and picloram plus 2,4-D frequently reduced mature height and peduncle length of hard red winter wheat in field experiments. Yield reductions were more severe from picloram applied alone to the first joint growth stage than late tillering stage wheat. In two of six experiments picloram plus 2,4-D reduced yield more than picloram alone. Yields of four wheat cultivars were reduced by picloram and picloram plus 2,4-D at one of two locations. At the second location only the yield of ‘Chisholm’ and ‘Rohm and Haas Seed 7837’ were reduced by those herbicides.
