Abstract

The tolerances of wheat and wild buckwheat (Polygonum convolvulus) to various rates of 2-methoxy-3,6-dichlorobenzoic acid (dicamba) were determined under field conditions and supplemented by studies with wheat in the growth chamber. Wheat height and yield were inversely proportional to rate, but response to various rates was dependent on stage of growth at application. Greatest reductions in wheat height and yield resulted from treatment at the late tiller and boot stages, respectively. The weight per 100 wheat seeds was increased from treatment at the boot and flower stages but was decreased at the early tiller stage.

The ratio of peduncle length: length of the flag leaf-sheath was decreased most from 24 oz/A applied preemergence and 12 oz/A applied at the late tiller stage.

Growth rate of wheat was decreased for a 2-week period after treatment. Excellent kill of wild buckwheat was observed from all rates applied through the 12- to 15-leaf stage of growth.
