Abstract
Field bindweed (Convolvulus arvensisL.) was controlled most effectively when glyphosate [N-(phosphonomethyl)glycine] was applied as a foliar spray to blooming field bindweed. This control resulted in significant yield increases of winter wheat (Triticum aestivumL.). Earlier growth stage treatments were less effective. Dicamba (3,6-dichloro-o-anisic acid), used similarly, controlled field bindweed but caused injury to the following wheat crop. Preharvest treatments of glyphosate in wheat aided harvesting operations and controlled the perennial field bindweed through the summer. Several dinitroaniline herbicides applied as a subsurface layer (SSL), controlled field bindweed for more than 8 months after treatment. However, these treatments caused visible injury and affected the yield of the first crop of wheat but had little effect on a second crop. Dicamba applied SSL at lower rates resulted in excellent field bindweed control.
