Abstract

Winter wheat infested with four populations of coast fiddleneck (Amsinckia intermedia Fisch. & May) was treated with 2,4–dichlorophenoxyacetic acid (2,4–D). One weed per square foot reduced grain yield. Weeds competed strongly as early as the rosette stage. Treating the weed infested wheat with 2,4–D increased yield. A vigorous, early-established crop of wheat competed effectively with the weeds.
