Abstract

In eight experiments conducted in north-eastern Victoria from 1965-1970, a range of herbicides were tested for selective post-emergence control of capeweed (Arctotheca calendula) in wheat and oats. Linuron, diquat, and bromoxynil were the best treatments tested and generally reduced capeweed density when applied in the early growth stages, causing little or no crop damage. Significant grain yield increases from spraying were obtained in each experiment with wheat, but in oats only one significant increase was obtained. Post-tillering treatments with 2,4-D and picloram plus 2,4-D did not increase grain yield.
