- Evaluate the potential of controlling hairy nightshade with tankmixes of ethofumesate and s-metolachlor and determined table beet tolerance to s-metolachlor in a commercial production system.
Hairy nightshade control with Dual Magnum improved nearly linearly as the rate of Dual Magnum increased. Hairy nightshade control improved significantly when Dual Magnum was tankmixed with Ethotron, and the increase in efficacy was most apparent with Ethotron tankmixed at 15 and 30 oz/A. In a commercial field, Dual Magnum significantly improved weed control, but may have reduced yield where irrigation was excessive.
