Preemergence Herbicide Combinations for Weed Control in Cantaloupes

Sandea, Valor, and Outlook offered promising results in different combinations applied preemergence (PREE). The combination of Prefar plus Sandea gave 95% control of pigweed and continued to control lambsquarters at 90% late in the season. Prefar combined with Valor gave acceptable pigweed control and lambsquarters were controlled at acceptable levels at 88 and 86%, respectively. Outlook combined with Valor was safe and gave good early pigweed control and later control of lambsquarters. Strategy alone at either 1.0 or 2.0 pt/A did not provide acceptable levels of weed control and no significant crop injury was observed
