Abstract and summary

Downy brome (Bromus tectorum L.), and rattail fescue (Festuca myuros L.) were controlled by 2-methoxy-3,6-dichlorobenzoic acid (dicamba) and 2,4-bis(isoproplyamino)-6-methylmercapto-s-triazine (prometryne). Both herbicides gave 70–100% control when applied soon after the first postharvest irrigation. Dicamba was somewhat less effective when applied before this irrigation. Neither herbicide reduced seed yields when applied before or immediately after the first postharvest irrigation, but both herbicides caused some significant seed yield reductions when treatments were delayed until after considerable crop regrowth had occurred.
