Abstract/Contents:The use of herbicides Endothal (Endothall) and Nortron (Ethofumesate) have been popular chemical control methods for annual bluegrass (Poa annua L.) for many years. Recently, interest has been generated about the use of the fungicide Rubigan (Fenarimol) for controlling annual bluegrass. In a study conducted at WSU, Rubigan, Endothal and Nortron were tested for control of annual bluegrass seedlings, and their effects on bentgrass turf. The experiment was divided into two areas of study: a greenhouse study and a field study. The objectives of the greenhouse study were to compare annual bluegrass control with Rubigan, Endothal, and Norton, with different application rates at various growth stages. Rubigan, Endothal, and Nortron were all successful in controlling annual bluegrass. It should be remembered that the rates of Rubigan used were the recommended rates for the control of annual bluegrass, and are much higher than the recommended rates for disease control. Annual bluegrass was better controlled at the early growth stages than at the older stages. While all three were successful at controlling annual bluegrass, they also had an effect on bentgrass turf. Endothal caused the least amount of turf injury over the 30 day test period. Nitrogen and iron were successful in mitigating the injury caused by the herbicides, with the effects dependent upon the timing of the mitigator application and the herbicide used.
