| Abstract/Contents: | "A demonstration on the use of Ethofumesate (prograss) was established at Veenker Memorial Golf Course in Ames in the fall of 1990. The objective was to evaluate the effectiveness of this material for the control of Poa annua on greens, tees, and fairways. On September 14, 1990, we applied the first application of Ethofumesate to the No. 14 fairway and green and to the No. 15 women's tee. On the fairway and tee, we used a rate of 0 (control), 0.50, and 0.75 pounds active ingredient per acre. Each test strip was 15 ft wide. The length of the fairway strips was approximately 50 yds. The strips on greens and tees were the length of those areas, respectively. Two additional applications were made to the same areas on October 22 and November 16. Loss of Poa annua was observed on the fairway and tee in the spring of 1991. The Poa annua on the green, however, was killed at all rates of Ethofumesate and remained healthy in the control strip. By late May, the percentage of bentgrass had increased greatly in the treated plots on the green, whereas the Poa annua was the predominate species in the control strip. No damage was observed on the bentgrass at any time during the fall or spring. The lack of Poa annua control on the fairway and tee is still a mystery. The areas were treated at the same time with the same sprayer, yet only the Poa annua on the greens was killed. The differences may be due to variations in biotype of the Poa on the areas, or there may have been some unobserved differences in environmental conditions among the areas. More work is planned for this fall to determine the reasons for the differences in control observed in the spring of 1991." |
