| Abstract/Contents: | Dithiopyr (Dimension) is a new herbicide labeled for use on Kentucky bluegrass and other turf species in 1991. It functions both as a preemergence and early postemergence control of crabgrass. The objectives of this study were to observe rooting responses and foliar phytotoxicity to dithiopyr on creeping bentgrass mowed at 3/16-inch and maintained under putting green conditions. This is the 3rd year of this study at Iowa State University. Root samples were collected on June 9 and August 7 to a depth of 20 cm (Table 17). The diameter of the cores was 2.54 cm and six cores were collected per plot. The samples were divided into four subsamples cut in 5 cm increments: 0-5, 5-10, 10-15, and 15-20 cm. All soil was washed from the root samples, the samples were dried weighed, and ashed at 500°C. Root weights were reported as the difference between ashed and dry weights. Bensulide was used as a standard in this trial as it labeled for use on bentgrass greens. Root weights of dithiopyr-treated bentgrass were generally similar to that of Bensulide-treated plots. This information combined with the lack of phytotoxicity has shown that after three years of repeated treatments, dithiopyr was generally safe for use on 'Penncross' creeping bentgrass maintained at green height under the conditions established in this study. |
