| Abstract/Contents: | Reports on a project undertaken to gain a better understanding of the biology and habit of the black cutworm in turf. "In experiments on golf greens mowed at two cutting heights, we found that black cutworm females laid nearly all of their eggs on the terminal ends of bentgrass leaf blades. Mowing alone removed 90 and 81% of the eggs laid on grass cut at 1/8 inch or 3/16 inch height, respectively. This means that most eggs laid on greens are likely to be mechanically removed by normal mowing practices. We suggest that damaging infestations may originate from cutworms migrating onto greens from surrounding fairways and roughs. Removing and disposing of clippings away from greens may be important for cultural control. All-night observations revealed that larval cutworms begin feeding about 10:30 p.m., but are most active between 2:30 and 4:30 a.m. These patterns suggest that to be most effective, treatments for cutworms should be applied in the evening to coincide with the larval feeding period." It was also found that black cutworms had no preference for aerated versus non-aerated turf, however, if the aerated plot was topdressed with sand, they prefered the non-aerated, non-topdressed turf. "This suggests that topdressing in conjunction with aerifying may help to deter colonization of greens by cutworms. More experiments are needed to confirm if this is true." |
