| Abstract/Contents: | Paraquat was applied at 1.1 and 2.2 kilograms per hectare and glyphosate at 2.2,4.5, and 9.0 kilograms per hectare to a mature Kentucky bluegrass (Poa pratensis) turf at two sites to evaluate the impact of thatch on residual activity of the herbicides as it affects the establishment of perennial ryegrass (Lolium perenne) from seed. One site had 2 centimeters thick thatch, and the other with no thatch. The plots were cultivated four days later in the following manner: disk seeded; core cultivated, vertically mowed, and broad cast seeded. Differences in coverage were observed between herbicide treatments and reestablishment method. Herbicide treatment had no adverse affect on stand coverage on the reestablishments of thatch-free sites. Under thatchy conditions the residual activity of paraquat was observed, as evidenced by a reduction in stand coverage. The utilization of other establishment methods reduced paraquat injury by allowing for better contact between the seed and the soil, since cultivation methods removed most of the thatch layer (vertical mowing) or introduced soil at the site of seed germination (coring). Differences in the amount of paraquat injury between spring and late summer studies suggest that environmental factors may also affect the residual activity of paraquat in thatch. |
