| Abstract/Contents: | The effects of paraquat on young sward plots of a paraquat- resistant variety of Lolium perenne, PRP VII, infested with deliberately sown weed grasses were compared with the effects of the same treatments on a control variety, Aberystwyth S.101. In plots with PRP VII, paraquat applied at 0.3 kg a.i./ha almost eliminated the weed grasses, leaving an even sward of PRP VII, and leading to a much increased yield of the L. perenne component and higher digestibility of herbage cut in June; the total yield of herbage was reduced at this cut but increased in a second cut. In plots with S.101, the same treatment left a less even sward and had a smaller beneficial effect on botanical composition, a somewhat greater effect on digestibility, and a much more severe effect on total herbage yield. It is concluded that this new paraquat-resistant variety of L. perenne opens up new possibilities in grassland weed control which are precluded for normal varieties of L. perenne by their susceptibility to paraquat. |
