【摘要】 用２５％ＳＬ—１６０颗粒剂对马尼拉草坪进行了茎叶处理和土壤处理。结果表明，１５０～３００ｇ／ｈｍ２茎叶处理可有效地防除香附子、天胡荽、牛繁缕、大巢菜等草坪杂草，药后６０ｄ对香附子的校正防效为８０．５９％～１００％，对天胡荽的校正防效为７１．５８％～１００％，施药时加入８８５助剂２２５ｍｌ／ｈｍ２可适当提高药后早期的防效，但对最终防效影响不明显；１５０～３００ｇ／ｈｍ２作土壤处理，对杂草的出苗影响不大，但对出苗后杂草的生长却有很强的作用，药后６５ｄ对马唐、牛筋草、狗尾草、香附子的鲜重防效分别为１００％、７８．４０％～９９．５％、９５．６０％～９９．７０％、８７．２０％～９９．６０％。更多还原

【Abstract】 SL-160 (flazasulfuron) is a sulfonylurea herbicide developed by ISK (Japan) for weed control in warm season turfgrass. Foliar treatment were carried out at dosage ranging from 150～300g/hm 2 (25%G) against seedling of weeds, such as nutgrass (Cyperus rotundus), Lawn perrywort (Hydrocotyle sibthorpiodes), giant chickweed (Stellaria aquatica), Common vetch (Vicia sativa) in manilagrass (Zoysia matrella). The effects were from 80.59%～100%, from 71.58%～100% respectively for nutgrass, lawn prnnywort after 60 days application. At the same dosages, fresh weight of crab grass (Digitaria sanguinalis), green foxtail (Staria viridis), bullgrass (Eleusine indica), nutgass were reduced by 100%, 78.40%～99.50%, 95.60%～99.70%, 87.20% ～99.60%, respectively in soil surface treatment after 65 days application. SL-160 can not kill Seedweed (Veronica persica) and False grape (Cayratia japonica).更多还原
