春季草坪杂草化学防除要点一、阔叶杂草的防除使他隆、二甲四氯、麦草畏、2,4-D、快灭灵、巨星、坪安1号等都可以有效防除早熟禾、高羊茅、黑麦草、结缕草、狗牙根等禾本科草坪草中的常见阔叶杂草。使他隆在杂草3叶期左右使用，但它对泽、水花生、空心莲子菜、莎草、播娘效果不好。二甲四氯在杂草5叶期以内使用，对泽漆、水花生、空心莲子菜几乎无效，对莎草有抑制作用。2,4-D的效果相似，当气温在15℃以上时易发生药害。巨星在杂草3叶期左右使用，对泽漆、水花生、空心莲子菜、莎草无效，对播娘蒿、猪殃殃效果不好，对多年生杂草无效。坪安1号在杂草9叶期以前使用，对绝大多数杂草均有很好的防效，对恶性杂草莎草、空心莲子菜有除根的效果。防除阔叶草坪草中的阔叶杂草，如对于豆科草坪中的阔叶杂草，使用苯达松进行防治，草坪会有灼伤，3至4天可恢复。二、禾本科杂草的防除对于阔叶草坪草(马蹄金、酢酱草、白三叶)中的禾本科杂草，使用精禾草克、精稳杀得、盖草能、拿捕尽等除草剂可干净地杀灭多种禾本科杂草，如稗草、牛筋草、狗尾草、狗牙根、马唐等。麦冬中的禾本科杂草可以参考阔叶草坪用药，禁止使用2甲4氯和2,4-D类除草剂。禾本科草坪草中的禾本科杂草，使用坪安5号可以进行有效防除(杂草9叶期以内)，兼除部分阔叶杂草(5叶期以内)。三、莎草科杂草的防除禾本科草坪草中的莎草科杂草，可以使用坪安1号进行防除，使用两次可彻底除根。对于阔叶草坪草中的莎草科杂草，可以使用仅对莎草有特效的莎扑隆，对多种草坪安全，但必须进行土壤混合处理，且用量较大，成本较高，难于推广。dimethenamide杀草谱广，除对香附子有效外，还能防除多种禾草和阔叶草，对豆科草坪草安全。此外，三唑磺酰胺类除草剂F－628是一种播前混土或播后苗前土表处理的除草剂，适用于豆科草坪草，杀草谱很广，对香附子防效好，持效期较长，能与多种除草剂混用。四、多种杂草同时发生的化学防治可参考以上方法。（来源：《中国花卉报》2004.04.06）
