对农思它、氟乐灵、氨基氟乐灵、金都尔、秀百宫5种芽前除草剂在假俭草（Eremochloa ophiuroides）草坪建植期对杂草的封杀效果进行研究。结果表明，农思它会直接灼伤假俭草叶片，但其药害随时间延长能够逐渐恢复；秀百宫对假俭草有明显的药害，且药害随时间延长呈逐渐加重的趋势，对假俭草的生长也产生了严重的抑制；氨基氟乐灵、氟乐灵、金都尔对假俭草安全，施用后未产生明显的药害症状，处理后假俭草匍匐茎的生长不仅未受到抑制，而且其生长指标均高于对照。从这5种芽前除草剂对杂草的封杀效果来看，氨基氟乐灵表现最好，因此，可以推荐作为假俭草草坪建植期的芽前除草剂应用。%Five pre-mergence herbicides including Oxadiazon, Trifluralin, Barricade, S-metdachlor and Flazasulfuron were tested during the centipede turfgrass establishment period. The results showed that Oxadiazon will cause a direct and temporary leaf injury after herbicide application, but the injury was gradually recovered. Flazasulfuron caused significant and continuous injuries and growth inhibition to centipedegrass. Barricade, Turfluralin and S-metdachlor were all safe to centipedegrass, with no significant injuries occurred after their applications and all growth parameters measured were higher than the control. Barricade performed the best in the weed control among these three safety herbicides, and could be recommended for the weed control during the centipedegrass establishment.
