摘　　要：以北方冷季型高羊茅草为试材,进行了28.2 g/L嘧菌酯·10.9 g/L精甲霜灵悬浮剂495 g/hm^2,28.2 g/L嘧菌酯·10.9 g/L精甲霜灵悬浮剂1 005 g/hm^2和50%嘧菌酯水分散粒剂1 200 g/hm^2对观赏草坪腐霉病的田间预防治疗比较试验。结果表明,采用发病前和发病初期喷雾的预防性防治方法,28.2 g/L嘧菌酯·10.9 g/L精甲霜灵悬浮剂495 g/hm^2的防治效果最佳,其防效达到92%;其次为28.2 g/L嘧菌酯·10.9 g/L精甲霜灵悬浮剂1 005 g/hm^2,防效为90.19%。研究结果对于草坪腐霉病的防治具有指导作用。The effect of 3 treatments, including the low dose （495 g/hm2） and high dose （ 1 005 g/hm2） of 28.2 g/L Azoxystrobin ·10.9 g/L metalaxyl-M suspending agent and 50% Azoxystrobin water dispersible granule, on turfgrass Pythium disease were compared on northern cold-season tall fescue in the field. The results showed that the control efficacy of low dose of 28.2 g/L Azoxystrobin ~ 10.9 g/L metalaxyl-M suspending agent was 92%, followed by the high dose with a control efficacy of 90.19%. And the control efficacy of 28.2 g/L Azoxystrobin ＂10.9 g/L metalaxyl-M suspending agent was significantly higher than that of 50% Azoxystrobin water dispersible granule （P 〈 0.05 ）. This study will play a guiding role for the prevention and control of turfgrass Pythium disease.
