摘　　要：为了有效提升海南省高尔夫球场草坪的养护管理水平,对海南省具有气候代表性的高尔夫球场草坪进行真菌病害调查,并测定6种杀菌剂对不同病原菌的室内毒力及防控效果。结果表明,目前海南省高尔夫球场种植草坪草主要为海滨雀稗和杂交狗牙根,主要的真菌病害有11种,分别为币斑病、镰刀菌枯萎病、全蚀病、仙环病、条锈病、炭疽病、褐斑病、黑痣病、粉斑病、红丝病、黑孢霉枯萎病。甲基托布津和五氯硝基苯对镰刀菌枯萎病病原菌的抑制作用最强,EC_(50)分别为0.02μg/mL和0.08μg/mL;代森锰锌对仙环病病原菌的抑制作用最强,EC_(50)为0.10μg/mL;福美双对炭疽病病原菌的抑制作用最强,EC_(50)为0.37μg/mL;多菌灵对红丝病病原菌的抑制作用最强,EC_(50)为0.93μg/mL;粉锈宁对粉斑病病原菌的抑制作用最强,EC_(50)为0.06μg/mL。甲基托布津对草坪病害的防治效果最好,达66.0%;五氯硝基苯和代森锰锌也有一定的防治效果,分别为57.6%和52.2%。在球场草坪养护过程中,可将这几种药物交替使用或混合使用。In order to effectively improve the maintenance and management level of golf course lawn in Hainan province,this study investigated the fungal disease of the climate representative golf course lawn in Hainan province,and determined the indoor toxicity and control effect of six fungicides. At present,Paspalum vaginatium Sw and Cynodon dactylon( Linn.) were mainly planted in Hainan golf course lawn,and there were 11 main fungal diseases on golf course lawn,namely coil spot,fusarium wilt,take-all,fairy ring disease,stripe rust,anthrax,brown spot,nevus disease,pink patch,red thread,Nigrospora wilt. Methyl thiophanate and pentachlorobenzene had the highest inhibitory effect on the pathogen of fusarium wilt,and EC_(50) were 0. 02 μg/mL and 0. 08 μg/mL,respectively. The inhibitory effect of mancozeb on the pathogen of fairy ring disease was the highest,and EC_(50) was 0. 10 μg/mL. The inhibitory effect of thiram on the pathogen of anthracnose was the highest,and EC_(50) was 0. 37 μg/mL. The inhibitory effect of carbendazim on the pathogen of red thread disease was the highest,and EC_(50) was 0. 93 μg/mL. The inhibitory effect of triadimefon on the pathogen of pink spot disease was the highest,and EC_(50) was 0. 06 μg/mL. The control effect of methyl thiophanate on lawn disease was the best,up to 66. 0%,and the control effects of pentachlorobenzene and mancozeb were 57. 6% and 52. 2% respectively. During the maintenance of lawn,these drugs can be used alternately or mixedly.
