摘要: 立枯病是我国马蹄金草坪中常发病害,本研究测定了6种常用的杀菌剂对马蹄金立枯病病原菌的室内毒力及田间药效试验,以比较不同杀菌剂对马蹄金立枯病的控制效果,结果表明:正源(16%恶霉灵+40%甲基硫菌)、大扑因(50%异菌脲)和菌脱(45%多菌灵+5%菌核净)室内抑菌效果明显优于其他几种供试药剂。田间药效试验表明,正源、菌脱和大扑因1000倍液可对马蹄金草坪草立枯病起到较好的防治效果,相对防效分别为81.8%、76.7%和80.6%。

Abstract: Seedling blight is commonly occurred on dichondra repens turf in China. The control effects of 6 fungicides against seedling blight of dichondra repens were studied. The results showed that the antibacterial effects of ZhengYuan, Dapuyin and Juntuo are better than others in laboratory. The control efficacy of ZhengYuan, Dapuyin and Juntuo against seedling blight of dichondra repens were 81.8%, 76.7% and 80.6%, respectively, in field.
