摘    要:在重庆市万州区通过田间调查和室内镜检,发现草坪草上发生的主要病害是叶褐斑病和锈病,其次是德氏霉叶枯病(网斑病)和炭疽病,黑粉病、炭疽病、白粉病、镰刀枯萎病、腐霉病也有不同程度的发生。通过对褐斑病、锈病的室内药效试验和田间防治试验,结果表明斑粉脱、力克菌、三唑酮、百·乙、星灿、苗菌敌、根腐灵、多菌灵、绿亨一号均具有明显抑菌及防治效果;抑防锈病以斑粉脱效果最好,抑防褐斑病以苗菌敌和绿亨一号效果最好。

Abstract:Field investigation and indoor microscope examination indicated that leaf brown spot and rust were the major diseases in sod grass in Wanzhou,Chongqing,meanwhile,leaf blight,anthracnose,smut,powdery mildew,fusarium wilt and fowl-brood happened in different degrees.Chemicals such as myclobutanil,diniconazoie,tridimefon,diethofencarb chlorthalonil,carbendazim thiram,carbendazim quintozene,carbenazim and hymexazol had a significant bacteriostatic and control effect on the two major diseases,leaf brown spot and rust. Myclobutanil was the most effective fungicide to control rust,while carbendazim thiram and hymexazol did the best on the control of leaf brown spot.
Keywords:Cold-type sod grass  Diseases  Chemical control
