摘要
以供试茼蒿炭疽病病菌为试材,研究了12种农药对茼蒿炭疽病病原菌的抑菌效果。结果表明:戊唑醇的抑菌效力及药效持久性与其它农药处理差异显著;其次是己唑醇、百菌清和代森锰锌;再次是异菌脲、恶霉灵和霜霉威盐酸盐,但恶霉灵和霜霉威盐酸盐药效持久性差;其余农药处理的抑菌距离与对照差异不显著。菌落生长速率测定结果表明,戊唑醇、己唑醇、百菌清和代森锰锌这4种处理,没有菌落生长,具有良好地抑菌杀菌效果;异菌脲、恶霉灵处理的菌落边缘菌丝矮小、稀疏、生长不良,说明有一定的抑菌杀菌效果,其它农药抑菌杀菌效果不明显。
The antibacterial effects of 12 reagents on Chrysanthemum coronarium anthracnose were studied in this paper.The results showed that tebuconzole was better than others treatment significantly in the antibacterial effect and persistence.Secondly were hexaconazole,chlorothalonil and mancozeb,and the next were iprodione,hymexazol and propamocarb hydrochloride.The persistence of hymexazol and propamocarb hydrochloride was the worst.Inhibition zone of other reagents had not significant difference with control.The rusults of colony growth rate showed that no colony was found with treatments by tebuconzole,hexaconazole,chlorothalonil and mancozeb,which antibacterial and germicidal efficacy was good.On edge of colony,mycelium was dwarf,sparse and grew bad when it was treated by iprodione and hymexazol,which suggested the two reagents had some antibacterial effects.Germicidal efficacy of other regents was not obvious.
