摘　　要：研究300、400、500、600、700倍稀释液10%大蒜素微乳剂对西瓜炭疽病的防治作用,室内药效和盆栽药效试验结果表明:不同倍数稀释液10%大蒜素微乳剂处理对西瓜炭疽病均有一定的防治效果,室内菌丝生长速率法测定其对西瓜炭疽病菌的抑制率分别为89.80%、76.00%、61.03%、51.63%、14.97%;室内离体叶片接菌鉴定其抑制率分别为81.81%、64.02%、59.10%、51.14%、1.82%;盆栽接种的防治效果分别为91.17%、75.72%、61.68%、43.53%、4.56%。由此可见,生产上使用10%大蒜素微乳剂300~500倍液能有效控制西瓜炭疽病害蔓延发展。Five different concentration of 10%allicin microemulsion were used to control watermelon anthracnose.The result of laboratory and pot experiments showed that all different concentration treatment of 10%allicin micro-emulsion had control effect to colletotrichum lagenarium in watermelon.The suppression ratio of mycelium growthrate methods were 89.80%,76.00%,61.03%,51.63%and 14.97%,respectively.The suppression ratio of isolatedleaf indoors by pathogen inoculation were 81.81%,64.02%,59.10%,51.14%and 1.82%,respectively.The controlefficiency to pathogen inoculated at the seedling stage through pot culture experiments were 91.17%,75.72%,61.68%,43.53%and 4.56%,respectively.In conclusion,using 10%allicin microemulsion 300~500 times solutionin production can effectively control the spread and development of watermelon anthracnose.
