The electron microscope scanning results showed that dense mycelia and conidial colonies were observed on the leaves of non K2SiO3-applied plants, while loosened mycelium or no mycelium on the leaf surface of K2SiO3-applied plants.

经电镜扫描分析显示，诱导接种后，未加硅酸盐的叶片布满浓密的菌丝体及分生孢子团，经硅酸盐处理的叶片上仅有松散的菌丝或者没有菌丝分布。

Lagenarium was higher 60%(for example, Glycyrrhiza yralensis, Lycium barberum and Desmodium styracifolium) as the concentration 0.01g/ml. Especially, the G. yralensis showed the strongest inhibitory effect on it with inhibitory rate of 99.6%. The inhibitory rate of 12 PE against mycelium growth and 15 PE against appressorium formation of C.

供试提取物在质量浓度为0.01 g/ml条件下，甘草、枸杞、金钱草等11种植物的80%乙醇提取物对黄瓜炭疽病菌分生孢子萌发的抑制率大于60%，其中甘草的抑制作用最强，达99.6%；12种提取物对黄瓜炭疽病菌菌丝生长的抑制率大于50%；15种提取物对黄瓜炭疽病菌附着胞形成抑制率达50%。

There were no significant differences （P〉 0.05） between the four mutants and Chy-1 in infection of sclerotia of S.

在没有杀菌剂存在的情况下，这些突变菌株的转代培养后代和感染核盘菌菌核后产生的分生孢子后代仍具有抗性。

The comparison test of this new methodwith spray inoculation method was conducted. The results showed the former method could increase the incidence ofdisease and uniformity than the latter one. Used cotyledon-brushing with conidial suspension and fungicide foliarspraying method, the EC 50 values of hexaconazole, myclobutanil, triadimefon, thiophanate-methyl and chlorotha lonil to Sphaerotheca fuliginea treated in different time after inoculation were determined; the results showed that 96 h was better time for disease severity evaluating.

比较了白粉病菌分生孢子悬浮液涂抹法和喷雾法接种黄瓜幼苗子叶的效果，结果表明，涂抹法发病率高，均匀度更好；测定了接菌后不同时间施药，白粉病菌对己唑醇、腈菌唑、三唑酮、甲基硫菌灵和百菌清等 5 种杀菌剂的敏感性，结果表明，接菌后 96h 施药较为敏感，测得的 EC 50 较小。
