| 中文摘要: |
| 经黄瓜霜霉病孢子囊萌发抑制试验明确,芽孢杆菌菌株Z-X-3、Z-X-10对黄瓜霜霉病菌有较强拮抗作用。离体叶片法和温室防病试验表明,两菌株对黄瓜霜霉病有较好的防治效果,相对保护效果分别达46.42％、41.55％;治疗效果分别达46.30％、44.44％,高于农药克霜氰的31.81％、37.03％。 |
| 英文摘要: |
| Twostainsi Z-X-3 and Z-X-10, of Bacillus with strong antagonistic activity against Pseudoperonospora cubensis (Berk, et Curt.) Rostov, were selected by using an apore-germination method. The control effects of Z-X-3, Z-X-10 strains on downy mildew of cucumber were tested on detached-leaves and in greenhouse. The relative immunisation efficiencies of Z-X-3 and Z-X-10 were 46.42% and 41.55%, and the control effects were 46.30% and 44.44%, respectively. They were higher than those of chemical fungicide cymoxanil and mancozb with 31.81 % and 37.03% , respectively. |
