| 摘 要： | 在室内条件下，中嗪霉素对小麦纹枯病菌具有强烈的抑制作用，其毒力回归方程为Y=0．7965X一4．3424（R2=O．9938），药剂的EC50值为0．4366±0．5130ug（a.i）／mL。盆栽试验结果表明，100ug（a．i．）／mL申嗪霉素对小麦纹枯病的防治效果最好，防效达到71．5％，显著高于100g．g（a．i．）／mL井冈霉素对小麦纹枯病的防治效果。10 ug（a．i.）／mL和50ug（a．i.）／mI，中嗪霉素对小麦纹枯病的防治效果次之，分别为44．4％和61．3％。 |

| Abstract: | Shenqinmycin has a strong inhibitory effect on Rhizoctonia cerealis in vitro. regression equation of this antibiotics was Y = 0. 796 5X- 4. 342 4 （R2 = 0. 993 8）, EC50 The virulent =0. 436 6± 0. 513 0ug/mL. 100 ug（a. i. ）/ mL of Shenqinmycin was the best dosage against wheat sheath blight （effectiveness rate was 71.5 %）. The effect of Shenqinmycin was significantly higher than the control effect of 100ug（a. i. ）/mL Jinggangmycin in pot experiment. Efficiency of 10 and 50ug（ai）/ mL Shenqinmycin against wheat disease was 44. 4% and 61.3% ,respectively. |
