| 中文摘要: |
| 井岗霉素防治早稻纹枯病，其控病效果与施药时病情基数和控病时间有关，早稻纹枯病的防治以施药１～２次为宜，一次施药适期为孕穗至抽穗期，其控病效果为６３％～７４％，两次施药适期为孕穗至灌浆期，控病效果为８６％～９３％，不同施药措施对纹枯病控制效果与经济效益都有显著影响，用药次数一般不必超过两次。 |
| 英文摘要: |
| Quantitative studies on the effect of Jinggangmycin on sheath blight of early rice showed that the effectiveness of normal dosage spraying was related to the disease index and spraying timing.The ap- propriate period for spraying was from booting to kernel stage. The proper time for one spray was at booting and heading stages,and the controling effect was 63%～74%. The proper time for two sprays should be at booting to kernel watery stage,and the controling effect was 86%～93%. Spraying more than twice seemed to be unnecessary. Different ways of spraying influenced much upon controling effect and economical benefit. |
