生物制剂对水稻穗颈瘟防治效果试验研究

Analysis on Control Efficiency of Biological Agents on Neck Blast

为了筛选出防治水稻穗颈瘟的优良生物制剂,于2010年对生产上常用的化学药剂富士一号和生物药剂春雷霉素进行了防治水稻穗颈瘟的田间试验。结果表明,春雷霉素与富士一号处理的水稻病穗率及病情指数明显低于对照,春雷霉素处理的水稻病穗率及病情指数与富士一号处理间没有明显差异。

The field testing were made which using Isoprothiolane and Kasugamycin to control neck blast in 2010, that in order to select the better biological agents, the results indicated that the diseased panicle rate and disease index were obviously lower than contrast： by using Isoprothiolane and Kasugamycin, and there were not significantly different between Isoprothiolane and Kasugamycin on the diseased panicle rate and disease index.
