吡唑醚菌酯·稻瘟灵防治水稻稻瘟病应用研究

Application of Pyraclostrobine·Isoprothiolaneto Prevent the Rice Blast

试验结果表明,用25%吡唑醚菌酯·稻瘟灵水乳剂有效成分225g/hm2防除水稻稻瘟,于水稻破口初喷雾处理,间隔7d左右第二次用药,对水稻稻瘟病有良好的防效,穗颈瘟的防效达75.6%,优于两对照单剂的防效,且对水稻安全。

25% Pyraclostrobine· Isoprothiolane EW was sprayed with 225g/hm2 to prevent and treat the rice blast during the rice break period. While 7 days later,it was sprayed again. This EW showed a very good and safe curative effect to rice blast,especially 75.6% to panicle blast,which is better than the other two contrast agents.
