寒地水稻稻瘟病和褐变穗综合防治效果研究

Study on the control effect of Blast and Brown panicle disease in rice at cold area

为更有效的防治水稻稻瘟病和褐变穗,特进行此试验,结果表明,防治效果最好的药剂为2%加收米液+3.5%多抗霉素+25%咪鲜胺,并通过降低此类病害的发病率达到增产的目的,采用2%加收米液+3.5%多抗霉素+25%咪鲜胺的处理实际产量为658.9 kg/667 m^2,较空白对照增产10%。

The results showed that the best pesticide combination was 2% kasugamicin＋3.5% polyoxin＋25% prochloraz. The yield was 658.9 kg/667 m^2, increasing by 10% over control.
