摘要
田间试验结果显示：２３％宝穗胶悬剂对水稻纹枯病有较好的防治效果。在杂交稻上应用 １０—２０ｍｌ／６６７ｍ２，其防效在８０％～ ９５％，且持效期长达１个月，显著优于目前大面积使用的井冈霉素等药剂。试验还表明：在粳稻上最佳应用适期在粳稻 抽穗前２０天。
The result of field experiments showed that 23% Pulsor had good control effects agaist rice sheath blight disease caused by Rhizocotoni solani. Using 10-20ml/667m2 of 23% pulsor agaist rice sheath blight disease in hybrid rice, the control effects were up to 80-95% and lasted for more than 30 days. The control effects were better than that of Jinggangmycin which widely used. The experiment still showed that the optimum application timing was 20 days before heading stage in japonica rice.
