| 摘 要： | 筛选了20%前胡微粉水悬浮剂的最佳配方,并对其稻瘟病防治效果进行了研究。20%前胡微粉水悬浮剂的最佳配方为：前胡微粉20%,润湿分散剂（NNO＋FS3 000）5%,增稠剂黄原酸胶0.15%、抗冻剂乙二醇1%,稳定剂有机膨润土0.5%,水补足至体积的100%。盆栽试验结果表明,20%前胡微粉水悬浮剂在100～400倍液的剂量下对稻瘟病的防治效果可达74.22%～84.99%。田间试验结果表明,20%前胡微粉水悬浮剂在100～200倍液剂量下对稻瘟病的防治效果最好,为76.66%～76.88%,防治效果与稻瘟病常规化学防治药剂三环唑相当,显示了良好的应用前景。

| Abstract: | Formulation of 20% Radix peucedani SC was screened for its control effect on rice blast in this experiment. Optimum formulation of 20% Radix peucedani SC included 20% Radix peucedani, 5% NNO＋FA3000, 0.15% XG, 1% glycol, 0.5% organobentonite and water.Indoor assay indicated that the optimal control effect was 74.22%～84.99%, using 100～400×diluent of 20% Radix peucedani SC. Field assay indicated that the control effect of 100～200 ×diluent of 20% Radix peucedani SC was 76.66%～76.88%. The results showed that 20% Radix peucedani SC has a favorable application prospect for rice blast control. |
