通过60g/L五氟·氰氟草油SC(稻喜)不同用水量的田间除草药效试验,明确其对水稻田杂草的防治效果、最佳用水量。结果表明,60g/L五氟·氰氟草油SC(稻喜)100ml/667m2,50kg用水量药后15d防效最好,总株防效达到86.95%,但各处理的小区总株防效在5%水平和1%水平差异均不显著;40kg用水量处理的小区在药后30d对这两种杂草的株防效最好,均为100.00%,小区总株防效与鲜重防效均为100.00%,与其余各小区处理的结果在1%水平差异极显著。推荐用水量为每667m245kg。各处理未见对作物生长产生不良影响,安全无药害。
Through the field herbicidal efficacy test of 60g / L pentafluorocyanurate SC with different water consumption, the effect of controlling weeds in paddy field and the optimum water consumption were clarified. The results showed that the control effect of 60g / L pentafluorocyanurate SC (Inhi) 100ml / 667m2 and 50kg water for 15d was the best, and the total control efficiency reached 86.95%. However, At 5% level and 1% level, the difference was not significant. In 40-kg water-treated plots, the control effect on the two weeds was 100.00% Efficacy of 100.00%, and the rest of the district to deal with the results at the level of 1% difference was significant. The recommended water consumption per 667m245kg. No adverse effects on crop growth were found in all treatments, and no harm was harmed.
