以张杂谷5号为试材,研究了44%单嘧磺隆·扑灭津WP对杂交谷田杂草的防除效果。结果表明,该药剂对谷田杂草的防效高于50%扑灭津WP,其2 100 g/hm~2剂量处理在药后45 d对杂草的株防效达到84.8%,鲜重防效达到97.3%,与2 400g/hm~2剂量处理的防效无显著差异,且对谷子安全,与空白对照区相比增产33.59%,为各处理中最高,可作为防除谷田杂草的参考使用剂量。 Taking Zhangzhegu No.5 as experimental material, we studied the control effect of 44% monosulfuron-fenvastatin WP on weeds in hybrid field. The results showed that the control effect of the agent on weeds in the field was higher than that of 50% Fenjin WP, and the control effect on the weeds was 84.8% at the rate of 2 100 g / hm ~ 2 45 days after treatment. Reached 97.3%, which was no significant difference with the control effect of 2,400g / hm ~ 2 dose, and the yield was increased by 33.59% compared with the blank control area for the safety of millet, which was the highest in all treatments and could be used as reference for controlling weeds in valley dose.
