广灭灵与吡嘧磺隆等药剂混用防除直播稻田杂草研究

Study on the Weeding in Direct Seedling Paddy Fields with Mixed Supply of Guangmieling and Bimihuanglong

田间小区试验表明,36%广灭灵CS与多种农药混用对水稻直播田杂草有较好的防除效果。对鲤肠和田菁的防除效果达90%以上,对稗草和千金子的防除效果达90%以上。综合防除效果以亩用36%广灭灵CS35mL+10%吡嘧磺隆WP15g+50%二氯喹啉酸WP20g为最好。

The field experiment indicates that mixed supply of 36% Guangmieling CS with several other herbicides has good effect on the weeding in direct seedling paddy field. Specifically speaking, the weeding rate is more than 90 % on Eclipta prostrate and Sesbania cannabina, and more than 80% on Echinochloa crus-galli and Leptochloa chinensis. With regard to the integrated weeding effect,the best treatment is 36% Guangmieling CS 35 ml ＋ 10% Bimihuanglong WP 15 g ＋ 50% Erlvkuilinsuan WP 20 g per 666.7 m^2.
