摘  要：
采用田间小区试验方法,研究了18%二甲戊灵·异恶草松可湿性粉剂防除稻田杂草药效试验。结果表明在水稻移栽5～7d,缓苗后施用剂量为有效成份0.1755～0.351kg/hm2,对稗草的防效幅度为95.8%～100%,对各种阔叶杂草的防效幅度为80.0%～100%,对莎草科杂草的防效幅度为86.7%～100%,对各种杂草的鲜重抑制效果为93.6%～99.9%。杀草谱广,持效期长,而且对水稻生长发育无不良影响,增产幅度为18.8%～37.5%。

摘  要：
By field trials, control effect of 18% pendimethalin + clomazone WP against weeds in transplanted rice was studied. The results showed that excellent weed control performance was achieved when 18% pendimethalin + clomazone WP was applied at 5 to 7 days after transplanting and with the dosage of 0.175 5 to 0.351 kg/hm2. The average control effect reached 95.8% to 100% against barnyard grass, 80.0% to 100% against all kinds of broadleaf, and 86.7% to 100% against sedge. The inhibition effect to weed fresh weight reached 93.6% to 99.9%. 18% Pendimethalin + clomazone WP is a herbicide with a wide spectrum and a persistent control effect. The yield increased in all treatments and its increase rate was 18.8% to 37.5%.
