| 摘 要： | 为筛选出高粱田除草效果好、价格适宜的苗后茎叶除草剂。在高粱苗后6叶期采用茎叶施药进行田间药效试验,比较了6种茎叶除草剂的药效、安全性及成本。结果表明,6种除草剂对高粱均无明显药害;38%莠去津SC 1 500mL/hm 2+增效剂450mL/hm 2对高粱田难防禾本科杂草有特效,株防效和鲜重防效分别为91.41%和93.54%,成本为330元/hm 2;38%莠去津SC 3 000mL/hm 2+50%二氯喹啉酸WP 750g/hm 2+57% 2,4-滴丁酯EC 450mL/hm 2对阔叶杂草防效显著,且对杂草的综合防除效果最好,鲜重防效和株防效分别为92.76%和91.52%,成本为300元/hm 2。高粱田苗后防除一年生禾本科杂草可选用38%莠去津SC 1 500mL/hm 2+增效剂450mL/hm 2;防除一年生禾本科和阔叶杂草可选用38%莠去津SC 3 000mL/hm 2+50%二氯喹啉酸WP 750g/hm 2+57% 2,4-滴丁酯EC 450mL/hm 2。

| Abstract: | Our study was to select effective herbicides targeting on post emergence of sorghum stem and leaf treatment with a reasonable market value. This study compared six stem and leaf treatment herbicides of sorghum under field control. The field efficacy, safety and cost were carried out at sorghum seedings after 6 leaf stage by applications on stem and leaf treatment. The results showed that the six herbicides had no obvious damage to sorghum. 38% Atrazine SC 1500mL/hm 2+Enhancer 450mL/hm 2 had special effects to the gramineous weeds, strain control and fresh weight control effect was 91.41% and 93.54%, respectively, the cost was 330yuan/hm 2; 38% Atrazine SC 3000mL/hm 2+50% Quinclorac WP 750g/hm 2+57% 2,4-D butyl ester EC 450mL/hm 2 had significant effects to the broadleaf weeds, and the comprehensive control effects on weeds were the best, strain control and fresh weight control effect was 91.52% and 92.76%, respectively, and the cost was 300yuan/hm 2. 38% Atrazine SC 1500mL/hm 2+Enhancer 450mL/hm 2 was recommended to be used to control gramineous weeds. 38% Atrazine SC 3000mL/hm 2+50% Quinclorac WP 750g/hm 2+57% 2,4-D butyl ester EC 450mL/hm 2 was recommended to be used to control gramineous and broadleaf weeds. |
