摘要
通过几种除草剂在玉米苗后4～5叶期对田间杂草的药效试验结果表明,各处理药后20d的株防效和鲜重防效差异都不明显。按除草效果,宜选用制剂用量为38%莠去津SC1500mL/hm2+5%烟嘧磺隆OF1050mL/hm2或5%烟嘧磺隆OF1050mL/hm2+20%氯氟吡氧乙酸EC750mL/hm2,但从经济和安全的角度,宜选用5%烟嘧磺隆OF900mL/hm2+20%氯氟吡氧乙酸EC300mL/hm2。
Experiments were carried out on control effect of several herbicides to cornfield weeds in 4-leaf to 5-leaf of corn. Different treatments show little difference on plant control effect and fresh weight control effect 20 days after application. The mixture of 38% atrazine 1500 mL/ha and 5% nicosulfuron 1050 mL/ha and mixture of 5% nicosulfuron 1050 mL/ha and 20% fluroxypyr 750 mL/ha showed better control effect. Mixture of 5% nicosulfuron 900 mL/ha and 20% fluroxypyr 300 mL/ha was advised for its economics and safety.
