蔗田杂草是影响甘蔗产量的主要因素之一。本实验研究了55%2甲4氯·莠灭净·敌草隆可湿性粉剂对蔗田阔叶和禾本科杂草的防治效果,以明确其最佳使用剂量。结果表明,有效成分含量1237.5-1732.5g/hm2,药后30d,对蔗田各主要杂草和总草的株防效均在85%以上;药后45d,对各主要杂草和总草的株防效仍高于80%,鲜重防效在87%以上。对甘蔗安全、产量无不良影响。见效快、综合防效高、持效期长、杀草谱广等优点,使其宜在大田推广应用,生产上推荐用量为有效成分含量1237.5-1732.5g/hm2。
Cane field weed is one of the main factors affecting the yield of sugarcane. In this experiment, 55% 2 A 4 chloro-ametryn diuron WP on the control of broad-leaved and gramineous weeds in sugarcane field to determine the best dose. The results showed that the control effect of all the main weeds and the total grasses was more than 85% after 1237.5-1732.5 g / hm2 active ingredient and 30 d after the treatment. After 45 d, the control effect on the main weeds and total grass Plant control effect is still above 80%, fresh weight control effect in more than 87%. No adverse effects on sugar cane yield and yield. Quick effect, high comprehensive control effect, long holding time and broad spectrum of killing herb so as to promote its application in the field. The recommended dosage for production is 1237.5-1732.5 g / hm2.
