棉蚜是棉花的主要害虫,从棉苗出土就群集叶背及嫩茎上刺吸汁液,造成卷叶枯茎,生长停滞。蕾期受害,花蕾过早脱落,严重影响棉花产量的提高。 1980年我们用江苏生产的3％呋喃丹微粒粉剂拌棉种,防治棉蚜等害虫,效果良好。我们选择30亩棉田,在棉花播种时,进行药剂拌种。拌种时,先将棉种浸入“三开一凉”的水中泡半小时,然后将棉种捞出晾干。每20斤干棉籽拌入3％呋哺丹微粒剂2斤,然后播种。棉苗出土后1个星期,进行第一次田间调查,用呋喃丹拌种的,控制蚜虫效果达100％。从棉 Cotton aphid is the main pest of cotton, unearthed from the cotton seedlings on the back of the cluster and the tender stem sucking juice, resulting in curly leaf stems, growth stagnation. Bud stage victims, buds off prematurely, seriously affecting the yield of cotton. In 1980, we used 3% carbofuran powder mixed with cotton seed produced in Jiangsu Province to prevent and control pests such as cotton aphid and got good results. We choose 30 acres of cotton fields, cotton sowing, pharmaceutical dressing. Seed dressing, the first cotton seed soaked in “three open a cool” water soak for half an hour, then remove the cotton seed to dry. Each 20 kg of dry cottonseed mixed 3% furosemide granules 2 pounds, and then sown. One week after the cotton seedlings were excavated, the first field survey was conducted, and the fumarate seed dressing was used to control aphid effects up to 100%. From cotton
