1979年8月上旬,我县棉区红蜘蛛暴发,造成红叶,但未脱落,当时东津公社联盟大队几个生产队因农药接济不上,采用碳酸氢铵兑水喷雾,将溶液喷于棉叶背面,每担水掺入碳铵1.5斤(折合70—80倍),待其溶解后,立即抢晴喷雾,三天后检查,幼螨死亡率80%以上,接近三氯杀螨砜的防治效果,而且棉叶颜色好转;五天后,遭受红蜘蛛为害的棉叶恢复生机,颜色青绿。以后其他生产队也相继仿效,都取得同样的治螨效果。
In early August 1979, cotton spider moths broke out in our county, causing the leaves to fall but did not fall off. At that time, several production teams of the Tungjin Commune Brigade were unable to access the pesticides because of pesticides. A bicarbonate watered spray was used to spray the solution on cotton On the back of the leaves, 1.5 kg of ammonium bicarbonate (equivalent to 70-80 times) is mixed with each water, and immediately after it is dissolved, it is checked for clear spray. After three days, the mortality of young mites is over 80%, which is close to the control of dicofol Effect, and the color of the cotton leaf improved; five days later, the cotton leaf damaged by the red spider resumed its life, the color green. After other production teams have also followed suit, have achieved the same effect of governance mites.
