为提高农田灭鼠效果,自1983年以来,通过反复试验和大面积示范,在药物灭鼠技术上进行了如下三项改进: 一、改慢性药剂为急性药剂:前几年,我市农田灭鼠推广的是0.3～0.5%敌鼠钠盐小麦毒饵,效果不理想,且大面积使用不经济。近几年来,通过试验示范,改用急性灭鼠剂2～3%磷化锌小麦毒饵和0.5%溴代毒鼠磷小麦毒饵灭鼠,灭鼠率达90.00～96.36%,平均93.18%,比敌鼠钠盐灭效提高4.5～12.23%,且省工省料,经济效益高。
In order to improve the farmland rodent control effect, since 1983, through repeated experiments and large-scale demonstration, the following three improvements have been made in the technology of drug rodent control: First, to change the chronic medicament into an acute medicament: A few years ago, Promote the mouse is 0.3 to 0.5% of the enemy mouse sodium salt bait, the effect is not satisfactory, and large-scale use of uneconomical. In recent years, through experimental demonstration, instead of using acute rodenticides 2-3% zinc phosphide wheat bait and 0.5% brominated poisonous rat phosphorus wheat bait rodent control rate of 90.00 ~ 96.36%, an average of 93.18%, than Enemy sodium salt to improve the effectiveness of 4.5 to 12.23%, and save labor and material, high economic efficiency.
