长期以来,我国农田使用的杀鼠剂如磷化锌、氟乙酰胺(现已禁用)等毒性大,常用不但鼠拒食,而且引起二次中毒,不安全。近年各地应用抗凝血剂如敌鼠、溴敌隆、杀鼠迷等慢性药剂,杀灭农田害鼠,效果虽好,多死于洞内,群众见不到死鼠,误认灭鼠效果不好。因此,进一步筛选适合农田、果园、林地等使用高效低毒速效的杀鼠剂,是我们灭鼠研究工作中迫切需要解决的主要问题。 For a long time, the rodenticides used in farmlands in China such as zinc phosphide and fluoroacetamide (now banned) have great toxicity and are commonly used not only to refuse food but also to cause secondary poisoning, which is unsafe. In recent years, the application of anticoagulants such as anti-clot agents such as the enemy, bromadiolone, killing rats and other chronic agents, killing farm rats, although the effect is good, and more died in the hole, the crowd can not see the dead mice, rodent control mistaken results not good. Therefore, further screening suitable for farmland, orchard, woodland and other use of high efficiency and low toxicity quick-acting rodenticide, our rodent research urgently need to address the major issues.
