近两年全国每年因鼠害造成的粮食作物田间损失达30～40亿公斤。其原因是治鼠不当,温氟乙酸钠,氟乙酰胺等剧毒农药的使用,药杀了大量鼠类天敌,破坏了自然生态平衡;加之近几年天气干旱,有利于鼠类繁殖,给农业生产带来严重损失。 消灭老鼠,必须坚持“预防为主,综合防治”的方针应选用灭鼠效果高,毒性小,污染轻的灭鼠方法,以保护天敌,控制害鼠的回升。 一、防治农田害鼠: 1.敌鼠钠盐毒饵:敌鼠钠盐对人畜低毒,对鼠
In the past two years, the annual loss of food crops caused by rodent pests in the country has reached 3 to 4 billion kilograms. The reason is the improper treatment of rats, warm fluoride sodium acetate, fluoroacetamide and other highly toxic pesticides use, killing a large number of natural enemies of murine, undermining the natural ecological balance; combined with the weather in recent years, drought, is conducive to the breeding of mice to give Agricultural production has caused serious losses. Eradication of rats, we must adhere to the “prevention first, comprehensive prevention and treatment,” the principle should be used rodent control effect, toxicity, light pollution rodent control methods to protect natural enemies, control the rat recovery. First, the prevention and treatment of pests in farmland: 1. The enemy of sodium poison bait: the enemy of the sodium salt of low toxicity to humans and animals, the mouse
