农药防治害虫虽可确保作物生产的目的,但长期大量使用农药,导致害虫与天敌生态的不平衡及害虫产生抗药性,进而依赖一种又一种的新农药,台湾对小菜蛾的防治农药多达38种,农民甚至以十几种农药混合使用,这样,越喷越多,越喷越杂,新开发的农药几乎来不及应付新衍生的小菜蛾抗药品种,更严重的是污染环境危及人类健康。

Pesticide control pest although the purpose of crop production can be ensured, but long-term use of pesticides, leading to ecological balance of pests and natural enemies and pest resistance, and then rely on one after another new pesticides, Taiwan’s diamondback moth prevention and control of pesticides and more Up to 38 species. Peasants even use more than a dozen kinds of pesticides. In this way, the more they spray and the more they are sprayed, the newly developed pesticides are almost too late to cope with the newly-derived diamondback moth resistant varieties. The more serious problem is that the environment is endangered by humans health.
