摘要
近年来,生物农药被寄予厚望,希图用它来代替化学农药.生物农药并非都是无毒无公害,我们应辩证地 看待化学农药.
In recent years, great expectations have been laid on biological pesticide, with the hope that it will replace chemical pesticide. However, not all biological pesticides are poisonless and harmless, so we should take a dialectical view towards biological pesticides.
