农药是一种重要的农业生产资料,主要分为化学农药(人工合成农药)、生物源农药(又分为动植物源农药和微生物源农药)和矿物源农药(主要有硫制剂、铜制剂等)。农药作为植物保护的主要手段之一,到目前为止仍然在农业生产上扮演着重要的角色。因此,如何科学合理地加以利用,使其发挥出应有的作用,并将其不利的方面降到最低,已成为摆在我们面前的一项重要课题。

Therefore, how to utilize it scientifically and reasonably, make it play its proper role and minimize its adverse aspects has become an important issue before us.
