浅议生物农药取代化学农药

近年来，“生物农药”已经有了发展，但也存在一些问题，把活性成分为化学物质的植物农药，抗生素农药等视为“生物农药”，从实用角度看，似为不妥；泛透“生物农药”安全，无公害的，科学依据不足；世界环发大会（1992）提出，到2000年，“生物农药”用量要占农药60%的口号已化为泡影，因为它的依据不足，仅为一个政治号召。

A Brief Comment on Biopesticide

In recent years, biopesticides have got good development and have become a component of pesticides but there are some questions needed to discussion. From the view of practice, it seems no reasonable classing botanic pesticide and antibiotic pesticide as biopesticide, because of their active components are chemicals; It is not scientific that declaring biopesticides are coming from nature and hence they are safe and have not contamination; In the world environment and development conference (1992), it was suggested that the usage of biopesticide should have reached 60% of the pesticide by 2000, but it was failed. The cause of the failure was discussed.
