近年来国际上对植物保护有三种主张:一是主张化学防治(生产、使用高效低毒农药);二是提倡生物防治(开展以菌、以虫等的研究利用);三是主张采取化学、生物和耕作栽培制的综合防治法。化学、生物防治,在植物保护工作中都占有极其重要的地位,但也各有不足之处,故相辅相成的综合防治法得到多数赞同。
In recent years, there are three kinds of advocates for plant protection in the world: first, advocating chemical control (production and use of highly effective and low toxicity pesticides); second, promoting biological control (carrying out research on bacteria and insects); third, advocating the adoption of chemical, Integrated management of biological and tillage cultivation. Chemistry and biological control all play an extremely important role in the plant protection work, but each has its own shortcomings. Therefore, the comprehensive prevention and treatment law that is mutually reinforcing has been largely endorsed.
