Indigenous Methods of Plant Diseases and Pests Control

植物病虫害防治是农业生产的重要环节，但商品化学药剂的大量使用不仅危害生态环境，也影响农产品的品质和质量。植物病虫害防治土方法是指在人们长期农业生产实践中发现并流传下来的具有实际效果而不使用商品药剂防治植物病虫害的方法。在这些土方法中，有的就地取材或经过简单处理制成土农药，有的是利用天敌或生物防治，有的是利用病虫的生活习性进行物理防治，有的通过改变植物生长环境进行防治。本文梳理总结了植物病虫害防治的一些土方法，可为减少化学药剂的使用、促进农产品安全和生态环境保护提供参考。
Plant diseases and pests control is one of the important factors in agricultural production. However, the massive use of commercial chemicals not only destroys the ecological environment, but also re-duces the quality of agricultural products. The indigenous methods of plant diseases and pests control are found and handed down in people’s long-term agricultural production practice, which have practical effects to control plant diseases and pests without using commercial chemicals. In these indigenous control methods, some are to use local materials or be turned into pesticides after simple treatments to make indigenous pesticides, some are to use natural enemies or biological control, some are to use the living habits of diseases and insects for physical control, and some are to change the growth environment of the plant. This paper summarized some indigenous control methods of plant diseases and pests to provide references for reducing the use of chemicals and promoting the safety of agricultural products and ecological protection.
