我国植物病害生物防治的现状及发展策略

植物病害生物防治是利用有益微生物和微生物代谢产物对农作物病害进行有效防治的技术与方法,本文介绍了我国在生物农药资源筛选评价体系、基因工程、发酵代谢工程等方面取得的可喜进展和研制出的多种高效植物病害生物防治药物;提出未来5～10年,植物病害生物防治学科领域主要工作是集成现代科学技术,进一步明确不同生防因子控制植物病害的分子机制,加强国际合作与交流,建立有关领域共享技术的合作研究平台,提高植物病害生物防治的基础与应用基础研究水平;指出植物病害的生物防治是保障食品和环境安全的重要措施,对国家可持续农业的健康发展具有重大的战略意义。

Current status and development strategy for biological control of plant diseases in China

Biological control of plant diseases is the effective techniques and methods using beneficial microorganisms and microbial metabolites against crop diseases. This article describes the gratifying progress in resources of the biological pesticide screening and evaluation system, genetic engineering, fermentation and metabolic engineering in China, and a variety of effective biological pesticides against plant diseases have been developed. In the next 5 to 10 years, the main areas of biological control is to integrate modern science and technology, further clarify the molecular mechanisms of different biological control of plant diseases, enhance international cooperation and communication. It is necessary to establish the technical cooperation platform and improve the basis and application research in biological control of plant diseases. Biological control of plant diseases is the important measures in food and environmental safety, which have great strategic significance in national sustainable agriculture.
