摘要
木霉是植物病害生物防治中应用和研究非常广泛的一类生防真菌。本文阐述了木霉在多种植物病害防治上的应用及防治效果,并概括了木霉在生防过程中对植物病原物的生防机制,包括竞争、重寄生、抗生作用等,以及木霉与植物互作中对植物促生和诱导植物抗性的机制。目前,世界上含木霉的商品化制剂已超过250种,在不同国家地区都取得了良好的防治效果,更多的优秀生防木霉菌株也在通过野生菌株筛选或遗传改良等方式开发。木霉生物防治及机制研究对推广生物防治和减少化学农药有重要意义。
Trichoderma spp. are widely studied biological control agents(BCA) and have been used worldwide for plant disease control. The application and control efficiency of Trichoderma in control of plant diseases was reviewed in this paper. The multiple biocontrol mechanisms of Trichoderma against pathogens, including competition, mycoparasitism and antifungal activity, as well as the interaction with plant(plant growth promotion and induced resistance), were summarized. More than 250 Trichoderma-based bio-products have been commercialized and successfully used in different area of the world, exploration of more potential Trichoderma isolates by screening or genetic improvement are still processing. The researches of Trichoderma-based biocontrol and the mechanism have outstanding contributions to the application of biocontrol and the reduction of chemical fungicide use.
