摘　　要：Ectomycorrhizae (ECM) is becoming the research hotspot because it can improve plant nutrientcycling and storage and strengthen plant resistance to adversity and disease. It is well known that ECMcan enhance plant resistance to soil-borne and stem diseases. The mechanisms mainly include: plant tenderroots will be protected well by sheath; ECM can facilitate uptake and transport capacity of nutrition andwater to roots and increase plants vigor; ECM can control or block pathogens to invade trees; ECM canactivate resistance-related enzymes of the hosts; it also can form rhizosphere microbial colony and establishroot-rhizosphere micro-ecological environment. So mycorrhizal technology has become one of the mostimportant methods of ecological control and biological control of plant diseases. This paper summarizesthe application and development of ECM in forest disease control and also raises some ideas on theirtheory and application researches in the future.Ectomycorrhizae (ECM) is becoming the research hotspot because it can improve plant nutrientcycling and storage and strengthen plant resistance to adversity and disease.
