利用植物病原真菌除草的研究进展

Research Progress of Utilizing Plant Pathogenic Fungi to Control the Weed

随着病虫草害的发生,化学药剂大量使用,带来了一系列的环境和生态问题,如抗药杂草种群的增加、土壤板结和水体污染等,严重影响了农业生态的可持续发展。植物病原真菌是引起植物发生病害的一类微生物,但对杂草而言,却是一类可开发利用的潜在资源。植物病原真菌侵染杂草的同时,分泌毒素抑制杂草生长或直接导致杂草死亡。对利用植物病原真菌防除杂草的研究进行了综述,以期为其进一步研究作理论基础。

Along with the damaging of disease,insect and weed,the wide use of chemical pesticides came with a series of environment problems,such as the increase of resistant weeds population,soil crust,water pollution,and so on.This has disadvantage influence on the agriculture ecology sustainable development.Plant pathogenic fungi usually cause the plant disease,but to the weed,it is a kind of potential and utilizable resources.Plant pathogenic fungi infects the weed,at the same time,it secrets the toxin which can inhibit weeds growth or kill it directly.With a prospect to pave the further research,the paper is a summary about the research progress of utilizing plant pathogenic fungi to control the weed.
