为了明确马唐新月弯孢的生防价值,更好地利用该菌开展生物防治,我们对其进行了分离纯化,利用其代谢产物进行除草活性测定,结果表明马唐新月弯孢代谢产物具有较强的生物活性,对所有供试植物种子均产生了根茎及鲜重的抑制作用,从除草剂的角度来说还表明该代谢产物在不同植物间存在一定的选择性。 In order to clarify the biocontrol value of Curvularia lunata and to make better use of the strain for biological control, we isolated and purified it, and determined the herbicidal activity using its metabolites. The results showed that the metabolites of Curculigo orchids had strong Biological activity of all the tested plant seeds have rhizome and fresh weight inhibition, from the perspective of the herbicide also showed that there is a certain selectivity of the metabolites in different plants.
