Research review on herbicide activity of phytopathogeny mycotoxins

Mycotoxin with herbicide activity could be excreted by many plant pathogenic fungi. It can make weeds be albino and wilting, restrain the growth of weeds or kill weeds. Fermentation solution or crude toxins of many biocontrol agents to weeds also have weed controlling activity. The utilization of mycotoxin became one of the hot topics of researches on microbial herbicide in recent years. Different kinds of mycotoxin have different bioactivity, chemical structure, action site and mechanism and this could be a new approach for researchers to find out new herbicides. In this paper, the plant pathogenic mycotoxin as biocontrol agent was discussed in its herbicidal activity, control objects, mechanisms and biocontrol effect on weeds and the role for new herbicide development.
