Abstract

The invention discloses a microbial herbicide and a preparation method thereof, and particularly relates to the technical field of microbial herbicides, and the microbial herbicide comprises the following components in percentage by weight: 10-25% of 1, 1 '-ethylene-2, 2'-bipyridyl dibromide, 30-45% of bacillus megatherium, 10-25% of persimmon spores, 15-25% of helminthosporium graminearum and 14-30% of trichoderma. By adding the bacillus megatherium, the bacillus megatherium has a very good effect of degrading organic phosphorus in soil, can improve the soil and can rot grass roots, the added persimmon spores can enable the prepared herbicide to prevent and control persimmon weeds in fields, and the added trichoderma can effectively inhibit soil-borne pathogenic fungi, so that the herbicide is safe and environment-friendly. The added helminthosporium graminearum can effectively inhibit the growth of barnyard grass, and the added 1, 1 '-ethylene-2, 2'-dipyridyl dibromide expands the application range of weeding.

Description

Technical field [0001] The present invention relates to the field of microbial herbicide technology, specifically to a microbial herbicide and a method of preparation thereof. Background [0002] Microbial herbicide is a new type of microbial herbicide that uses secondary metabolites produced by microorganisms, that is, plant toxins, for weed control. Microorganisms can produce many metabolites, which have the characteristics of structural and biological activity diversity and are easily biodegradable. Among these metabolites are the active substance component that makes the plant susceptible, produces spots or wilts, and this active substance component invades the host plant, makes it susceptible to disease, and destroys its cellular structure in order to achieve the purpose of controlling weeds. [0003] Microbial metabolites contain an active substance component that makes the plant susceptible, produces spots or wilts, and this active substance component invades the host plan...
