Mirobial source herbicide and its preparing method and use

Abstract

The invention relates to a new kind of herbicide with a effective ingredient which is primarily extracted from the metabolic of Streptomyces Lavendulae. Firstly the active herbicide ingredient is separated from the cultivated microorganism of the (Streptomyces Lavendulae) CGMCC No.1368. Then the final herbicide is formed with the selected carrier and auxiliary agent. Such herbicide is advanced inthe low dosage, broad-spectrum effect and safety to the environment. It could be a high efficient herbicide both in the paddy field and glebe.

Description

A microbial herbicide, its preparation method and application technical field The invention belongs to the field of pesticides, and in particular relates to a herbicide with microbial metabolites as active ingredients, a preparation method thereof, and an application of the herbicide. Background technique Since chemical herbicides began to be used in the 1940s, chemical herbicides have become an important means of weeding farmland to reduce labor intensity and improve work efficiency. At present, chemical herbicides occupy most of the market, but with the continuous application of chemical herbicides , has clearly exposed its disadvantages. First, the herbicide droplet drift, the volatilization of the liquid, the selectivity is not ideal, and the harm of the degradation product causes the phytotoxicity of the crops; secondly, the repeated use of the herbicide causes the population of drug-resistant weeds to increase. , The emergence of herbicide-resistant weeds and the inc...

Since chemical herbicides began to be used in the 1940s, chemical herbicides have become an important means of weeding farmland to reduce labor intensity and improve work efficiency. At present, chemical herbicides occupy most of the market, but with the continuous application of chemical herbicides , has clearly exposed its disadvantages. First, the herbicide droplet drift, the volatilization of the liquid, the selectivity is not ideal, and the harm of the degradation product causes the phytotoxicity of the crops; secondly, the repeated use of the herbicide causes the population of drug-resistant weeds to increase. , the emergence of herbicide-resistant weeds and the increasingly serious environmental pollution, making the development of new herbicides more difficult and more expensive
