Abstract

The invention discloses a microbial herbicide and relates to the technical field of pesticides. The microbial herbicide comprises components in parts by weight as follows: 10-30 parts of cup fungi, 10-20 parts of pseudomonas pseudoacaligenes, 5-10 parts of citrobacter, 3-7 parts of fusarium, 1-5 parts of entyloma, 15-25 parts of sclerotinia sclerotiorum, 3-10 parts of achromobacter and 15-25 parts of halobacterium. The microbial herbicide is prepared from microorganisms such as cup fungi, pseudomonas pseudoacaligenes, citrobacter, fusarium, entyloma, sclerotinia sclerotiorum and the like and has the advantages of high selectivity, safety for non-target organisms and mammal animals, good environment compatibility, few development cost, novel chemical structure and unique action mode by optimizing the proportion of the components.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a microbial herbicide. Background technique [0002] According to the survey, there are more than 30,000 species of weeds in the world, of which about 1,800 species can cause serious economic losses. It is estimated that crops around the world lose an average of 12% of their potential yield each year due to weeds. Human beings fight against weeds, the oldest method is artificial weeding or weeding, these two methods not only consume a lot of labor and energy, but also the effect is not ideal. The chemical weeding method is convenient, effective and economical, and has become an indispensable part of modern agricultural technology. [0003] However, chemical herbicides are destructive to the environment, not easy to degrade, and easy to remain, and cause great harm to humans and animals. In view of the above problems, herbicides need to be continuously developed and improved....
