Abstract

The invention relates to a bioherbicide composition and application thereof and belongs to the field of agricultural chemicals. The bioherbicide composition is missible oil, wettable powder, emulsion in water and water dispersible granules prepared from active ingredients including nonanoic acid and acetic acid, minor ingredients including a solvent, a carrier and a surfactant as well as other additives. By weight, the active ingredients account for 10-97% of the bioherbicide composition, the surfactant accounts for 1-8% of the bioherbicide composition, and the carrier and the other additives account for 2-80% of the bioherbicide composition. The bioherbicide composition can be used for directed spraying of urban courtyards and crop fields to control and kill gramineae, cyperaceae and broadleaf weeds and is wide in weeding spectrum, quick to act, high in control efficiency, safe and the like.

Description

technical field [0001] The invention relates to a herbicide, in particular to a biological source herbicide composition, and belongs to the field of agricultural chemicals. Background technique [0002] Weed control is one of the major challenges faced in agro-ecosystems and yard and lawn management. Chemical herbicides play a dominant role in weed control because of their rapid action, remarkable effect and labor-saving and time-saving characteristics. However, due to improper use, droplet drift, leaching, and liquid volatilization, chemical herbicides not only seriously affect the growth and development of crops, but also cause problems such as residual poisons and pesticides, polluted water sources, and pesticide residues in agricultural products. Compared with chemical herbicides, biological herbicides have the advantages of easy natural degradation, high environmental compatibility, and relative safety to target organisms, especially the herbicidal active substances de...
