Abstract

The invention relates to a biogenic synergistic compound herbicide containing n-nonanoic acid and a preparation method thereof. According to the prepared biogenic synergistic compound herbicide, eucalyptus oil and n-nonanoic acid serve as main active ingredients, and a mass ratio of the eucalyptus oil to n-nonanoic acid is equal to (1:10) to (10:1). The herbicide, prepared from the main active ingredients with auxiliaries, can be prepared in the forms of missible oil, a micro-emulsion and an emulsion in water. As a novel biogenic herbicidal product, the biogenic synergistic compound herbicide has a quite high field controlling and eliminating effect on gramineous weeds and broadleaf weeds, and has high application and promotion value in the aspect of organic crops.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and specifically relates to a nonanoic acid-containing biosource synergistic compound herbicide and a preparation method thereof. Background technique [0002] The widespread use of chemical pesticides has played a huge role in ensuring high and stable crop yields. However, the long-term use of chemical pesticides has also brought many disadvantages, such as environmental pollution, direct poisoning of non-target organisms, and resistance of harmful organisms. In recent years, with the development of integrated pest management (IPM) theory, the implementation of human sustainable development strategy and the improvement of human health and environmental safety requirements, environmental compatibility, safety, high efficiency, low toxicity and low residue and The research and development of economical and easy-to-use bio-sourced pesticides are increasingly being questioned by people.
