Abstract

The invention discloses a herbicide containing plant-derived nonanoic acid as well as a preparation method and application of the herbicide. The herbicide comprises the following components in percentage by weight: 20-50% of nonanoic acid, 1-10% of an emulsifier, 0.1-1% of a preservative, 1-10% of a penetrant, 0-10% of an antifreezing agent, 0-20% of a synergist, 0-5% of a thickener, 0-50% of a solvent and the balance of water. The herbicide disclosed by the invention is applied to non-cultivated land, orchards, forest land and crops before and after stubble, has the advantages of quick effect, wide weeding range, low residue, low toxicity, safety, environmental friendliness and the like, has great application and popularization value on organic crops, and is a novel biogenic herbicide product.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide containing botanical nonanoic acid, a preparation method and application thereof. Background technique [0002] Weeds are one of the main factors leading to crop yield reduction, and the area of ​​land damaged by weeds in China exceeds 73 million hm all the year round 2 , The direct economic loss exceeded 90 billion yuan. Weed control is one of the major challenges faced in agro-ecosystems and urban lawn management. Chemical herbicides occupy a dominant position in today's weed control because of their rapid action, significant effect, and labor-saving and time-saving characteristics. In recent years, the use of herbicides in agricultural production has become more and more extensive. The proportion of herbicides in the world's pesticide sales has exceeded 60%. Most of these herbicides are chemically synthesized high-efficiency or even super-efficient herbicides....
