Abstract

The invention discloses a biological source herbicide, a preparation method and a use thereof. The active ingredient of the herbicide is pelargonic acid originated from animals and plants such as animal tallow, cypress, Rhus succedanea, geranium, tea seed and rapeseed. The herbicide comprises the following components: 5%-50% of pelargonic acid, 5%-20% of auxiliary agent, 5%-20% of anti-freezing agent, and 10%-60% of water. The herbicide is sterilant herbicide with quick action and broad spectrum activity, and can efficiently prevent and kill various broad leaved weeds and grassy weeds.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicide with nonanoic acid as an active ingredient, its preparation method and application. 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 causing environmental pollution, direct poisoning of non-target organisms, and easy resistance of pests. In recent years, with the implementation of the IPM theory, the development of sustainable development strategies and the improvement of human health requirements, the research and development of bio-sourced pesticides with good environmental compatibility, safety, low toxicity, low residue and economy have become increasingly popular. attention. [0003] Biological pesticides are pesticides that use biologically active substances or their specific ...
