Abstract

A botanical herbicide belongs to the technical field of herbicides. It consists of the following components by weight percentage: 2-6% of sycamore leaf extract, 2-6% of ginkgo fruit extract, 1-5% of garlic extract, 1-5% of Zanthoxylum bungeanum extract, dodecylbenzene Sodium sulfonate 2‑10%, the balance of water. The above-mentioned botanical herbicide has remarkable effect, is natural and environmentally friendly, has no toxic and side effects, has the effect of preventing and controlling various weeds in the field, has no effect on crops, and solves the current problem of herbicide resistance.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a botanical herbicide. Background technique [0002] As modern agricultural production puts forward higher requirements for the safe and reasonable use of herbicides, this requires enterprises to look forward, develop and innovate, and accelerate the development of efficient, safe, broad-spectrum, and environmentally friendly herbicide varieties that meet the actual needs of agriculture. Taking into account some small crops, injecting fresh vitality into the diversity of herbicide varieties. However, most herbicides in my country currently use chemical reagents, which are not environmentally friendly and have a great impact on the environment. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to design and provide a technical solution of a botanical herbicide. [0004] The plant-derived h...
