Weed killer made of biological materials and preparation process

Abstract

The invention relates to a weed killer made of biological materials and a preparation process. The weed killer is characterized by comprising the following components in parts by mass: 15-25 parts of artemisia scoparia, 10-15 parts of chromolaena odorata, 10-20 parts of coptis chinensis, 10-20 parts of melia azedarach bark, 15-25 parts of angled bittersweet, 10-20 parts of organic silicon, 20-30 parts of lemon, 10-20 parts of green plum and 1-3 parts of penetrating agent. The weed killer and the preparation process have the advantages that the obtaining of adopted raw materials is easy, the cost of the raw materials is low, and because the adopted raw materials are non-toxic and harmless, the prepared weed killer is also non-toxic and harmless; the weed killer is good in effect and wide in weed killing spectrum and is less influenced by weather when in weed killing, so that the purposes of reducing the pesticide application amount, prolonging the effect lasting period, reducing the environmental pollution and reducing the cost are achieved; the preparation form is good; by effect comparison, the weed killer made of biological materials has less pollution to the environment, and can guarantee the safety of crops effectively, so that no harm caused to persons and animals due to absorption of chemical substances in the crops can be guaranteed; and the use amount of pesticide can be reduced.

Description

technical field [0001] The invention relates to the technical field of herbicide production, in particular to a formulation and a production process of a herbicide produced from biological materials. Background technique [0002] Herbicides, also known as herbicides, refer to agents that can completely or selectively kill weeds. Sodium chlorate, borax, arsenic acid, trichloroacetic acid have a deadly effect on any kind of vegetation, but because of their residual effects, they should not be used in the field. Selective herbicides, especially derivatives of nitrophenols, chlorophenols, and carbamic acids, are mostly effective. [0003] There are many kinds of herbicides, such as paraquat, glyphosate, and acetochlor. The ingredients of each are slightly different, but the main ingredients are uranium chlorate, shed sand, limestone, and trichloroacetic acid. But here These ingredients have a deadly effect on any kind of plant, but because these have residual effects, they can...
