Embodiment 1

[0020] A plant-derived biological herbicide, the raw materials of which are: 33 parts of chamaejasme, 50 parts of podophyllum, 25 parts of baebu, 43 parts of atractylodes rhizome, 3 parts of sodium secondary alkylsulfonate, and 1.7 parts of triethanolamine;

[0021] The preparation method is:

[0022] (1) Mix chamaejasma, podophyllum, herb and atractylodes, add 1% formic acid-ethanol solution with a volume fraction of 20 times the weight of the mixture, extract at 38°C for 90 minutes, and filter to obtain the filtrate;

[0023] (2) Add sodium secondary alkyl sulfonate and triethanolamine into the filtrate and stir well.

Embodiment 2

[0025] A plant-derived biological herbicide, the raw materials of which are: 20 parts of chamaejasme, 42 parts of podophyllum, 20 parts of baebu, 48 parts of atractylodes rhizome, 2 parts of sodium secondary alkylsulfonate, and 1.5 parts of triethanolamine;

[0026] The preparation method is:

[0027] (1) Mix chamaejasma, podophyllum, herb and atractylodes, add 1% formic acid-ethanol solution with a volume fraction of 20 times the weight of the mixture, extract at 35°C for 120 minutes, and filter to obtain the filtrate;

[0028] (2) Add sodium secondary alkyl sulfonate and triethanolamine into the filtrate and stir well.

Embodiment 3

[0030] A plant-derived biological herbicide, the raw materials of which are: 40 parts of chamaejasme, 35 parts of podophyllum, 30 parts of baebu, 50 parts of atractylodes rhizome, 4 parts of sodium secondary alkylsulfonate, and 1.8 parts of triethanolamine;

[0031] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the field of pesticides, and concretely relates to a botanical biological herbicide adopting a plant extract liquid as a main active component, and a preparation method thereof. The biological herbicide is prepared from, by weight, 20-40 parts of Radix Euphorbiae Ebractealatae, 35-50 parts of Common Dysosma Rhizome, 20-30 parts of Radix Stemonae, 43-50 parts of Atractylodes lancea, 2-4 parts of sodium secondary alkyl sulfonate and 1.5-1.8 parts of triethanolamine. The botanical biological herbicide adopting synergism of raw materials has a good killing effect on various weeds, and has the advantages of fast effectiveness, no untoward effects on crops, no medicine residual, improvement of the quality of crops, increase of the output of the crops, and environmental protection.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a botanical biological herbicide with a plant extract as the main active ingredient and a preparation method thereof. Background technique [0002] Herbicides mainly inhibit, hinder or interfere with various important physiological and biochemical processes of plants, so that weeds cannot grow normally and die. In recent years, a variety of herbicides have been widely used in my country. The use of herbicides has reduced costs for farmers, reduced labor force, and improved productivity. It is a manifestation of the progress of modern agricultural production. However, due to blind abuse, large or excessive use of various herbicides not only affects agricultural production and crop yields, but also has serious negative impacts on the ecological environment, such as water and soil pollution, soil detoxification ability decline, local microclimate damage, etc. . Long-term use ...
