Problems solved by technology

[0002] There are many types of existing pesticides, including chemical pesticides and botanical pesticides. Although chemical pesticides have good insecticidal properties, they are easy to form pesticide residues, and plants are prone to develop resistance
Plant-based pesticides are relatively less toxic. For example, pesticides prepared from tripterygium, tobacco, pyrethrum, and fish teng have certain insecticidal effects, but most of them only have insecticidal effects, and their functions are single, and some of them are distributed in plants. Small, small output, difficult to obtain raw materials

Embodiment 1

[0031] The fresh or dried whole plant of Artemisia annua is used as the main raw material, and it is prepared according to the following method:

[0032] Soak the whole herb of Artemisia annua fresh or dried in water for 4 hours, beat it, repeatedly squeeze the juice 2 to 4 times, filter and let it stand, use activated carbon (or other methods) to decolorize, and concentrate part of the filtrate to obtain Artemisia annua extract (or the filtrate is concentrated and dried to obtain Artemisia annua extract powder); use 68% Artemisia annua extract (or Artemisia annua extract powder) and spreader soap (or other similar substances) 31.6%, preservative potassium sorbate ( or other preservatives) 0.4% mixed to obtain the pesticide of the present invention.

Embodiment 2

[0034] The fresh or dried whole plant of Artemisia annua is used as the main raw material, and it is prepared according to the following method:

[0035] ) Add the fresh or dried whole herb of Artemisia annua to an acidic solution with sulfuric acid and water to adjust pH=2 to 7, soak for 5 hours, beat the pulp, squeeze the juice repeatedly for 3 to 4 times, filter, let stand, and concentrate the filtrate to obtain the Artemisia annua extract Liquid (or made into Artemisia annua extract powder), with 80% Artemisia annua extract (or Artemisia annua extract powder) and spreading agent soap (or other similar substances) 19.6%, preservative potassium sorbate (or other preservatives ) 0.4% mixed to prepare the pesticide of the present invention.

Embodiment 3

Abstract

The invention is a non-toxic and pollution-free pesticide and a preparation method thereof. It is characterized in that the pesticide is prepared from Artemisia annua plants as main raw materials. The non-toxic and pollution-free pesticide contains 68-98% of Artemisia annua plant extract, 1.6-31.6% of spreading agent and the balance of preservative. The preparation method is mainly to soak the fresh or dry whole herb of Artemisia annua, beat, squeeze the juice, filter and let it stand, and concentrate to obtain the Artemisia annua extract or the Artemisia annua extract powder. The invention prepares the plant Artemisia annua as a pesticide, and proposes a new application of the plant Artemisia annua, which is used for broad-spectrum insecticide and fungicide, and is used as a regulator of plant growth. Compared with the prior art, the pesticide of the present invention has the remarkable features of being pollution-free, non-toxic, highly effective in killing insects, having a wide insecticidal spectrum and good effect, and the nitrogen-containing element of the plant extract of Artemisia annua plant is easy to absorb, and the plants grow well after spraying .

Description

technical field [0001] The invention relates to a non-toxic and pollution-free pesticide prepared from plants and a preparation method of the pesticide. Background technique [0002] There are many types of existing pesticides, including chemical pesticides and botanical pesticides. Although chemical pesticides have good insecticidal properties, they are easy to form pesticide residues, and plants are prone to develop resistance. Plant-based pesticides are relatively less toxic. For example, pesticides prepared from tripterygium, tobacco, pyrethrum, and fish teng have certain insecticidal effects, but most of them only have insecticidal effects, and their functions are single, and some of them are distributed in plants. Small, small output, raw materials are not easy to get. Contents of the invention [0003] The purpose of the present invention is to provide a kind of insecticidal insecticidal effect, wide insecticidal spectrum, non-toxic and pollution-free pesticide.
