[0026] 1 Preparation of matrine plant extract

[0027] The matrine plant extract is the water extract obtained by mixing 2 to 4 parts of Sophora flavescens, 1 to 2 parts of neem, 1 to 2 parts of Cortex Phellodendri and 1 to 2 parts of castor according to the following parts by weight. The plant extract containing berberine is equivalent to 1g of crude drug. The specific extraction process is as follows: Weigh Sophora flavescens, neem, Phellodendron and castor according to parts by weight, crush them, soak in water for 12-24 hours, the amount of water added is based on the amount of the drug, and stir 2-3 times during soaking , and then heated to 100°C, kept in a slightly boiling state for 1 hour, squeezed and filtered, and the filtrate was centrifuged or left to settle. Then, soak the filtered medicinal dregs in water for 3 to 4 hours, boil for 1 hour and then filter, mix the two filtered liquids evenly, and concentrate the filtrate in a low-temperature vacuum until each mill...

Abstract

The invention relates to a matrine chlorpyrifos aqua which is characterized in that chlorpyrifos and matrine plant extract are composed into the aqua, wherein, the content of the chlorpyrifos is 1mg / L to 2mg / L and the content of the matrine plant extract is 2mg / L to 5mg / L. The matrine chlorpyrifos aqua, by composing two kinds of pesticides with different mechanisms of action, not only can be favorable to solving the drug resistance of pests but also can improve the property of each drug, i.e. the dosage of the chlorpyrifos is greatly reduced, while the toxicity of the chlorpyrifos against thepests and the control of the matrine plant extract over the pests are improved; simultaneously, the aqua takes water as basic material, thus solving the problems of flammability and hazard caused by organic solvents and avoiding poisoning people and livestock and polluting environment.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, in particular to a matrine chlorpyrifos aqueous solution. Background technique [0002] Matrine is a chemical component of Chinese herbal medicine leguminous plant Sophora flavescens, which belongs to the class of quinazinidines in alkaloids, and its molecular formula is C 15 h 24 N 2 O, the structure is as follows: [0003] [0004] At present, it has been proved that matrine has an insecticidal effect, and the mechanism of action is to paralyze the nerve center of the pest, and then solidify the protein of the insect body, block the stomata of the insect body, and cause the pest to suffocate to death. There have been many reports of matrine controlling agricultural and sanitary pests, and it has poisonous effect on many kinds of pests, such as cabbage caterpillar, elm blue leaf beetle aphid, radish aphid, diamondback moth, wheat aphid, etc. At the same time, it was proved t...
