Embodiment Construction

[0028] 1 Preparation of berberine plant extract

[0029] Weigh 40-50 parts of three needles, 1-2 parts of Phellodendron cortex, 45-50 parts of perilla, and 2-3 parts of castor-oil according to parts by weight. After crushing, soak in water for 12-24 hours. The amount of water added should be over The medicinal material shall prevail. Stir 2-3 times during the soaking period, then heat to 100°C, keep in a slightly boiling state for 1 hour, press and filter, centrifuge the filtrate or place it for precipitation, and soak the filtered medicinal dregs in water for 3-4 hours. After boiling for 1 hour, filter, mix the two filtrates evenly, concentrate the filtrate in vacuum at low temperature until each milliliter of medicinal liquid contains 1 g of crude drug, and obtain the berberine plant extract.

Abstract

The invention relates to a berberine imidacloprid aqua which is characterized in that imidacloprid and berberine plant extract are composed into the aqua, wherein, the content of the imidacloprid is 1mg / L to 2mg / L and the content of the berberine plant extract is 15mg / L to 20mg / L. The berberine imidacloprid aqua, by composing two types 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 imidacloprid is greatly reduced, while the toxicity of the imidacloprid against the pests and the control of the berberine 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 berberine imidacloprid aqueous solution. Background technique [0002] Berberine is the active ingredient in the three needles of medicinal plants and Cortex Phellodendri. It belongs to the benzyl-isoquinoline class of alkaloids, and its chemical formula is: 5,6-Dihydro-9,10-dimethoxybenzo[ g]-1,3-benzodioxzolo[5,6-a]quinolizinium, the structure is as follows: [0003] [0004] Berberine is an insecticidal active ingredient, which has photoactivated toxicity to pests, that is, the lethality to pests can be increased several times or even thousands of times under light, and can be used to make high-quality raw materials for plant-derived biopesticides. However, due to the poor single-dose quick-acting performance of botanical biopesticides in production, there are defects such as slow efficacy on pests, poor efficacy in the field, many spraying times, and low di...
