Embodiment 1

[0026] Drying 30 parts by weight of Speranthum, 20 parts by weight of Scopolamine and 50 parts by weight of Veratella at 60°C-80°C for 15-24h, pulverizing, passing through a 250-mesh sieve to obtain Herbal Speranthum powder, Scopolamine herbal powder and hellebore herbal powder;

[0027] Add the above-obtained herbal medicine powder, scopolamine herbal powder and veratrum herbal medicine powder respectively into the reaction kettle, soak in ethanol with a volume fraction of 80% for 4 hours, then perform ultrasonic extraction, and then separate and obtain the extract of Speranthemus osperatus and the extract of scopolamine and Veratrum extract; the extraction temperature is normal temperature, the extraction time is 250min, the solid-liquid ratio is (1:9) g / ml, and the acoustic power density is 2W / cm 2 , the acoustic frequency is 40 kHz.

[0028] A pesticide composition was obtained by mixing the obtained extracts of Sperancis fragrans, Hyospolamine and Veratrum extracts.

Embodiment 2

[0030] Drying 30 parts by weight of Speranthum, 20 parts by weight of Scopolamine and 50 parts by weight of Veratella at 60°C-80°C for 15-24h, pulverizing, passing through a 250-mesh sieve to obtain Herbal Speranthum powder, Scopolamine herbal powder and hellebore herbal powder;

[0031] Add the above-obtained herbal medicine powder, scopolamine herbal powder and veratrum herbal medicine powder respectively into the reaction kettle, soak in ethanol with a volume fraction of 80% for 4 hours, then perform ultrasonic extraction, and then separate and obtain the extract of Speranthemus osperatus and the extract of scopolamine thing and veratrum extract; the extraction temperature is normal temperature, the extraction time is 250min, the solid-liquid ratio is (1:9) g / ml, and the acoustic power density is 3W / cm 2 , the acoustic frequency is 50 kHz.

Abstract

The invention provides pesticide composition containing veratrum nigrum as well as a preparation method and an application of the pesticide composition and belongs to the technical field of pesticides. The pesticide composition is prepared from components in parts by weight as follows: 50 parts of veratrum nigrum extract, 30 parts of phryma leptostachya extract and 20 parts of Scopolia root extract. According to the pesticide composition, an environment-friendly and pollution-free method is adopted for treating kidney bean pest and disease damage and Chinese herb extract agents are utilized for controlling the kidney bean pest and disease damage during production on the basis of initial source and transmission route of the kidney bean pest and disease damage as well as occurrence characteristics of common pest and disease damage such as red spider, flower thrips, aphid, pieris rapae and the like in kidney bean seed production, so that organic production of kidney bean seeds is realized. With the adoption of the pesticide composition for controlling the kidney bean pest and disease damage, incidence rate of the pest and disease damage of the kidney bean seeds is obviously reduced and can be reduced to be within 10% from 40%.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing veratrum and its preparation method and application. Background technique [0002] As people's requirements for environmental livability and food safety are increasing, the environmental and food pollution problems caused by excessive or improper use of chemical pesticides have gradually attracted people's attention. Broad-spectrum pesticides with high efficiency, low toxicity, low residue, and environmental compatibility that meet the concepts of environmental protection, health, and sustainable development have become the direction of pesticide development and research today. The insecticidal or bactericidal components in the currently used pesticides are all chemical compounds with certain toxicity, which have certain toxic and side effects and environmental residues on humans, animals and the environment, and cannot be used in...
