preparation example Construction

[0030] The preparation method of above-mentioned compound botanical pesticide comprises the following steps:

[0031] ⑵Take sophora flavescens, veratrum, centipede, neem, goat flower and mugwort leaves without mildew or deterioration, clean them and set aside;

[0032] (2) Add the components of step (1) into 8 times the weight of cold water and decoct at a temperature of 120°C for 2 hours;

[0033] (3) Filter out the medicinal residues, and concentrate each medicinal solution at low temperature separately to form a liquid extract;

[0034] (4) Mix each liquid extract in proportion, and form mother liquor after adding water;

[0035] (5) The mother liquor of step (4) is further processed through a colloid mill and a homogenizer, and then left to stand in a storage tank for 72 hours;

[0036] ⑹ Take the supernatant after standing still, add additives and synergists in proportion, and then stir evenly in the traditional Chinese medicine emulsification pot to make the finished p...

Abstract

The invention relates to a composite plant source pesticide, which is characterized by including a mother liquid and an additive. The mother liquor comprises the following raw materials by weight: 35% of a Sophora flavescens extract, 35% of a resveratrol extract, 10% of a radix stemonae extract, 10% of a Melia azedarach extract, 5% of a Chinese azalea flower extract and 5% of a folium artemisiae argyi extract. A preparation method provided by the invention comprises the steps of: weighing the Sophora flavescens, resveratrol, radix stemonae, tobacco, Melia azedarach and folium artemisiae argyi according to the proportion; conducting screening, boiling extraction and purification to prepare an extract containing active ingredients of each component; and then mixing the mother liquor and the additive to obtain the product. Through various tests, the product has no adverse excitant smell, no drug residue, no damage to human, livestock, agricultural products, air and soil, has insecticidal and antimicrobial effects, and is suitable for usage in field, greenhouse, nursery, golf course, tea garden and forestry greening.

Description

technical field [0001] The invention belongs to the technical field of plant pesticides, in particular to a compound plant-derived pesticide and a preparation method thereof. Background technique [0002] Pesticides are mainly used to control agricultural pests and urban sanitation pests. They have a long history of use, a large amount of use, and many varieties. Today, with the rapid development of agriculture, the use of various pesticides has greatly increased agricultural output. Classification of mode of action can be divided into stomach poisons, contact killers, fumigants and systemic insecticides, which can be classified into nerve agents, respiratory poisons, physical poisons and specific insecticides according to toxicological effects, but almost all Pesticides can seriously alter the ecosystem, most of which are harmful to humans and animals. [0003] With the progress of society, food safety issues are increasingly being paid attention to by people, and the prob...
