Embodiment 1

[0030] Manufacture of oxymatrine water agent, from flavescens, bitter bran, tobacco, deer vine, tripterygium wilfordii, maple willow, hops, lawn grass, mountain pepper, after cleaning, crushing, extraction, concentration, alcohol precipitation, back distillation, It is made by mixing, and the compatibility of its Sophora flavescens, Kudi, tobacco, deer vine, tripterygium vine, maple hop and pepper is: 20% of sophora flavescens, 20% of bitter plants, 10% of tobacco, 5% of deer vine %, tripterygium 5%, maple willow 20%, hops 6%, lawn 4%, mountain pepper 10%.

[0031] Its process procedure is:

[0032] 1. According to the above compatibility, take Sophora flavescens, bitter plant, tobacco, deer vine, tripterygium wilfordii, maple willow, hops, lawn grass, and Zanthoxylum bungeanum, respectively, wash with water, dry and pulverize, and sieve with a 20-80 mesh sieve;

[0033] 2. Extract with imitation respectively, reduce with water, then concentrate, intoxicate (using ethyl alcoh...

Embodiment 2

[0035] The third raw material compatibility for making oxymatrine water agent is: flavescens 6%, bitter bran 30%, tobacco 10%, deer vine 6%, tripterygium 20%, maple willow 4%, hops 10%, law Grass 6%, mountain pepper 10%. The pesticide has special effects on pests. The production technology of embodiment two is identical with embodiment one.

Abstract

The invention discloses an oxymatrine aqueous solution plant bactericide and a preparation method thereof and aims to provide a plant bactericide which takes Chinese herbal medicines as raw materials, has no harm on people and animals, is low in toxin and low in cost, is super-efficient and has high content of oxymatrine, and a preparation method of the plant bactericide. The plant bactericide belongs to a plant insecticide, contains super high content, about 2.4%, of oxymatrine, takes contact killing as a main manner and suffocation as an auxiliary manner and has good effects on killing aphids, whiteflies, red spiders and the like. The oxymatrine aqueous solution plant bactericide has the characteristics of high decomposition speed, high efficiency, low toxin, no residues, no pollution and the like, and is a safe type domestic or flower-cultivation insecticide.

Description

technical field [0001] The invention belongs to the field of biopesticides, and more specifically relates to a preparation method of a plant extract insecticide mainly composed of a matrine plant extract and an aqueous solution. Background technique [0002] my country is a typical agricultural country. The three rural issues have always been one of the important policies of our country. For a long time, due to the extensive use of chemical pesticides, the vast number of rural agricultural product production bases have suffered serious three pests, and the resistance of diseases and insect pests has continued to increase, burying hidden dangers to the safety of agricultural products. In addition, the pollution of pesticide residues to the environment has become increasingly prominent. The three pests problem not only restricts the development of agriculture, but also seriously endangers human life and health. The harm it causes is immeasurable. The government has also tak...
