Abstract
The invention discloses a method for preparing a botanical insecticide containing artemisia. The method comprises the following steps: with an extract of artemisia as a main raw material, dissolving into mixed filtrate of tomato leaves, balsam pear leaves and pumpkin leaves; adding an emulsifier, plant ashes, a synergist and water; and stirring evenly, so as to obtain the botanical insecticide containing artemisia. The botanical insecticide comprises the following components in parts by weight: 80-100 parts of the artemisia extract, 40-60 parts of the mixed filtrate of tomato leaves, balsam pear leaves and pumpkin leaves, 20-30 parts of the emulsifier, 10-30 parts of the plant ashes, 1-20 parts of the synergist and 20-50 parts of water. The botanical insecticide containing artemisia prepared by the method adopts plants as the main raw material, so that the botanical insecticide is nontoxic, is free of pollution, and has significant pesticide effects on insects of vegetables; and the drug resistance is not easily generated.
Description
Technical field:
The invention belongs to technical field of pesticide, particularly a kind of preparation method of the plant insecticide containing high wormwood artemisia.
Background technology:
China is Vegetable produce and consumption big country, quality and yield and our life of vegetables are closely bound up, the damage by disease and insect of vegetables not only can affect the quality and yield of vegetables, and more can affect our healthy for the residual of the used chemical pesticide that destroys plant diseases and insect pests.The particularly selection mistake of medicament, working concentration is excessive or service time is improper, causes most medicament to remain in soil environment, causes soil compaction, water and soil loss etc., affect recycling of soil, have a strong impact on the sustainable development of environment and economy.
Efficiently, the parent that economic, safe biopesticide is more and more subject to people looks at, and the kind of current biological insecticides is a lot, has Imidacloprid, pymetrozine, pyrethrin, matrine, Biphenthrin, Avermectin micro emulsion oil, permethrin milk oil etc.In addition, plant also becomes the favorable substitutes of chemical pesticide as the new type bactericide of primary raw material.
High wormwood artemisia has another name called smelly wormwood artemisia, sweet wormwood, belongs to composite family, in being often grown on hillside shrub, through being often used as Chinese herbal medicine, has effect of clearing away summerheat and cool blood reducing the asthenic fever, has very strong antibacterial, antibacterial and antiviral effect.Therefore the extract of high wormwood artemisia is killed as the insect of bactericide to vegetables and have significant effect.
Summary of the invention:
The object of this invention is to provide a kind of preparation method of the plant insecticide containing high wormwood artemisia, adopt the extract of high wormwood artemisia as primary raw material, the plant insecticide that the mixing filtrate of tomato balsam pear and cushaw leaf is prepared as auxiliary material, this insecticide nontoxic residue-free, easy decomposition, there is significant drug effect to insect, and not easily produce drug resistance.
Object of the present invention is achieved through the following technical solutions:
Containing a preparation method for the plant insecticide of high wormwood artemisia, comprise the following steps:
