Abstract
The invention relates to a pest essential oil pesticide for unprocessed grains stored in a barn. The pest essential oil pesticide is prepared from the following components in percentage by weight: 10-35% of sophora flavescens, 10-50% of chinaberry seeds, 5-35% of radix stemonae, 25-30% of an extraction solvent, 5-20% of a dispersing agent, 3-20% of radix euphorbiae lantu and 10-50% of wintergreen. The invention relates to the pest essential oil pesticide for unprocessed grains stored in the barn and a preparation method of the pest essential oil pesticide. The pest essential oil pesticide is a dark brown essential oil. The invention mainly aims to overcome defects of the traditional pesticide and provide the essential oil pesticide which is high in pesticidal efficiency, little in pollution and capable of sufficiently adapting to a grain bulk ecological system. The pesticidal mechanism is as follows: the nerve center of a pest is palsied, furthermore, the protein of the pest is solidified, pores are blocked, and thus, the pest is choked to death and the pest essential oil pesticide has the fusion killing function for stomach toxicity. The pesticide prepared by the invention has the characteristics of strong toxicity killing capability for unprocessed grain pests such as maize weevil, rhizopertha dominica and tribolium castaneum, wide application range, good preventing and controlling effects, long validity, no easiness for generating pesticide resistance and the like. The pesticide is simple in production process and equipment, free of three wastes in a production process and beneficial to environment protection.
Description
Technical field
The present invention relates to raw grain grain storage pest essential oil insecticide and preparation method thereof in a kind of silo.
Background technology
At present, the storage of raw grain is perplexed by grain storage pest always.Traditional insecticide is often served side effect to the raw grain storage belt, and grain storage pest is produced resistance, conventional pesticides also receives much concern to the pollution of environment and to the harm of people and poultry, and the grain storage fumigant of global applications has destruction to ozone layer, and the World Food Programme (FAO) has determined progressively to stop its production and use.Moreover interact again between each abiological constitution in the grain heap ecosystem, the temperature of whole grain storage environment also has certain impact to grain storage pest, and traditional insecticide is not taken into account the impact of grain storage environment.
Summary of the invention
The technical issues that need to address of the present invention are, overcome the deficiency of conventional pesticides, and the essential oil insecticide that a kind of insecticide efficiency is high, pollute less, can fully adapt to the grain heap ecosystem is provided.
Technical scheme of the present invention is achieved in that raw grain grain storage pest essential oil insecticide in a kind of silo, is become with the percentage by weight array by following component:
Kuh-seng: 10%-35%
Chinaberry: 10%-50%
The tuber of stemona: 5%-35%
Extract solvent: 25%-30%
Dispersant: 5%-20%
The root of langdu: 3%-20%
Wintergreen: 10%-50%
Described extraction solvent is comprised of acetone or ethyl acetate, and described dispersant is starch.
Insecticidal mechanism of the present invention: cause insect nerve center paralysis, and then to the polypide protein coagulating, stop up pore, insect is choked to death, have to melt and kill and stomach poison function.
Range of application of the present invention: when adopting acetone as the extraction solvent, can kill red flour beetle, lesser grain borer, corn weevil, killing rate can reach 85%, can effectively prevent and treat coffee bean weevil, adzuki bean weevil, broad bean weevil, gelechiid, meal moth, the ancient moth of India; When adopting ethyl acetate as the extraction solvent, can kill red flour beetle, lesser grain borer, corn weevil, killing rate can reach 80%, can effectively prevent and treat coffee bean weevil, adzuki bean weevil, broad bean weevil, gelechiid, meal moth, the ancient moth of India.
Technological process of the present invention: raw material metering-extracts active ingredients-concentrated-mixing-finished product-packing.
Color of the present invention: be the dark-brown essential oil.
Advantage of the present invention and beneficial effect are: the insecticide that the present invention makes has the characteristics such as virus killing power is strong, the scope of application is wide, control efficiency is good, the term of validity is long, be difficult for developing immunity to drugs to original grain pest corn weevil, lesser grain borer, red flour beetle etc.This insecticide production technology and equipments is simple, without the three wastes, is conducive to environmental protection in production process.
Lower mask body narration embodiments of the invention:
1, collocation method of the present invention is: with kuh-seng 20%, chinaberry 25%, the tuber of stemona 20%, the root of langdu 15%, wintergreen 25% takes out by weight percentage respectively, mixes, and add the acetone of sufficient dosage to mix, the sample that mixes is carried out the hot reflux that adds of 100 ℃, be cooled to and add dispersant fully to stir after normal temperature to mix, then obtain finished product.
