Abstract

The invention relates to a plant source pesticide and a preparation method thereof. The pesticide is composed of the following raw materials: selinum japenious seed, officinal magnolia bark, Chinese ephedra, peganum harmala, artemisia scoparia, pokeberry root, mirabilis jalapa, pyrethrin, furocoumarin, ethylicin, rotenone, ricin, sodium alginate and sodium cyclamate. The preparation method comprises the following steps: mixing part of the raw materials and water to form a solution; then performing mixed stirring on a water extraction solution of the part of the raw materials, and adding the remaining raw materials to prepare the plant source pesticide. The prepared plant source pesticide acts on pests, weeds and bacteria, various virus ways and mechanisms are adopted, the pests are not directly killed in general, the growth of a pest population is inhibited, the selectivity is high, and natural enemies of the pests are protected favorably; due to substances which naturally exist, the safety is high, residues are not easily generated after the plant source pesticide is applied to crops, and the phenomenon of biological concentration is not easily caused.

Description

A kind of botanical pesticide and preparation method thereof

Technical field

The present invention relates to technical field of pesticide, be specifically related to a kind of botanical pesticide and preparation method thereof.

Background technology

Tradition agricultural chemicals majority is chemicals, and drug residue is large, polluted-water and ecotope, and as what is the need for plant resource as farm chemical ingredients, reducing pollution is the technical issues that need to address.Therefore, need to occur that a kind of proportioning is simple, easy to use, be major ingredient with botanical material, prepare botanical pesticide, the preparation method of a kind of botanical pesticide that pollution level is little.

Summary of the invention

The object of the present invention is to provide a kind of botanical pesticide and preparation method thereof.

The technical solution used in the present invention is, a kind of botanical pesticide, and it is made up of following steps:

Get frutus cnidii 30-40 part, bark of official magnolia 20-22 part, Chinese ephedra 12-14 part, harmel 10-12 part, Artemisia scoparia 14-16 part, Phytolacca acinosa 15-17 part, [common 15-17 part, pyrethrin 1-2 part, furocoumarin 1-3 part, S-Ethyl ethylthio sulfonate 2-4 part, rotenone 1-2 part, ricin (WA) 1-3 part, sodium alginate 3-5 part, sodium cyclohexylsulfamate 0.3-0.6 part;

The allotment that pyrethrin, furocoumarin, S-Ethyl ethylthio sulfonate, rotenone, ricin (WA) added water is the solution A of 10% in mass percent concentration, for subsequent use; Flooding method is adopted to extract leaching liquor B frutus cnidii, thick part, Chinese ephedra, harmel, Artemisia scoparia, Phytolacca acinosa, [common; Solution A is mixed with leaching liquor B, adds sodium alginate and sodium cyclohexylsulfamate stirs and obtains botanical pesticide.

It is varied that the made botanical pesticide of the present invention acts on insect, weeds, bacterium, viral mode and mechanism, generally directly do not kill pest, but suppress pest population growth, and selectivity is high, is conducive to protecting pest natural enemy; Owing to being the material that nature exists, safety is good, is applied to crop and not easily produces residual, not easily cause biological concentration phenomenon; Add sodium cyclohexylsulfamate in medicine and improve its sweet taste, add palatability of drugs, can more large batch ofly kill off the insect pests, sodium alginate is used for can strengthening viscosity and the tack to crop in medicine, slows down the loss of drug ingedient; Again because the swelling of alginic acid microgel particle has pH susceptibility, particulate (pH1.5KCl-HCl) in distilled water or acid medium is unchanged, and swelling rapidly in the phosphate buffer of pH8.0, so this medicine can have more drug effect on the crop pest management of salinized soil.
