Abstract
The invention relates to a biological pesticide and a preparation method thereof. A raw material of the biological pesticide is an extract from mulberry leaf water, namely total alkaloids from folium mori. The method for preparing the biological pesticide comprises the steps of: cutting mulberry leaves into thin bar shapes with the width of about 2mm, adding water into the mulberry leaves in a solid-liquid mass ratio of 1: 10, performing ultrasonic treatment on the mixture for 1 hour, then boiling the mixture until the content of the mulberry leaves is about 1g/ml, and filtering the obtained solution to obtain a finished product. The invention provides a biological pesticide with no toxicity, no harm, simple preparation technology, and easy popularization and application, and the preparation method thereof.
Description
Technical field
The present invention relates to novel agrochemical and preparation method thereof.
Background technology
China is as large agricultural country, the production of agricultural product, outlet occupies important proportion in national economy, in order to make crops energy smooth growth, prevent insect pest, in the process of growth of crops, all can impose agricultural chemicals and come deinsectization, expelling parasite, still in agricultural production, still use the agricultural chemicals of hypertoxic high residue so far, agricultural residual the exceeding standard of vegetables, fruit, tealeaves and cereal crops causes that food poisoning takes place repeatedly.After the China's WTO entry, the standard of residue of pesticide has all improved to the agricultural product of China in states such as European Union, Japan, has limited the outlet of China's Agricultural widely.Biopesticide occurs alleviating the toxic problem of agricultural chemicals greatly, but there is following problem in present biopesticide, preparation difficulty, unstable product quality.The active ingredient of many biopesticides is living microorganism, because its product formulation specification requirement height, the formulation and the production technology thereof that add China's biologic product fall behind, content of effective all can't reach the commercialization requirement between the physical and chemical index of product, stability and different batches, causes the living microorganism pesticidal preparations to change into a bottleneck that develops into China's biopesticide.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of nontoxic, preparation technology is simple, is easy to promote biopesticide of using and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of biopesticide, its raw material are mulberry leaf water extract mulberry leaf total alkaloid.
The preparation method of biopesticide is cut into the elongated strip of wide about 2mm with mulberry leaf, adds water at 1: 10 with the solid-liquid mass ratio, and ultrasonic processing was boiled to the about 1g/ml of mulberry leaf content after 1 hour, and filtration gets product.
The present invention is made up of mulberry leaf water extract mulberry leaf total alkaloid.The present invention is the alkaloidal single pharmaceutical formulation of the biologically active that extracts from the natural plants mulberry leaf, it make and use in not with an organic solvent, and do not need reprocessing just can directly use, be nontoxic to people, animal, fowl etc., the natural plants source biological pesticide of efficient, the high security of environmentally safe.Products material abundance of the present invention, cheap, insecticidal action is good, and the preparation method is simple, does not produce " three wastes " pollutant in suitability for industrialized production, is beneficial to and applies.Product of the present invention acts on the farm product, and product has noresidue, non-carcinogenesis and cumulative toxicity, can guarantee the organic property and the safety of food.Product of the present invention can replace the use of existing cytotoxic chemical agricultural chemicals on agricultural product, make the peasant produce pollution-free food and green organic product, guarantee that product of the present invention is in vegetables, the production of tealeaves main product ground, pesticide material is with low cost, production method is simple, added value height, suitability for industrialized production do not produce " three wastes " pollutant, can realize zero-emission.
Case effect of the present invention is as follows: product of the present invention acts on the brassicaceous vegetable cabbage caterpillar, uses once, and killing rate can reach 80% in 24 hours.Act on tealeaves smaller green leaf hopper, locust, 24 hours killing rates can reach 80%, 48 hour killing rate and reach more than 90%.
Embodiment
Preparation method of the present invention at first gets the mulberry leaf raw material, and mulberry leaf are cut into the elongated strip of wide about 2mm, adds water at 1: 10 with the solid-liquid mass ratio, and ultrasonic processing was boiled to the about 1g/ml of mulberry leaf content after 1 hour, and filtration gets product.
Claims (2)
1. a biopesticide is characterized in that raw material is a mulberry leaf water extract mulberry leaf total alkaloid.
2. the preparation method of biopesticide according to claim 1 is characterized in that mulberry leaf are cut into the elongated strip of wide about 2mm adding water at 1: 10 with the solid-liquid mass ratio, and ultrasonic processing was boiled to the about 1g/ml of mulberry leaf content after 1 hour, and filtration gets product.
