Abstract
The invention discloses a plant powder pesticide and a method for preparing the same. The plant powder pesticide comprises the following plant raw materials in weight portion: 200 to 300 weight portions of macleaya cordata, 300 to 400 weight portions of euphorbia humifusa, 200 to 300 weight portions of polygonum spicy, 50 to 150 weight portions of licorice powder, 300 to 400 weight portions of anisodus mairei, 150 to 250 weight portions of cortex pseudolaricis, 200 to 300 weight portions of cortex moutan, 150 to 250 weight portions of agrimony, and 150 to 250 weight portions of lycoris radiata. The method is relatively simple to operate, is carried out at normal temperature and pressure, and consumes low energy; and various plant raw materials can be combined together to be extracted mostproperly at the normal temperature, and mutual influences of the components are smaller. The plant powder pesticide has better killing effect on rice leaf insects, cabbage caterpillars, and aphids. The antifeedant rates to pests are more than 96 percent, and the mortality rate is more than 80 percent. The plant powder pesticide adopts a compound preparation of various plant components so that pests are not easy to generate drug resistance generally.
Description
Technical field
The present invention relates to a kind of agricultural chemicals, specifically a kind of by the composite plant powder pesticide that forms of various plants.The invention still further relates to the preparation method of this plant powder pesticide.
Background technology
Because big, the difficult degraded of the toxicity of some chemical synthetic pesticide own, residual height; In producing and using; Caused the catastrophic destruction of ecotope, and direct threats human fertility system, nervous system, children's brain is grown constitute injury; Cause body immunity low, cancer morbidity rises.Simultaneously, because the long-term chemical synthetic pesticide that uses makes insect produce pesticide resistance, brought difficulty to chemical control.Be that conservation of nature environment and human body are healthy, seek efficient, low toxicity, pollution-free, not residual " green " agricultural chemicals, become the inexorable trend of the future of agriculture development and an important assurance of agricultural sustainable development.
Plant pesticide derives from natural plants, itself is exactly one of part of ecotope, is invested in natural world, and is very little to environment and whole ecological systematic influence, even not influence.
But; Because the contained composition of plant corpus is complicated; Except the effective ingredient that contains desinsection, also contain other organic matter, make the shelf-life of plant pesticide short, character is unstable; Particularly liquid plant pesticide deposition occurs after placing a period of time easily, and use in the drug effect and the land for growing field crops that have greatly influenced plant pesticide.
Summary of the invention
The purpose of this invention is to provide a kind of Pesticide with Chinese medicinal material pulvis stable in properties, long shelf-life by pure plant preparation.
Providing a kind of method of operating comparatively simple, help this plant powder pesticide preparation method of drug effect performance again, then is another goal of the invention of the present invention.
Vegetable insecticide pulvis of the present invention is the plant material by following portions by weight,
Macleaya cordata 200-300 wolf's milk 300-400
Polygonum flaccidum 200-300 unpeeled RADIX GLYCYRRHIZAE 50-150
Chinese atropanthe root 300-400 corter pseudolaricis 150-250
Root bark of tree peony 200-300 hairyvein agrimony 150-250,
Short-tube lycoris 150-250
Wherein, the root bark of tree peony, short-tube lycoris, Chinese atropanthe root, corter pseudolaricis, unpeeled RADIX GLYCYRRHIZAE roll into meal altogether in the above-mentioned plant material, and 70% ethanol of doubly measuring with 4.5-5.5 carries out diacolation, and percolate reclaims ethanol.The water of again macleaya cordata, wolf's milk, hairyvein agrimony, polygonum flaccidum doubly being measured with 6-8,80-90 ℃ of digestion 1-1.5h, cooling.Then, with the aqueous extract of plant materials such as the percolate of plant materials such as the above-mentioned root bark of tree peony and above-mentioned macleaya cordata mix, concentrate, atomized drying, add 0.2% composite the forming of nonionic surface active agent again.
The present invention has quoted drug manufacture technology percolation, can extract active ingredient as much as possible, and remove invalid components, has guaranteed stability of the present invention and shelf-life.This method operation is simple relatively, is to carry out at normal temperatures and pressures, and it is low to consume energy; And the most suitable various plants raw material combines extraction under the normal temperature, and the composition between component influences each other less.
Add nonionic surface active agent among the present invention, strengthened water-solublely, improved tack and the permeability of land for growing field crops when using.Use is the result show: rice leaf roll worm, cabbage caterpillar, aphid are all had lethal effect preferably.All more than 96%, lethality is more than 80% to the food refusal rate of insect.
Because the compound formulation that the present invention has adopted various plants to form, insect generally is not easy to develop immunity to drugs.
Have synergy between each component, and when prescription, pay attention to having added plant sterilization or antibacterial kind, so the present invention has the effect of control crop pests and disease.
Embodiment
1. the root bark of tree peony, short-tube lycoris, Chinese atropanthe root, corter pseudolaricis, unpeeled RADIX GLYCYRRHIZAE roll into meal altogether, and be earlier moistening with 70% ethanol, flooded 12 hours, raw material is fully expanded after, the diacolation equipment of packing into was with 20ml/ minute speed diacolation.With percolate recovery section ethanol, store subsequent use.
2. macleaya cordata, wolf's milk, hairyvein agrimony, polygonum flaccidum break into meal, after water fully soaks, are heated to 85-90 ℃, extract 1-1.5 hour, filter, and filter residue is added water logging again boiled 1 hour, and merging extracted twice liquid is concentrated into and contains raw material 30-35%.
3. above-mentioned ethanol extract and water extraction concentrate are carried out atomized drying, and add 0.2% nonionic surface active agent, fully the mixing packing is finished product.
