Abstract
The invention discloses a botanical pesticide prepared by combined extraction of Chinese herbal medicines. Active ingredients of the botanical pesticide are obtained by combined extraction of the following Chinese herbal medicines in parts by weight: 10-20 parts of tobacco leaves, 20-30 parts of radix sophorae flavescentis, 30-50 parts of celastrus angulatus, 50-60 parts of stellera chamaejasme, 10-30 parts of cuckoo-buds and 10-30 parts of seriphidium finitum. A preparation method of the botanical pesticide comprises the following steps: air-drying and grinding the Chinese herbal medicines, soaking in ethanol or methanol for 2-8 hours, cyclically extracting for 2-8 times for 40-60 minutes each time, removing dregs, concentrating extracting liquid at 65-80 DEG C, adding a proper amount of pesticide additives into concentrated liquid, and uniformly mixing. The botanical pesticide has the characteristics of stable preparation, remarkable pesticidal effect, relative safety to people and livestock, low harm to natural enemies of pests, capability of preventing the pests from generating antibodies, low toxicity and low residue content.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Chinese herbal medicine and merge the plant insecticide extracting.
Background technology
The pesticidal preparations that it is active ingredient that botanical pesticide refers to for the plant of prevention and elimination of disease and pests and the extract of plant corpus.When it has pesticide-germicide effect, also there is certain fertilizer efficiency function, without residual hazard and poisoning, pollution-free, classified as by State Development Planning Commission and the Department of Science and Technology industry that 21 century first develops, be the desirable environment friendly agricultural of generally acknowledging.
The plant insecticide of prior art, is all formulated by one or more Chinese herbal medicine extracts and auxiliary agent, and its shortcoming often effective component is single, and broad spectrum activity is poor, or compatibility is unreasonable, a little less than lethality, takes effect slow, and the lasting period is short.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, provide a kind of Chinese herbal medicine to merge the plant insecticide extracting, it has preparation stabilization, and lethality is strong, and broad spectrum activity is good, to person poultry safety, meets the demand for development of green agriculture.
Technical scheme of the present invention is: a kind of Chinese herbal medicine merges the plant insecticide extracting, and its active ingredient merges extraction by the Chinese herbal medicine of following weight ratio and forms: 10～20 parts, tobacco leaf, 20～30 parts of kuh-sengs, 30～50 parts of Celastrus angulatus, 50～60 parts of the roots of langdu, 10～30 parts of Herba Ranunculi Japonicis, 10～30 parts of Flos Artemisiae finitaes.
Further, active ingredient of the present invention is extracted and is formed by the Chinese herbal medicine merging of following weight ratio: 12～18 parts, tobacco leaf, 22～28 parts of kuh-sengs, 35～45 parts of Celastrus angulatus, 52～58 parts of the roots of langdu, 15～25 parts of Herba Ranunculi Japonicis, 15～25 parts of Flos Artemisiae finitaes.
Further, the preparation method that Chinese herbal medicine of the present invention merges the plant insecticide extracting is: by each taste Chinese herbal medicine dried and crushed, in ethanol or methyl alcohol, soak 2～8 hours, circulate and extract 2～8 times, each extraction 40～60 minutes, removes the dregs of a decoction, and extract is concentrated at the temperature of 65～80 ℃, concentrate adds appropriate insecticides adjuvant, and the liquid preparation making that stirs is exactly that Chinese herbal medicine of the present invention merges the plant insecticide extracting.
Further, the percentage by weight of described insecticides adjuvant in liquid preparation is 1～15%.
Further, described insecticides adjuvant comprises stabilizing agent, bleeding agent and light stability agent, and stabilizing agent comprises one or more in formic acid, citric acid, DBSA, fumaric acid and p-methyl benzenesulfonic acid; Bleeding agent comprises one or more in fatty alcohol-polyoxyethylene ether, polyoxyethylene nonylphenol ether and Tween 80; Light stability agent comprises one or more in p-aminobenzoic acid ester, salicylate and benzophenone.
Advantage of the present invention is:
Chinese herbal medicine compatibility and ratio that Chinese herbal medicine of the present invention merges the plant insecticide extracting are the results obtaining through a large amount of scientific experiments, and its compatibility is scientific and reasonable, has broad spectrum activity good, lethality is strong, instant effect, efficiency time is long, and the advantage such as can not develop immunity to drugs.
Chinese herbal medicine of the present invention merges the plant insecticide extracting and degrades at natural world, agricultural chemicals derives from nature, do not pollute the environment and agricultural product, in environment and human body, can not form accumulation toxicity, comparatively safe to people and livestock, little to pest natural enemy injury, and insect is difficult to produce antibody to it, there is the feature of low toxicity, low-residual, the production of nuisanceless green vegetables, grain, fruit is had to positive meaning.
In preparation, can also add stabilizing agent, bleeding agent and light stability agent, increase stability and the efficiency time of insecticide.
