Abstract
A kind of preparation method of agricultural chemicals.The present invention relates to the preparation method that a kind of agricultural chemicals is an insecticidal bactericide, with plant extracts such as chinaberry cellulose solution, nicotine and vegetalitas anaesthetic etc. is primary raw material, allocate the mixture of carbon disulphide and pine tar into, through mixing the broad spectrum activity agricultural insecticide sterilization agent of making a kind of high-efficiency low-toxicity after the stirring, its raw material is easy to get, and production technology is simple.
Description
The present invention relates to a kind of preparation method of agricultural chemicals, belong to AOIN65/00, AOIN65/02, AOIN59/04.
The existing agricultural chemicals that uses both at home and abroad; major part is to be raw material with the organic or inorganic chemical substance; be made through chemical method; as organic phosphor; agricultural chemicals such as organochlorine class; though these agricultural chemicals have Pesticidal and sterilizing effect preferably; but can bring certain influence to the environmental protection and the ecological balance; cause the disorder of the environmental pollution and the ecological balance thereof, and existing certain plants property or the biological agricultural chemicals of producing and using both at home and abroad, though do not cause environmental pollution or ecological balance disorder; but for various reasons; or raw material source difficulty, or complex manufacturing, or contained medicinal ingredient is single; or the like, consequently production and use still are subjected to certain restriction.
The object of the present invention is to provide that a kind of raw material is easy to get, manufacturing process is simple, the preparation method of the broad spectrum activity agricultural insecticide sterilization agent of high-efficiency low-toxicity.
Insectofungicide of the present invention is primary raw material such as chinaberry cellulose solution, 40% nicotine sulphate, vegetalitas anaesthetic etc. with the plant extracts, allocates the mixture of carbon disulphide and pine tar again into, stirs and makes through mixing.
Wherein, the preparation method of chinaberry cellulose solution is: after the root of chinaberry (Melia azedarach/L.) or skin or leaf or fruit chopping or fragmentation, with alcohols preferably the sealing of ethanol or methyl alcohol soak, the usage amount of alcohols is covered soak and is as the criterion just to flood, soak time is 24～48 hours.Soak the filtration of good back and collect filtrate, filter residue is squeezed the juice with crusher, and institute's squeezeding juice mixes with filtrate, and the heating recovery alcohols material is measured concentration and is as the criterion to reach Baume 40～60 degree.
40% nicotine sulphate is directly making after nicotine and the dilute sulfuric acid mixing stirring by known method.Or to be about to water content with simpler method be after about 50% tobacco (bar or leaf) squeezes the juice, filters, concentrates, and adds dilute sulfuric acid and make in concentrate.
The preparation process of mixture of carbon disulphide and pine tar is: the pine tar solution of the carbon disulphide of 60～70Wt% and 40～30Wt% (fusion of heating in advance forms) is put into autoclave, in 300～400 ℃ preferably 350 ℃ rob temperature reaction, reaction time is 1～2 minute, makes to make adhesive carbon disulphide and pine tar mixture.
Vegetalitas anaesthetic is with Chinese prickly ash (ZanthoXYlUm SchinifoliUm S.et/Z. or ZanthoXYlUm bUngeanUm MaXim) seed or leaf, three Ye Liangen or leaf and the tuber of pinellia (Pinellia ternata(ThUnb.) Breit) respectively by making in 50～100 ℃ of boilings 1～5 hour after 1/3rd the amount mixing, amount of water is 4～6 times of mixture to root.
After above-mentioned soup prepares, again by chinaberry cellulose solution 15Wt%, the amount of carbon disulphide and pine tar mixture 30～50Wt%, 40% nicotine sulphate, 50～30Wt%, vegetalitas anaesthetic 5Wt% is mixed, and stirs after 30～60 minutes, promptly makes agricultural broad spectrum insecticide bactericidal agent of the present invention.
During use, convert water sprinkling crop in 1/500～1/1000 ratio and get final product.
Insectofungicide of the present invention, raw material is easy to get, and manufacture craft is simple.Striped rice borer, paddy stem borer, leaf roll snout moth's larva, rice plant skipper, mythimna separata etc. are had killing action, and rice blast, banded sclerotial blight etc. is had certain control efficiency, have the Pesticidal and sterilizing double action, be a kind of agricultural chemicals of broad spectrum activity.Simultaneously, agricultural chemicals of the present invention mainly is made up of the effective medicinal ingredient of plant, and people and animals and other useful biology such as frog, fish, honeybee class, spider, snake class etc. are not all produced poisoning, helps environmental protection and keeps the ecological balance.
Below by embodiment the present invention further is illustrated.
The preparation of embodiment 1 chinaberry cellulose solution
Get 10 kilograms of chinaberry roots, put into a container after cleaning chopping, add 5 kilograms of 75% ethanol, seal, soak after 24 hours, filter to get filtrate, filter residue is squeezed the juice with crusher, filtrate is mixed heating recovery ethanol with squeezeding juice, measure concentration and reach Baume 40～60 degree, promptly get the chinaberry cellulose solution.
The preparation of the mixture of embodiment 2 carbon disulphide and pine tar.
Earlier with 4 kilograms of pine tars in 200 ℃ of dissolving pine tar solution of heating, again pine tar solution and carbon disulphide are put into autoclave for 6 kilograms, in 350 ℃ of reactions 1 minute, the mixture of adhesive carbon disulphide and pine tar.
The narcotic preparation of embodiment 3 vegetalitas
Chinese prickly ash seed, three Ye Liangen, tuber of pinellia root are respectively got 1 kilogram, put into pot, add 12 kilograms in water, add a cover boiling 1 hour in 100 ℃, filter vegetalitas anaesthetic.
The preparation of embodiment 4 agricultural chemicals of the present invention
Get 1.5 kilograms of chinaberry solution, 5 kilograms of 40% nicotine sulphates, 3 kilograms in carbon disulphide and pine tar mixture, 0.5 kilogram in vegetalitas anaesthetic mixes the back and stirred 40 minutes, and just being able to desinsection is main agricultural chemicals.
The preparation of embodiment 5 agricultural chemicals of the present invention
Get 1.5 kilograms of chinaberry cellulose solutions, 3 kilograms of 40% nicotine sulphates, 5 kilograms in the mixture of carbon disulphide and pine tar, 0.5 kilogram in vegetalitas anaesthetic fully mixed 40 minutes, and being cured the disease is main agricultural chemicals.
