Abstract
The present invention belongs to celastrus angulatus insecticidal preparation. It is made up by using the extract of insecticidal plant celastrus angulatus, emulsifying agent, cryoprotectant and water through a certain preparation process. Said invention possesses two types of celastrus angulatus concentrated emulsion and celastrus angulatus micro-emulsion, their insecticidal effect is superior to or equal to that of celastrus angulatus emulsion, but they contain no aromatic solvents of tribenzene, etc., so that they are safe in use, storage and transportation for human, animal and environment.
Description
The invention belongs to the Celastrus angulatus insecticidal agent, particularly the agent of Celastrus angulatus water-base pesticide.
The application for a patent for invention of the national inventing patent of Wu Wenjun etc. " Celastrus angulatus emulsified oil as plant's pesticide and manufacture method thereof " (patent No. ZL 92113104.6) and Wang Maotian " contains insecticide of dihydrolagarane polyalcohol ester composition and preparation method thereof ", and (number of patent application 93101996.6) all addressed with pesticide plant Celastrus angulatus (Celastrus angulatus) root skin to be raw material, to be processed into the insecticidal preparation and the manufacture method thereof of missible oil through organic solvent extraction.But missible oil is not an advanced person's formulation, and its reason is that missible oil is solvent with aromatic hydrocarbons such as triphens mostly, and this is still to the waste of industrial chemicals, and increases the weight of the pollution to environment, in addition, because its combustibility, has increased yet and has stored and the danger of transportation.Celastrus angulatus extract itself is low to the person poultry toxicity, and is safer to environment, be processed into missible oil after, dimethylbenzene, toluene or benzene equal size account for 60～80%, an enterprise that produces 300 tons of Celastrus angulatus missible oil per year will have 180～240 ton of three benzene solvent to be sprayed in the environment and go every year, aggravate environmental pollution.
Purpose of the present invention just provides aromatic solvents such as not containing triphen, nonflammable kinds of celastrus angulatus water base insecticidal preparation, so that safety storing and safer to environment.
Two kinds of kinds of celastrus angulatus water base insecticidal preparation of the present invention are in that polynary ester is to add emulsifiable concentrate and the microemulsion that emulsifier; These two kinds of shared mass percents of each component of pesticide of antifreeze and water make in the Celastrus angulatus extract of active ingredient with dihydroagarofuran. are as follows: Celastrus angulatus emulsifiable concentrate: root bark of celastrus angulatus extract 10～15% emulsifying agents 8～12% antifreezes 10% water 63～72% Celastrus angulatus microemulsions that contain dihydroagarofuran: contain root bark of celastrus angulatus extract 5～10% emulsifying agents 10～15% antifreezes 8～10% water 65～77% manufacture methods of the present invention of dihydroagarofuran, comprise the steps:
A, with root bark of celastrus angulatus oven dry, pulverize, be transferred to extractor, add benzene and carry out refluxing extraction, the Celastrus angulatus extract;
B, the extract of steps A gained is changed in the reactor of band decompressor, is concentrated into and no longer includes solvent and flow out, emit remaining liq in the still, be and contain active insecticidal components--the extract of the polynary ester class of dihydroagarofuran;
C, get 10～15 gram extracts, add 8～12 gram emulsifier, under 80～85 ℃ of conditions, stir and add 10 gram antifreeze ethylene glycol and 63～72 gram water, through the even matter of high shear 30 minutes, promptly get the Celastrus angulatus emulsifiable concentrate again.Wherein emulsifier consists of (mass ratio): peaceful breast 34: DBS-Ca=2: 1.
D, get 5～10 gram extracts, add 10～15 gram emulsifier, under 70～75 ℃ of conditions, stir and add 8～10 gram antifreeze ethylene glycol and 65～77 gram water, through the even matter of high shear 30 minutes, promptly get the Celastrus angulatus microemulsion again.
Wherein emulsifier consists of (mass ratio): farming breast 600: OP-10: DBS-Ca=2: 4: 1.Compared with prior art, two kinds of Celastrus angulatus insecticidal preparations of the present invention--Celastrus angulatus emulsifiable concentrate and Celastrus angulatus microemulsion have the following advantages: 1. do not contain three benzene solvents, and safer to environment; 2. two kinds of preparations all with water are matrix, and are nonflammable, can store and transport safely; 3. the production cost of microemulsion and missible oil are close, and the production cost of emulsifiable concentrate reduces by 10% than missible oil, and the preventive effect of microemulsion is better than missible oil, and the preventive effect of emulsifiable concentrate and missible oil are approximate.
In June, 1998, prevent and treat the test of Chinese scholartree looper in Xi'an, ancient city.Test site is chosen in belt North Road, Xi'an, and test plant is the state Chinese scholartree of both sides, street, and reagent agent is respectively 10% Celastrus angulatus emulsifiable concentrate and 5% Celastrus angulatus microemulsion, and the contrast medicament is 10% Celastrus angulatus missible oil and 5% Celastrus angulatus missible oil.After reagent agent is converted water, plant is evenly sprayed with pesticide spray truck.Experimental result shows: 10% Celastrus angulatus emulsifiable concentrate and 5% microemulsion are diluted 1000 times respectively, 500 times, 10% Celastrus angulatus missible oil and 5% Celastrus angulatus missible oil dilute 1000 times and 500 times respectively, behind the medicine the 3rd day, the preventive effect of emulsifiable concentrate and microemulsion is respectively 92.8%, the preventive effect that 1000 times of 96.7%, 10% Celastrus angulatus missible oil and 5% Celastrus angulatus missible oil are 500 times is respectively 91.7%, 90.4%; Behind the medicine the 7th day, the preventive effect of four kinds of medicaments was followed successively by 95.1%, 100%, 95.7%, 90.9%, this shows, the preventive effect of Celastrus angulatus emulsifiable concentrate and missible oil are approximate, and the preventive effect of Celastrus angulatus microemulsion is better than missible oil.The more important thing is that said preparation does not have bad smell, environmentally safe to people and animals' low toxicity, in the urban afforestation insect protected, have good economic benefits and environmental benefit.
Fig. 1 is the technological process block-diagram of manufacture method of the present invention
The present invention can provide by following example:
Get root bark of celastrus angulatus powder (drying, whole mistake 20 mesh sieves) 25kg, add in the 250L extractor, add 100L benzene, refluxing extraction 6 hours is emitted extract, supplies novel solvent and extracts 4 hours again.Extracted twice liquid is merged, concentrate, get extract 1.76kg, productive rate 7.04%.
Get the 1.0kg extract, the peaceful breast 34 of adding 0.8kg, 0.4kg DBS-Ca under 80～85 ℃ of conditions, stirs adding 1.0kg ethylene glycol and 6.8kg water, spares matter 30 minutes through high shear again, promptly gets 10% Celastrus angulatus emulsifiable concentrate.
Get the 0.5kg extract, adding 0.3kg farming breast 600,0.6kg OP-10,0.15kg DBS-Ca under 80～85 ℃ of conditions, stirs adding 1.0kg ethylene glycol and 7.45kg water, spares matter 30 minutes through high shear again, promptly gets 5% Celastrus angulatus microemulsion.
