Abstract
This invention provides composite chinaberry insecticide and its process. The process comprises: extracting bark of chinabery to get the extracts-coarse powder of chinaberry extracts, adding composite solvent into the extracts coarse-powder to dissolve and extract them, then adding emulsifier and synergist to get the composite chinaberry insecticides. This insecticides have the advantages of good efficiency of killing pests safety for human, livestock, natural enemy of pests and other benefical animals, and the pests are not easy to have the drug resistance for this insecticide. This insecticides can be made into emulsive oil and liq. form with simple method and low cost and easy to spread.
Description
The present invention relates to a kind of compound Tomatlane pesticide and method for making thereof.
The Meliaceae plant is the focus of current research vegetable insecticide.External fruit and the leaf that mainly a kind of special Meliaceae plant " is printed chinaberry " carried out deep discussion, and fruit " chinaberry the is real " desinsection that China just began before 2,000 years with the Melia plant is cured the disease.After liberation extracting toosendanin from chinaberry makes and drives the ascarid sheet and be used for human body to drive the ascarid effect excellent.Chinese scholar has had very big breakthrough (Zhong Chaojie " solvent extraction extracts toosendanin from the immersion liquid of the melia toosendan severe edema due to hypofunction of the spleen continuously " at the method for making and the chinaberry element of research chinaberry element aspect the toxic action of pest paddy stem borer, rice weevil, corn weevil, cabbage caterpillar, mythimna separata in recent years, " Chinese herbal medicine ", 1981.12(2): 14～17); Zhang Xing " several toosendanins are obtained through refining the biologically active of product to cabbage caterpillar ", " plant protection journal ", 1989.16(3): 205-210), test, do not form product, can not widely apply in the agricultural production but these all are limited among a small circle.
Of the present inventionly be to work out a kind of good disinsection effect, nuisanceless, cheap compound Tomatlane pesticide of vegetalitas and manufacture method thereof at present.
The vegetable insecticide that insecticide of the present invention is made up of the plain thick former powder of chinaberry, double solvents, emulsifier, synergist.The shared percentage of above each component is: the plain thick former powder of chinaberry accounts for 20%; Double solvents accounts for 70%; Emulsifier accounts for 10%; Synergist accounts for 0.1%.Wherein the plain thick former powder of chinaberry is an insecticidal active ingredient, and it is the neem bark extract, contains the plain 2.5-3.0% of chinaberry.The plain pure product of its vermins-proof effect and chinaberry are suitable, so do not need to carry out purifying, not only simplified production process but also saved a large amount of solvents.Manufacture method of the present invention comprises the steps:
A. with neem bark through the hot water lixiviate, after vacuum concentration, the atomized drying, must contain the plain thick former powder of chinaberry of the plain 2.5-3.0% of chinaberry;
B. the plain thick former powder of steps A gained chinaberry is placed the extracting still, add after double solvents dissolves twice of extracting the sucking-off supernatant again;
C. the supernatant with twice extracting of step B mixes, and adds emulsifier, and synergist stirs and promptly gets compound Tomatlane pesticide;
Wherein the hot water temperature is 80 ℃ in the steps A, and each extraction time is 4 hours, and the proportion of vacuum concentration liquid is 18-20 ° of B é.
Double solvents that is adopted among the step B and content thereof are:
Dimethylbenzene 40-50%
Industrial alcohol 35-45%
Ethyl acetate 3-7%
Methyl alcohol 2-5%
The emulsifier that adds among the step C is 656H:OP-(0.5-1.0: 0.5-1.0), synergist is Dimilin.Compound Tomatlane pesticide of the present invention has the effect that poisoning, food refusal and inhibition insect growth are grown, good disinsection effect to insect.To environment, people, animal, pest natural enemy and other beneficial organism safety, insect is difficult for it is developed immunity to drugs simultaneously.The manufacture method of this insecticide is simple, with low cost, is suitable for applying.
Accompanying drawing 1 is the technological process of production block diagram of the plain thick former powder of chinaberry;
Accompanying drawing 2 is the technological process of production block diagram of compound Tomatlane pesticide.
The present invention can provide by following embodiment:
Embodiment one: take by weighing neem bark (water content is 14-15%) 1120kg, shred the long pipe nipple to 2-3cm, drop into and use hot water (80 ℃) lixiviate four times in the extractor, each extraction time 4 hours.Merge first three extract, placing vacuum concentration pot to be concentrated into proportion is 20 ° of B é, pumps into atomized drying in the spray drying tower again, gets the plain thick former powder 103.4kg of chinaberry of the loose powdery of brown, and the chinaberry cellulose content is that 2.97%(is referring to accompanying drawing 1);
Add the first material of double solvents in 500 liter electrical heating extracting stills: dimethylbenzene 150kg, industrial alcohol 105kg, ethyl acetate 9kg, methyl-sulfoxide 12kg, methyl alcohol 24kg are warming up to 65 ℃ then and stir.Drop into the plain meal 100kg of chinaberry in working order down, the insulated and stirred extracting was left standstill 20-30 minute after 60 minutes, and in high-order storage tank, supernatant extraction amount is about 250kg with supernatant liquid pump in the extracting still;
In this electrical heating extracting still, add double solvents two material again: dimethylbenzene 100kg, industrial alcohol 70kg, ethyl acetate 6kg, methyl-sulfoxide 8kg, methyl alcohol 16kg, be warming up to 65 ℃ again and stir extracting after 60 minutes, left standstill 30 minutes, extract supernatant 200kg in high-order storage tank, mix with the supernatant that extracts first;
From high-order storage tank, emit the 180kg extract in 200 liter electrical heating are mixed still, add the pure product 0.2kg of Dimilin, 656H10kg, OP-1010kg again, stirring is warming up to 45 ℃, keeps getting after 30 minutes the plain insecticidal emulsifiable concentrate 200kg(of compound chinaberry referring to accompanying drawing 2);
After this insecticidal emulsifiable concentrate adds in the entry, can form milky emulsion, after using with the spray-on process conventional spray, can be firmly stuck on the crop leaf.Can be used to prevent and treat common pest such as cabbage caterpillar, diamond-back moth, aphid, scarab beetle adult, apple skin worm, turnip sawfly, aulacophora femoralis, oriental tobacco budworm in the production.Diluted concentration is 800-1500 times during general the use, and control efficiency can reach more than 90%.After being used on the crop, the longevity of residure can reach 7-12 days, and common insect is generally come into force after using 12-24 hour.
Embodiment two: according to the method for the plain insecticidal emulsifiable concentrate of the compound chinaberry of the manufacturing of embodiment one, only need the composition and the content of levelling double solvents, can also make several composite insecticidal liquors:
The first material of double solvents content two material content
Liquid pesticide one industrial alcohol 250kg 170kg
Industrial methanol 50kg 30kg
Liquid pesticide three methyl-sulfoxide 200kg 125kg
Industrial alcohol 100kg 75kg
Liquid pesticide of the present invention can form faint yellow homogeneous liquid after adding in the entry.After the spray-on process conventional spray uses, can on general crop leaf, adhere to, but wet malleability is relatively poor when using on crops such as wild cabbage.Can prevent and treat various agricultural insect (identical with missible oil of the present invention), control efficiency can reach more than 85%.The longevity of residure can reach 5-8 days after being used on the crop, and common insect was generally come into force after 4-10 after the use hour.
