Abstract
The present invention provides composite toosendanin insecticide and a preparation method thereof. The composite toosendanin insecticide is prepared by the following steps: a composite solvent is added to coarse initial powder of toosendanin, which is the extract of neem barks, and after the coarse initial powder of toosendanin is dissolved and extracted, an emulsifier and a synergistic agent are added. The insecticide of the present invention has the advantage of good disinsection effect and is safe for environment, people, livestock, the natural enemies of insect pests and other beneficial animals, and the insect pests are not easy to have insecticide resistance. The insecticide can be made into an emulsifiable solution or liquid. The insecticide has simple preparation method and low cost and is suitable for popularization and application.
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 or margosine (being referred to as the chinaberry element) from Melia plant melia toosendan (Melia toosendan) and China tree (Meliaazedarach) bark 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.
The objective of the invention is to work out a kind of good disinsection effect, nuisanceless, cheap compound Tomatlane pesticide of vegetalitas and manufacture method thereof.
The vegetable insecticide that insecticide of the present invention is made up of the plain thick former powder of chinaberry, double solvents, emulsifier, synergist.More than the shared percentage of each component be: the plain thick former powder of chinaberry accounts for 19.98%; Double solvents accounts for 69.93%; Emulsifier accounts for 9.99%; Synergist accounts for 0.10%.Wherein the plain thick former powder of chinaberry is an insecticidal active ingredient, and it is the neem bark extract, contains chinaberry element 2.97%.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 is included in following 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 chinaberry element 2.97%;
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 clear liquid 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 is 18～20 ° of B é.
Double solvents that adopts among the step B and content thereof are:
Dimethylbenzene 0～50%
Industrial alcohol 35～100%
Ethyl acetate 0～3%
Methyl alcohol 0～16%
Methyl-sulfoxide 0～65%
The emulsifier that adds among the step C is 656H: (0.5～1.0: 0.5～1.0), synergist is a diflubenzuron to OP-10.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 a process flow block diagram in the production of the plain thick former powder of chinaberry.
Accompanying drawing 2 is the technological process of production block diagram of compound Tomatlane pesticide.
Embodiment one: take by weighing neem bark (water content is 14～15%) 1120kg, shred long pipe nipple to 2-3cm, drop in the extractor with hot water (80 ℃) lixiviate four times, 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, get the plain thick former powder 103.4kg of chinaberry of the loose powdery of brown, the chinaberry cellulose content is 2.97% (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, disulfoxide 12kg, methyl alcohol 24kg are warming up to 65 ℃ then and stir.Drop into down the plain meal 100kg of chinaberry in working order, insulated and stirred extracting 60 minutes was left standstill 20～30 minutes, with supernatant liquid pump in the extracting still in high-order storage tank.Supernatant extraction amount is about 250kg;
Add double solvents two material again in this heating extracting still: dimethylbenzene 100kg industrial alcohol 70kg, ethyl acetate 6kg, methyl-sulfoxide 8kg, methyl alcohol 16kg are warming up to 65 ℃ again and stir extracting 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 diflubenzuron, 656H10kg, OP-10 10kg again, stir and be warming up to 45 ℃, keep getting after 30 minutes the plain insecticidal emulsifiable concentrate 200kg (referring to accompanying drawing 2) of compound chinaberry;
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, chafer 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 hours.
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 liquid pesticide one double solvents content two material content industrial alcohol 250kg 70kg industrial methanol 50kg 30kg liquid pesticides 2 75% industrial alcohol 300kg 200kg liquid pesticides 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, 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 after the use 4～10 hours.
