Description
Technical field
The invention belongs to agricultural pesticide field, and in particular to a kind of emamectin benzoate benzene first of suppression chitin synthesis
Hydrochlorate mite killing suspending agent and preparation method thereof.
Background technology
It is current main to use chemical pesticide control agricultural pest, but over time, the drawbacks of chemical pesticide by
Gradually it is exposed, of particular concern is the rampant and resistance problem mad again of residues of pesticides, insect, these problems promotes people to open
Beginning finds the substitute of chemical pesticide.AVM is that antibioticses desinsection kills full mite agent, belongs to biological source insecticide, with chemistry
Unlike agricultural chemical insecticide, AVM mainly by disturbing insect nervous physiology activity, stimulates release GABA,
And aminobutyric acid has inhibitory action to the nerve conduction of arthropod, mite class adult, nymph and insect larvae and AVM connect
There is paralysis symptom after touch, inertia, do not take food, it is dead after 2~4 days.AVM is to insect predator and insect parasite
Though there is direct action of contace poison, because plant surface residual is few, therefore to the damage very little of beneficial insect.AVM is in soil by soil
Absorption will not be moved, and can be decomposed by the microorganisms, thus in the environment without cumulative function.Due to not causing insect to take off rapidly
Water, AVM lethal effect is more slow.
Author Chen Fuliang exists《The development of the avermectin micro-emulsion containing organosilicon auxiliary agent》In one text, with 7% Avermectin
Element, 6% cyclohexanone, 4% dimethyl sulfoxide (DMSO), 5% organosilicon auxiliary agent Silwet408 and balance of water, are obtained AVM micro-
Emulsion；Addition organosilicon auxiliary agent can not only significantly reduce liquid surface tension and improve liquid blade surface wetting,
Ability is opened up, increases the expanding area of liquid, and liquid can be made to enter hidden close insect hiding place, and promote plant leaf surface pair
The absorption of active ingredient and enter epidermis, extend its lasting period；But active ingredient is single Avermectin in the microemulsion
Element, its Insecticiding-miticiding is inefficient, and lethal effect is slow.
The content of the invention
It is an object of the invention to provide the emamectin benzoate benzene of a kind of efficient and lasting suppression chitin synthesis
Formates mite killing suspending agent and preparation method thereof.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of emamectin-benzoate mite killing suspending agent for suppressing chitin synthesis, it is characterised in that it is by as follows
The raw material of weight portion is prepared from：Emamectin benzoate 6-8 parts, methyl alcohol 120-150 parts, phosphoric acid solution 30-40 parts, toluene
200-250 parts, isopropyl acetate 60-70 parts, fatty acid monoglyceride 2-3 parts, benzoic acid 12-15 parts, n-hexane 180-200

In the solution put, after mixing and stirring, the solution of polyethylene glycol and atoleine configuration is added to, in 50-55 DEG C of water-bath
In turned with 2200-2500/the rotating speed constant temperature of min quickly stirs 25-30min, forms white " milky " liquid, leads to nitrogen 20-30min,
The solution of Geniposide and the configuration of remaining acetone is added, 65-70 DEG C is continued to stir 5-6h, is washed with deionized 2-3 times, from
The heart is separated, and 20-24h is dried in 60-65 DEG C of vacuum drying chamber, and the shitosan for obtaining loading emamectin-benzoate delays
Release microballoon；
（4）By step（3）Product, citric acid dibutyl naphthalenesulfonic acid calcium is added to equivalent to step（3）Products weight part 15-
In 20 times of deionized water, ultrasonic disperse 30-40min adds palmitic acid formicester, triethanolamine, with 800-1000 turns/min's
Rotating speed stirs 25-30min, the emamectin-benzoate mite killing suspending agent of the chitin synthesis that are inhibited.
The emamectin-benzoate mite killing suspending agent of described suppression chitin synthesis, it is characterised in that institute
The concentration of the phosphoric acid solution stated is 0.5-0.6mol/L.
Beneficial effects of the present invention are：
The present invention is main acaricide with emamectin-benzoate, and compared to AVM parent, it is to Lepidoptera elder brother
The activity of worm larva is generally improved, and is especially 6 times of AVM to the preventing and treating of acarid；Emamectin-benzoate
Belong to biogenic pesticide, with its unique mechanism of action, be difficult to remain, can be biodegradable, it is safe and environment-friendly the advantages of, meet
Develop the requirement of nuisanceless fruits and vegetables, pollution-free food；Present invention addition diflubenzuron, work is cooperateed with emamectin-benzoate
Can suppress the synthesis of chitin on larva body wall with, diflubenzuron, ovum is unable to normal development, the larva epidermis of hatching lack hardness and
It is dead；The present invention wraps up AVM using shitosan, and obtains sustained-release micro-spheres, not only to chitosan crosslinked using Geniposide
The slow release medicine of energy, extends the service life of medicament, can significantly reduce its resolution ratio in storage, and shitosan energy
Promote medicament to be absorbed by plants rapidly through Stoma of Leaves, further increase miticidal effect；Mite killing suspending agent of the invention can be efficient
