Description
Technical field
The present invention relates to a kind of compounded pesticides, more particularly, to one kind containing avermectin and azacyclotin compounding suspending agent and
Preparation method.
Background technology
Avermectin (abamectin), which has insect and mite class, tags and stomach poison function, and have faint fumigation action,
Without systemic action, but there is very strong osmosis to blade, subepidermal pest can be killed, and the longevity of residure is long, mechanism of action
It interferes nervous physiology activity, stimulation release r- aminobutyric acids unlike general insecticide, and r- aminobutyric acids are to segmental appendage
The nerve conduction of animal has inhibiting effect, small to the damage of beneficial insect.Azacyclotin (azocyclotin) is broad spectrum activity organotin mite killing
Agent, based on action of contace poison, the lasting period is long, works well to the children of tetranychid, rust mite, deutonymph, into mite, summer egg, for preventing mandarin orange
The evil mite of the crops such as tangerine, apple, hawthorn, cotton, vegetables.The acaricide is countries in the world are widely used and China's prevention is made
The acaricide that object evil mite effect is good, dosage is big.
At present, the use of the pesticidal preparations of both active ingredients is all liquid formulation, mainly based on missible oil.It is processing
A large amount of organic solvent, such as benzene,toluene,xylene are needed during missible oil.A large amount of use of organic solvent is not only caused
The waste of industrial chemicals, meanwhile, it returns environment and human health brings very big threat.In recent years, in some developed countries
Disabling part organic solvent is proposed.Therefore exploitation reduces or gets rid of the new liquid formulation of these organic solvents, has become
A kind of imperative trend, wherein preparation water baseization are exactly one of important directions of formulations of pesticide development.
Invention content
The purpose of the present invention is exactly open a kind of containing avermectin and azacyclotin compounding suspending agent and preparation method thereof.
Another object of the present invention is exactly to overcome environmental pollution of the existing technology, be detrimental to health and make
With it is of high cost the shortcomings of and a kind of water fluid for developing, it is acted on by the physical dispersion of dispersant and sand mill by Avermectin
Element and azacyclotin uniformly disperse in water, and particle average size is usually 1-3 microns, have good mobility, dispersibility, exhibition
The property and bioactivity；Convenient for measuring and using；Non-dusting in processing and use, therefore to operation and user and environment
It is all safer.
The purpose of the present invention is what is realized by following technical scheme, avermectin and azacyclotin compounding suspending agent contain Ah
Rhzomorph and azacyclotin are tieed up, by active constituent avermectin and azacyclotin and wetting dispersing agent, thickener, stabilizer, antifreeze
Agent, antifoaming agent and deionized water are configured to suspending agent, wherein the weight percent of each component is：
The wetting dispersing agent is alkyl naphthalene formaldehyde condensate sulfonates, alkylphenol-polyethenoxy base ether formaldehyde condensation products
Phosphate, alkylphenol-polyethenoxy base vinyl ethers phosphate, phenethyl phenol polyoxyethylene groups ether phosphate, polyoxyethylene polyoxy
One or more of propenyl ether block copolymer.
The thickener be one kind in xanthans, carboxymethyl cellulose, polyvinyl alcohol, bentonite, aluminium-magnesium silicate or
It is several.
The stabilizer is one or more of sodium benzoate, sodium sorbate, formaldehyde.
The antifreezing agent is one or more of ethylene glycol, propylene glycol, glycerine, urea.
The antifoaming agent is organic silicon defoamer.
Suspending agent is the formulation development using water as matrix, and there are many clear advantages：
1st, making solvent instead of organic solvent with water reduces the pollution of environment；
2nd, relative reduction production cost；
3rd, suspending agent particle is small, surface affinity is strong, opens up good penetrability, improves drug effect；
4th, using water as the dosage form of matrix, reduce packaging and the pollution in transportational process, improve safety.
Specific embodiment
Essence in order to better understand the present invention comes what the present invention will be described in detail with its theory of constitution and embodiment below
Technology contents, but present disclosure is not limited to this.
Suspending agent (SC) is a kind of new liquid formulation developed in recent years, it is using water as medium, by dispersion, emulsification
The effects that effective active component not soluble in water, by homogenizing technique, uniformly dispersed in water, form oil-in-water type
Thermodynamic stable system.Its advantage is：
1st, particle is thin；
2nd, good fluidity is easy to measure；
3rd, suspensibility is high (90%-95%)；
4th, wetability, spread, tackness are good, resistance of rainwater washing against；
5th, bioactivity is compared with WP high, and the lasting period is long compared with missible oil, and drug effect is higher than missible oil；
Without dust, without solvent, thus produce, use and store and transport that condition is relatively preferable, and environmental pollution is few, safety
It is high；
6th, there is preferable intermiscibility, convenient for being mixed with buckets such as other preparations, active constituent and auxiliary agents；
7th, processing charges is low, easy to use.
If in addition, added in suspending agent appropriate adhesive and film forming agent, warning coloration etc. can easily be made it is high performance
Pesticide seed coating；If suspending agent combines to can be made into so-called suspension emulsion and combine with microcapsules with aqueous emulsion and can be made into so-called water and hang
Microcapsule formulations etc..Particularly suitable for the effective compound of a variety of different performance active constituents；Suspending agent vulcanizes drying-granulating through spraying
It more can be made into the water dispersible granules of high comprehensive performance.
