Description
Technical field
The present invention relates to a kind of insecticides, especially a kind of insecticides that contains Avermectin and fenbutatin oxide.

2) be a kind of non-interior miticide of inhaling, there is the harmful mite of resistance not produce cross resistance to organic phosphor and organochlorine, to doing harm to mite to tag.This medicine longevity of residure is grow in the miticide a kind of, uses all very safe at crop growth period.Use to surpass and there is no poisoning when effectively killing one times of mite concentration and take place, to young mite with become, if the lethality of mite is stronger, but little to the lethality of ovum, very little to evil mite natural enemy as influences such as predation mite, wooden dipper first and Chrysopas.
At present, the use of the pesticidal preparations of these two kinds of effective ingredients all is a liquid formulation, mainly based on missible oil.In the process of processing missible oil, need a large amount of organic solvents, as benzene,toluene,xylene etc.A large amount of uses of organic solvent not only cause the waste of industrial chemicals, simultaneously, return environment and human health and have brought very big threat.In recent years, proposed to forbid the part organic solvent in some developed countries.Therefore exploitation reduces or gets rid of the new liquid formulation of these organic solvents, has become a kind of imperative trend, and wherein water baseization of preparation is exactly one of important directions of formulations of pesticide development.
Summary of the invention
Purpose of the present invention is exactly in order to overcome environmental pollution that prior art exists, to be detrimental to health and shortcoming such as use cost height and a kind of water fluid of developing, it is dispersed in Avermectin and fenbutatin oxide in the water by the physics peptizaiton of dispersant and sand mill, the particle average-size is generally the 1-3 micron, has good flowability, dispersiveness, plate-out ability and biologically active; Be convenient to metering and use; Processing and use in do not have dust from flying, so all safer to operation and user and environment.
The objective of the invention is to realize by following technical scheme, Avermectin and fenbutatin oxide insecticides contain Avermectin and fenbutatin oxide, by active component Avermectin and fenbutatin oxide, and wetting dispersing agent, thickener, stabilizing agent, antifreezing agent, defoamer and deionized water be mixed with suspending agent, and the percentage by weight of wherein said each component is:
Avermectin 0.5～3%
Fenbutatin oxide 5～30%
Wetting dispersing agent 0.5～10%
Thickener 0.1～10%
Stabilizing agent 0.05～3%
Antifreezing agent 1～5%
Defoamer 0.5～10%
Deionized water complements to 100%
Wherein, the optimum weight ratio of component Avermectin and fenbutatin oxide is 1: 10～30; Described wetting dispersing agent is any one or more composition in alkyl naphthalene formaldehyde condensate sulfonates, alkylphenol-polyethenoxy base ether formaldehyde condensation products phosphate (SOPA), alkylphenol-polyethenoxy base ether phosphate (FLS), phenethyl phenol polyethenoxy base ether phosphate (2210), the polyoxyethylene polyoxypropylene base ether block copolymers; Described thickener is any a kind of in xanthans, carboxymethyl cellulose, polyvinyl alcohol, bentonite, the aluminium-magnesium silicate; Described stabilizing agent is one or more in Sodium Benzoate, sodium sorbate, the formaldehyde; Described antifreezing agent is one or more of ethylene glycol, propane diols, glycerine etc.; Described defoamer is silicone based; The formulation that said composition is prepared can also be a water dispersible granules.
Suspending agent is to be the formulation development of matrix with water, and many tangible advantages are arranged:
1, replaces organic solvent with water and done the pollution that solvent has reduced environment;
2, reduced production cost relatively;
3, the suspending agent particle is little, surface affinity strong, opening up good penetrability, has improved drug effect;
4, be the formulation of matrix with water, reduced the pollution in packing and the transportation, improved safety.
Embodiment
Essence for a better understanding of the present invention describe technology contents of the present invention in detail with its theory of constitution and embodiment below, but content of the present invention is not limited to this.
Suspending agent (Suspension Concentrates) is a kind of new liquid formulation of developing in recent years, it is medium with water, act on water-fast effective active component by dispersion, emulsification etc., by homogenize technology, it is dispersed in the water, forms the thermodynamic stable system of oil-in-water type.Its advantage is:
(1) particle thin (VMD1-3 micron);
(2) good fluidity is easy to metering;
(3) suspensibility height (more than the 90-95%);
(4) wetability, spread, tackness are good, resistance of rainwater washing against;
(5) biologically active is than the WP height, and to compare the lasting period long with missible oil, and drug effect is higher than missible oil;
(6) no dust, do not contain solvent, thereby produce, use relative with the storing condition better, environmental pollution is few, and is safe;
(7) intermiscibility is preferably arranged, be convenient to mix with buckets such as other preparations, active component and auxiliary agents;
(8) processing charges is low, and is easy to use.
In addition, can make high performance agricultural chemicals kind clothing agent (FS) easily if add suitable adhesive and film forming agent, warning colouration etc. in the suspending agent; Suspending agent can be made into the outstanding microcapsule formulations (ZC) of so-called water etc. if can be made into so-called suspension emulsion (SE) with aqueous emulsion (EW) combination with microcapsules (CS) combination.Be particularly suitable for the effectively compound of multiple different performance active component; Suspending agent more can be made into the water dispersible granules (WG) of high comprehensive performance through the spray-fluidized-bed drying granulation.
