As the surfactant that emulsification disperses that is used for that uses among the present invention, recommendation uses wherein emulsification to disperse can not produce those surfactants of the oil droplet that bothers in dilution, concrete example comprises the castor oil ether of polyoxyethyleneization, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene styryl phenyl ether, the salt of polycarboxylic acids, the salt of dialkyl sulfosuccinate succinic acid, the salt of alkyl sulfonic acid, the salt of alkyl benzene sulphonate, the salt of lignin sulfonic acid, polyoxyethylene glycol alkyl ether, polyoxyethylene lauryl ether, polyoxyethylene alkyl ether, polyoxyethylene alkylaryl ether, polyoxyethylene fatty acid ester, the polyoxypropylene fatty acid ester, the salt of alkyl diethylene glycol (DEG) ether sulfuric acid, the castor oil of polyoxyethylene sclerosis, glycerine fatty acid fat, the sorbitan monoleate, Tween-20, the salt of poly alkyl alcohol glycol ethers polyoxyethylene alkylaryl ether sulfuric acid, the salt of polyxyethylated aryl phosphate ester, their mixture, or the like.In them, preferably nonionic surface active agent especially preferably uses Emulsifier EL-60 ether.Can suitably control the ratio that is used for the surfactant that emulsification disperses that contains in the pesticide condensed emulsion, be preferably 4.5 to 15.5 weight %, because it is if emulsified particles is too thin, then not enough to the effect of the insect of anti-IGR.
In the present invention, imidazoline surfactant is a particular importance, because it and castor oil one work, improves the effectiveness of IGR compound.Imidazoline surfactant is considered to have as the effect that suppresses the dispersant of particle association in the oil, and on the other hand, it is effective for the insect of anti-IGR that this surfactant is found.
Imidazoline surfactant includes, but not limited to Pionine C-159-ES (trade name, TakemotoOil﹠amp; Fat Co.) and Homogenol L-95 (trade name, KAO CORPORATION).In agricultural chemical of the present invention, the content of imidazoline surfactant is preferably 2 to 8 weight %.
The preferred composition of agrochemical formulations of the present invention is 1 of the IGR compound that comprises 1.25 to 12 weight %, 3.125 to 48 weight %, the pesticide condensed emulsion of the imidazoline surfactant that is used for surfactant that emulsification disperses, 2 to 8 weight % of 3-dimethyl-2-imidazolone, 4.5 to 15.5 weight % and the castor oil of 30 to 80 weight %.
Agrochemical formulations of the present invention does not need basically as polyethylene glycol of antifreezing agent etc.And, also can suitably add BHT etc. be used to prevent the stabilizing agent (antioxidant etc.) of castor oil oxidation, as synergist of piperonyl butoxide and so on etc., as 1, antifungal agents such as 2-benzisothiazole-3-ketone, colouring agent, aromatic etc.
For agrochemical formulations of the present invention, deterioration usually can take place in the material of the container of reagent bottle and so on, and this is because DMI is used to keep the IGR compound stable as aprotic solvent.In Japanese Patent Application Publication (JP-A) 2003-89603 number, a kind of methyl-sulfoxide (DMSO) and/or 1 have been disclosed, the mixture of 3-dimethyl-2-imidazolone (DMI) and antifreezing agent is as the agrochemical composition of the fabulous liquid form of storage stability, and the container of recommending use to be made by polyethylene.
But, the air-tight bottle of making by knead (knead) high density polyethylene (HDPE) or high density polyethylene (HDPE)+sealant (modification of nylon), or by high density polyethylene (HDPE) (containing calcium carbonate)/(both is by HOKUSANCO. for EVAL, LTD. manufacturing) the multilayer EVAL bottle of making, although these containers are made by polyethylene, still occur breaking in the bottle test in some cases and the phenomenon of fluid seepage.
Multilayer nylon bottle is suitable as and can stores pesticide condensed emulsion of the present invention for a long time and can not occur breaking and the container of seepage phenomenon.Especially the nylon bottle of being made up of a skin of being made by the high density polyethylene (HDPE) that contains calcium carbonate and internal layer of being made by nylon can be used as the container that stores pesticide condensed emulsion of the present invention, because this container has the durability that is particularly suitable for storing pesticide condensed emulsion of the present invention.
The pesticide condensed emulsion of the present invention that is stored in this container can not cause crystal deposition in the process that stores, can not cause fluid seepage etc. yet, and can stablize and long term storage safely.Even in the test of 72 hours low-temperature storage of-5 ℃ of storages, pesticide condensed emulsion of the present invention can not occur such as problems such as curing, crystal deposition yet.It is believed that thereby this extended storage stability is to cause owing to hygroscopicity that the appropriate balance between the composition has suppressed the IGR compound.
As the method for producing agricultural chemical of the present invention, mentioned (for example) following method among the present invention: IGR compound and Pickering agent (if required) etc. are dissolved among the DMI, add castor oil and surfactant then, obtain agricultural chemical.If desired, also can carry out filtration step.These methods can be carried out according to the description in patent documentation 1 or the patent documentation 2, perhaps carry out according to other conventional method of preparation agricultural chemical.
Agrochemical formulations of the present invention can spray according to the mode identical with general agrochemical formulations.
