Abstract
The invention aims at providing a uniformly diffusible granular pesticide preparation enabling a granular pesticide preparation which can be prepared by a simple and easy process and exert drug effects of pesticial active ingredients for a long term and is reduced in environmental load and reduced in or freed from sufferings induced by pesticidal active ingredients to be diffused uniformly over the whole of a paddy field by a simple application method. The invention provides a uniformly diffusible granular pesticide preparation which contains a non-disintegrating pesticide composition comprising an acid pesticidal active ingredient, a cationic surfactant, and a basic substance and causing no disintegration in water within 30 minutes and which has both a particle size distribution wherein the proportion of particles having diameters of 3 mm or above is 80 % by mass or above and the property of floating on water surface just after thrown onto water surface but disintegrates on water surface within 30 minutes. It is preferred that the acid pesticidal active ingredient be one having a pKa of 2 to 7, while the cationic surfactant be one having the property of gelling or swelling in water.
Description
Technical field
The invention relates in the drug effect of long-term performance pesticide activity component, can alleviate or prevent hazards of medication, reduce the uniformly diffusible granular pesticide composition of environmental pressure.
Background technology
All the time, for hazards of medication and the lasting drug effect that makes the granular agent for hydration that contains pesticide activity component obtain alleviating, all preparation methods that can suppress the pesticide activity component stripping have been studied.For example, proposed paraffin, thermoplastic resin or active carbon, granular foaming body, clay mineral composition are cooperated and the method (open clear 63-35504 communique with reference to the spy of Japan, the spy of Japan opens clear 63-45201 communique and the spy of Japan opens flat 2-288803 communique) of slowly-releasingization.
But, existing like this slowly-releasing method is not necessarily to have effect, exist the preparation method of granular agent for hydration numerous and diverse, because the release of composition pesticide is insufficient, not more than half not being used effectively of pesticide activity component and remain in the medium problem of composition pesticide, make necessary above pesticide activity component be released in the environment, the result is to the burden of the environment problem such as very big that becomes.
In addition, providing with stabilisation different active ingredients is purpose, after having prepared kernel, the preparation method's (opening flat 9-315903 communique) of granular agent for hydration who is different from the active ingredient of kernel in the coating with reference to the spy of Japan, but because the granular agent for hydration that will show slow release, makes the also not establishment of technology of the laborsaving preparation of homogeneous diffusion in whole paddy fields from the distribution on limit, paddy field etc.
Summary of the invention
The present invention is under situation like this, to provide following: can prepare with the easy method that overcomes the problem points that existing granular agent for hydration follows as problem, and in the drug effect of long-term performance pesticide activity component, can reduce environmental pressure, the granular agent for hydration of the hazards of medication that alleviates or prevent to cause owing to pesticide activity component, this granular agent for hydration are can be by the uniformly diffusible granular pesticide composition of simple distribution method in the homogeneous diffusion of whole paddy fields.
The result that present inventors study with keen determination with regard to uniformly diffusible granular pesticide composition, the non-disintegration-type granular pesticide of discovery by it being consisted of contain acid agrichemical active component, cationic surfactant to cooperate with alkaline matter, mass ratio with the above particle of particle diameter 3mm or 3mm is above size distribution of 80 quality % or 80 quality % and the character of swimming on the water surface, and 30 minutes or 30 minutes with interior disintegration in the water surface, can solve aforementioned problems, be found to be the basis with this and finished the present invention.
Promptly the invention provides:
