JP5954522B2 - Solid agrochemical composition that promotes elution into water - Google Patents

Description

  The present invention relates to a solid agrochemical composition that has improved disintegration, spreadability, and dispersibility in water and promotes elution of agrochemical active ingredients into water.

  The granular agrochemical composition is a highly safe formulation, but when the water solubility of the agrochemical active ingredient is extremely low, it is difficult to quickly dissolve the agrochemical active ingredient into the water from the granular agrochemical composition, and a satisfactory medicinal effect is obtained. It may not be possible. In order to solve these problems, it is necessary to improve the water solubility of the pesticidal active ingredient from the granular composition, and various attempts have been made.

  For example, by containing a hardly water-soluble pesticidal active ingredient having a solubility of 80 ppm or less at 20 ° C., sodium lignin sulfonate, polyoxyethylene polyoxypropylene block copolymer sodium styrylphenyl ether sulfate, bentonite and a carrier in the granules, It is known that elution is promoted (see Patent Document 1). Moreover, the elution of an agrochemical active ingredient is accelerated | stimulated by containing an agrochemical active ingredient, a polyoxyalkylene allyl phenyl ether type surfactant, a sulfonate type surfactant, and a polycarboxylic acid type surfactant in a granular composition. Is known (see Patent Document 2). Furthermore, a surfactant comprising a group selected from a) an agrochemical active ingredient, b) sodium montmorillonite, sodium carboxymethylcellulose, and c) an alkyl benzene sulfonate, a sulfosuccinic acid diester type surfactant and a polycarboxylic acid type surfactant. It is known that a decrease in particle hardness is reduced during storage under high humidity conditions by containing one of these in a granule (see Patent Document 3).

  However, even if any of the above methods is used, if the water solubility of the pesticidal active ingredient or the water solubility in the solvent is extremely low, the effect of improving the dissolution of the pesticidal active ingredient from the granular pesticide composition is still insufficient. There was a problem in practical use.
