PROBLEM TO BE SOLVED: To provide a particulate agrochemical composition producible by a simple production method, keeping good scattering property even under a high-temperature, high-humidity condition and suppressing falling-off of the agrochemical active component from a particulate carrier and scattering (drifting) of the solid preparation itself.SOLUTION: There are provided the particulate agrochemical composition obtained by mixing (a) the agrochemical active component, (b) the particulate carrier, (c) a solid binder, (d) water and (e) a water-absorbing agent by chemical adsorption and having apparent specific gravity of 1.0-2.0, and a method for producing the particulate agrochemical composition comprising addition and mixing of (d) water to a powdery mixture of (a) the agrochemical active component, (b) the particulate carrier and (c) the solid binder which does not require a pretreatment process to form an aqueous solution or an aqueous dispersion, thereby bonding the agrochemical active component to the surface of the particulate carrier with the solid binder, and addition and mixing of (e) the water-absorbing agent by chemical adsorption to the bonded product to perform dehydration process.COPYRIGHT: (C)2011,JPO&INPIT【課題】本発明は、簡便な製造方法により製造でき、高温多湿条件下においても良好な散布性を有し、かつ、農薬活性成分の微粒状担体からの剥離および固型製剤自体の飛散(ドリフト)が抑制できる微粒状農薬組成物を提供すること。【解決手段】(a)農薬活性成分、(b)微粒状担体、(c)固体結合剤、(d)水および(e)化学吸着による吸水剤を混合してなり、見掛け比重が1.0~2.0であることを特徴とする微粒状農薬組成物および(a)農薬活性成分、(b)微粒状担体、および(c)予め水溶液化または水分散液化する前処理工程を必要としない固体結合剤の粉体混合物に、(d)水を添加後、混合して農薬活性成分を固体結合剤により微粒状担体表面に接着させ、さらに(e)化学吸着による吸水剤を添加、混合して脱水工程を行なうことを特徴とする微粒状農薬組成物の製造方法。【選択図】なし
