PROBLEM TO BE SOLVED: To provide an aqueous suspended agrochemical preparation with a long spraying distance from a pressure accumulation type sprayer, which can spread an active component uniformly on a large area of a paddy field even when the aqueous suspended agrochemical preparation is sprayed from a ridge and which can drop the spread agent into the paddy field without a loss because the agent hardly adheres to a rice plant.SOLUTION: An aqueous suspended agrochemical preparation contains agrochemical active ingredient, protective colloidal agent, thickener, and water, of which viscosity with a shear rate of 5,000-10,000 (l/s) at 20°C is 5-50 mPa s.COPYRIGHT: (C)2013,JPO&INPIT【課題】 蓄圧式散布機からの散布飛距離が長く、畦畔から水性懸濁農薬製剤を散布した場合でも面積の大きい水田に有効成分を均一に拡散させることができ、かつ薬剤が稲体へ付着しにくいため散布された薬剤を水田中にロスなく投下させることができる水性懸濁農薬製剤の提供。【解決手段】 農薬活性成分、保護コロイド剤、増粘剤および水を含有し、ずり速度5000~10000(1/s)における20℃の粘度が5~50mPa・sであることを特徴とする水性懸濁農薬製剤が、上記課題を解決しうる。【選択図】図1
