Publication number: 20220279780Abstract: In order that an agriculturally active ingredient, particularly a water-insoluble or water-hardly soluble agriculturally active ingredient sufficiently exerts its effects, it is used preferably in the form of an agricultural formulation having the agriculturally active ingredient dissolved, particularly a clear agricultural formulation having not only the agriculturally active ingredient but also other components contained in the agricultural formulation dissolved. When the agricultural formulation is practically used, if foaming when diluted with water is intense, foam may overflow from a tank in which the solution is prepared. A clear agricultural formulation having the agriculturally active ingredient dissolved and further other components contained in the agricultural formulation dissolved, and its foaming when diluted with water suppressed, is required.Type: ApplicationFiled: July 27, 2020Publication date: September 8, 2022Applicant: ISHIHARA SANGYO KAISHA, LTD.Inventors: Mitsuo SANO, Takao AWAZU, Takashi OKADA, Yutaka ISHIBASHI, Yusuke KOBAYASHI
