  • Publication number: 20220279780
    Abstract: 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.

  • Publication number: 20130171226
    Abstract: There has been a problem such that if a water-based pesticidal suspension containing, as an active ingredient, an agricultural chemical having a high aqueous solubility, particularly an agricultural chemical having an aqueous solubility exceeding 500 mg/L at 20° C., is stored for a long period of time, the active ingredient particles tend to grow and become coarse, whereby a stabilized suspension is hardly obtainable. To solve such a problem, the present invention provides a water-based pesticidal suspension comprising (a) an agricultural chemical or its salt having an aqueous solubility of from 500 mg/L to 6,000 mg/L at 20° C., (b) a polycarboxylate type surfactant, (c) a sulfonate type surfactant, and (d) water.
