  • Patent number: 9485987
    Abstract: The present invention provides an aqueous suspended agricultural chemical composition comprising an agricultural chemical active ingredient, an alkyl naphthalene sulfonate formalin condensate and one or two or more compounds selected from the group consisting of an alkyl sulfate, a polyoxyalkylene alkyl ether sulfate, an alkyl phosphoric acid and a salt thereof, a polyoxyalkylene alkyl ether phosphoric acid and a salt thereof, and a polyoxyalkylene alkyl ether acetic acid and a salt thereof. The aqueous suspended agricultural chemical composition suppresses the crystal growth of the agricultural chemical active ingredient, and has an excellent effect on pest control and an excellent storage stability.
    Type: Grant

  • Patent number: 8986722
    Abstract: It is an object of the present invention to provide a pest control composition capable of exerting a high effect on pests such as spider mites and aphids even at low concentration using a food/food additive with high safety to the human body and the environment. The present inventors have intensively studied to solve the above problem and found that, among polyglycerol fatty acid esters widely used as a food additive, a composition containing a polyglycerol fatty acid ester which has an HLB of 5 or less and is liquid at ordinary temperature and also a nonionic surfactant has a high effect on pests even at low concentration, and that the possibility for pests to develop resistance to the composition is extremely low, and the present invention has been completed.
