  • Patent number: 9848601
    Abstract: To provide a pesticidal composition having a stable and high pesticidal effect. The pesticidal composition comprises a pyridine compound represented by the formula (I): (wherein R1 is CH2CN or and each of R2 and R3 which are independent of each other, is a hydrogen atom, a halogen atom, C1-6 alkyl or C1-6 alkoxy) or its salt and at least one potency-enhancing component selected from the group consisting of a nonionic surface active agent, an anionic surface active agent, a cationic surface active agent, an amphoteric surface active agent, an animal or plant oil, a mineral oil, a water-soluble polymer, a resin and a wax.

  • Patent number: 9642357
    Abstract: To provide an oil-based pesticidal suspension which suppresses foaming at the time of preparation of a spray liquid by an organic silicone type surfactant, and which has excellent pesticidal activity with a small amount of an agricultural chemical. The present invention provides an oil-based pesticidal suspension comprising (1) flonicamid or its salt, (2) an organic silicone type surfactant and (3) at least one oil-based diluting agent selected from the group consisting of a vegetable oil and its alkylated oil, and a method for controlling pests, which comprises applying the oil-based pesticidal suspension to the pests or to a place where they grow.
