  • Patent number: 8455398
    Abstract: Amide compounds, preparation methods and uses thereof. The structure of the compounds is represented as the general formula (I), in which the definitions of substituents are illuminated as description. The present amide compounds have broad spectrum activity of killing pests and are effective on lepidopteran pests including ostrinia nubilalis, sugarcane borer, adoxophyes orana fischer von reslerstamm, apple fruit borer, grapholitha inopinata, lymantri dispar l., cnaphalocrocis medinalis, ostrinia furnacalis, helicoverpa assulta, grapholitha inopinata, plutella xylostella, spodoptera exigua, prodenia litura etc., especially for plutella xylostella, spodoptera exigua. The present amide compounds can obtain good effect at very low dosage. At the same time, some compounds have good fungicidal activity which can be used to prevent rice blast, phytophthora infestans, cucumber downy mildew or grey mold of vegetables.

  • Patent number: 8383640
    Abstract: The invention relates to substituted pyrimidine ether compounds having general formula I: The groups are as defined as specification. The compounds of formula I show high insecticidal activities for imagoes, larvae and nits of harmful acari and insects in the agricultural, civil and zoic fields, especially show excellent insecticidal activities for harmful acari such as Tetranychus cinnabarinus. Good effects can be obtained at very low dose. The compounds also exhibit preferably fungicidal activity. Wherefore, the invention also comprises the uses of compounds of formula I as insecticides, acaricides and/or fungicides in agricultural and other fields.
