Abstract: Trifloxystrobin is used for the prevention and treatment of agricultural pest insects and mites. The trifloxystrobin can be configured as an agriculturally allowable emulsifiable concentrate, aqueous emulsion, aqueous solution, wettable powder, microemulsion, suspension, capsule suspension, or water dispersible granule, wherein the content of the trifloxystrobin in the dosage form is 1-80%. The trifloxystrobin has an outstanding effectiveness of control of agricultural pest insects and mites, and trifloxystrobin is a new compound, and there is no cross-resistance with existing products.

Abstract: An isoxazoline-substituted benzamide derivative, and a preparation method therefor and use thereof are provided. A compound represented by formula (I) or a salt thereof; and the compound represented by formula (I) exhibits good activity against a variety of pests and mites in agriculture or other fields. Moreover, these compounds can achieve a good control effect at low doses, and can be used in preparation of pesticides and/or acaricides and have good application prospects.

Abstract: A nematocide containing lactonic ring and a preparation method and application thereof. The nematocide containing lactonic ring includes hydrogen, cyan, fluorine, chlorine, bromine, alkyl containing 1 to 4 carbon atoms, alkoxy containing 1 to 4 carbon atoms, alkoxyphenyl, alkoxy containing 1 to 4 carbon atoms and one or more chlorine atoms in place of hydrogen atoms on the carbon atoms, alkoxy containing 1 to 4 carbon atoms and one or more fluorine atoms in place of hydrogen atoms on the carbon atoms, nitryl, and amido; R6 is selected from hydrogen, fluorine and chlorine. A result is good control effects on the eggs and second-stage juveniles of root-knot nematodes, and especially inhibition of the hatch of root-knot nematode eggs on cucumbers, tomatoes, tobaccos and soybeans, etc. The nematocide has high insecticidal efficacy and can prevent the production of antibodies in pests even after a long time of use.
