Abstract: The present invention relates to the field of pesticides. Disclosed are a pyrazole amide compound and an application thereof, and a fungicide. The pyrazole amide compound has a structure as represented by Formula (1). The pyrazole amide compound provided by the present invention has significant control effects on soybean rust, corn rust, wheat powdery mildew, cucumber powdery mildew, and rice sheath blight even at low concentration.

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.
