    Abstract: The invention relates to novel unsubstituted or substituted 2-fluorocarbonyl-2-(2,3-dihydrobenzofuran-7-yl)hydrazinecarboxylic acid esters of formula (I) wherein R1 and R2 are each independently of the other hydrogen or C1-C3alkyl, R3 and R4 are each independently of the other hydrogen, halogen, C1-C4alkyl or C1-C4-alkoxy, and R5 is C1-C4alkyl to the preparation of said compounds and to compositions containing them for use in pest control, especially for controlling insects that attack plants and animals. The novel compounds are particularly effective for controlling plant destructive sucking insects.

    IPC: A01N47/34 ,  C07C275/54

    Abstract: Novel substituted N-(p-aminophenyl)-N'-benzoyl ureas of the formula wherein each of R1 and R2 independently is C1-C4alkyl or C3-C5alkenyl, each of R3 and R4 independently is chlorine or bromine, and each of R5 and R6 independently is hydrogen, fluorine or chlorine, with the proviso that R5 and R6 are not both simultaneously hydrogen, processes for the manufacture of these compounds and compositions containing them for use in pest control, especially for controlling insects harmful to plants and animals. The novel compounds inhibit feeding damage and have in particular a pronounced ovolarvicidal and ovicidal action against plant-destructive insects.

    Inventor： EHRENFREUND J

    IPC: A01N47/34 ,  C07C275/54

    Abstract: Novel substituted N-4-(3-bromoallyloxy)-phenyl-N'-benzoylureas of the formula wherein R1 and R2 independently of one another are each hydrogen, chlorine or bromine, R3 is fluorine or chlorine, and R4 is hydrogen, fluorine or chlorine; processes for producing these compounds, as well as compositions containing them, for use in combating pests, particularly in combating insects which infest plants and animals. The novel compounds have a strong toxic and/or development-inhibiting action in particular against larval stages of insects which damage plants.

    Inventor： EHRENFREUND J

    IPC: A01N47/34 ,  C07C275/54

    Abstract: New substituted N-phenyl-N'-fluorobenzoylureas of the formula wherein R1 is a C2-C3-alkenyl group, a C2-C4-alkenyl group mono- or disubstituted by chlorine, or it is the propargyl group, R2 and R3 independently of one another are hydrogen or chlorine, and R4 is hydrogen or fluorine; processes for producing the said compounds and their use for combating pests, especially for the control of insects and representatives of the order Acarina, which infest plants and animals. The new compounds also have an antifeedant action on insects which cause damage to plants.
