Thiobutyric acid derivatives Abstract Novel 4-chloro-4,4-difluorothiobutyric acid derivatives of the formula I (I) in which R1 and R2 are, independently of one another, hydrogen, C1-C4alkyl or C1-C4halogenoalkyl and R3 is hydrogen or an organic radical can be employed as pest-control agents. Control of insects and arachnids is possible and preferable. |
