The invention relates to haptens, conjugates, labelled derivatives and antibodies for cyprodinil. Likewise, the present invention also relates to the use of cyprodinil conjugates as test antigens or immunogens for obtaining antibodies of said fungicide, and to the use of the labelled derivatives of cyprodinil as test antigens. Furthermore, the present invention also relates to a method for analysing cyprodinil using the thus obtained antibodies, at times together with the test antigens, which are conjugates or labelled derivatives. The invention also provides a kit for analysing cyprodinil, which includes antibodies of said fungicide, at times together with test antigens, which are conjugates or labelled derivatives.
