IF X is oxygen, R represents an alkoxyalkylene, alkylmercaptoalkylene or alkenyloxyalkylene radical with at most 7 carbon atoms, an alkenyl radical with 3 to 6 carbon atoms or an unsubstituted benzyl group or a benzyl group which is substituted by halogen, methyl and/or methoxy, or wherein B. IF X is sulphur, R represents an alkenyl radical with 3 to 6 carbon atoms or an unsubstituted benzyl group or a benzyl group substituted by halogen, methyl and/or methoxy; these compounds are useful for defoliating and promoting the ripening of crop plants especially cotton.
