Abstract

Abstract Phosphoric acid esters of the formula D R A W I N G WHEREIN X denotes oxygen or sulphur, the integer n is the number 0 or 1, R'' and R'''' independently of each other represent an alkyl radical with 3 to 5 carbon atoms and wherein a. if X is oxygen, R represents an alkoxyalkyl, alkylmercaptoalkyl or alkenyloxyalkyl 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.
