Title: N-Substituted oxobenzothiazoline and oxobenzoxazoline derivatives and their use as plant growth regulants

Abstract: The present invention relates to compounds of the formula ##STR1## wherein X, Y and W represent independently oxygen or sulfur; T represents lower alkyl, lower alkoxy, halo, CF.sub.3 or NO.sub.2 ; m is an integer of from 0 to 2; n is an integer of from 1 to 3; and R is selected from the group consisting of ##STR2## morpholino, pyrrolidyl, pyrrolidyl substituted by from 1 to 2 lower alkyl or lower alkoxy moieties and ##STR3## where a is an integer of from 5 to 8 inclusive; R.sub.1 represents lower alkyl, lower alkenyl, benzyl, phenyl or phenyl substituted by from 1 to 3 lower alkyl, lower alkoxy, lower alkenyl, CF.sub.3 or NO.sub.2 moieties; R.sub.2 represents hydrogen, lower alkyl or lower alkenyl moieties, with the proviso that when X is oxygen, R.sub.1 and R.sub.2 cannot equal methyl. The invention also relates to the use of said compounds in a method of regulating leguminous plant growth as well as to plant growth regulant compositions.
