Abstract
The present invention relates to N-(pyridylmethyl)-2-oxobenzothiazoline and N-(pyridylmethyl)-2-oxobenzoxazoline compounds of the formula ##STR1## wherein: T is hydrogen, alkyl containing 1 to 5 carbon atoms, halo, --CF.sub.3, --CN or --NO.sub.2 n is zero, 1 or 2; X is oxygen or sulfur; R is equal to ##STR2## their use in a method of regulating leguminous plant growth as well as compositions containing the novel compounds as the active ingredient.
Claims21
