N-Hydrazides of 2-benzothiazolinone and their use as plant growth regulants.

摘要

N-Hydrazides of 2-benzothiazolinone have been found to be effective in regulating the growth of leguminous plants. These N-hydrazides are characterised by the formula
<CHEM>
wherein R1 is hydroxy lower alkyl or 2-benzothiazolyl; R2 is hydrogen; or R1 and R2 when taken together with the adjacent nitrogen form a heterocyclic having up to six carbon atoms, inclusive, and n is an integer from one to four.
<??>This invention relates to these N-hydrazides and their use in a method of regulating the growth of leguminous plants as well as to plant growth regulant compositions comprising these N-hydrazides.
