ABSTRACT:
Pyridazinylurea N-oxide plant regulators of the formula ##STR1## and acid addition salts thereof; wherein R is alkyl, cycloalkyl or phenyl optionally substituted with halogen; R.sup.1 is hydrogen or alkyl; each X independently is halogen, alkoxy, alkylthio or alkylsulfonyl; p is 0, 1 or 2; and wherein the NHCONRR.sup.1 group is bonded to the pyridazinyl ring in the 3- or 4-position; provided that (a) when X is halogen, p is 1 or 2 and the NHCONRR.sup.1 group is in the 4-position, the halogen is in at least one of the 5- and 6-positions, and (b) when X is halogen, p is 1 or 2 and the NHCONRR.sup.1 group is in the 3-position, the halogen is in at least one of the 4- and 5-positions.
