Zusammenfassung:	Pyridazine derivs. of formula (I) are new. R1, R6 = 1-4C alkyl, or Ph or naphthyl both opt. substd. by 1-3 halogen, trihalomethyl, 1-4C alkoxy, 1-4C alkyl or CN; R3, R5 = COOM, (1-4C) alkoxycarbonyl or CONR'R''; M=H or alkali metal; R1 = H or 1-4C alkyl; R'' = 1-4C alkyl. (I) are plant growth regulants and are esp. useful as chemical hybridization agents in graminaceous crops because they can induce selectively male sterilization. They are also useful for the control of flowering and fruit-bearing, and for the inhibition of seed formation in non-cereal specvies.
