BACKGROUND: 4‐(3‐Trifluoromethylphenyl)pyridazine represents a new series of compounds with bleaching and herbicidal activities. RESULTS: A total of 43 novel 3‐(substituted benzyloxy or phenoxy)‐6‐methyl‐4‐(3‐trifluoromethylphenyl)pyridazine derivatives were synthesised, and their bleaching and herbicidal activities were evaluated through Spirodela polyrrhiza and greenhouse tests. Some compounds exhibited excellent herbicidal activities, even at a dose of 7.5 g ha−1. CONCLUSION: The results showed that a substituted phenoxy group at the 3‐position of the pyridazine ring and the electron‐withdrawing group at the para‐position on the benzene ring were essential for high herbicidal activity.
