6-Methyl-4-(3-trifluoromethylphenyl)pyridazin-3(2H)-one (T-1) was designed and synthesized based on the comparative molecular field analysis (CoMFA) of three series herbicidal 3-trifluoromethyl- 1,1 -biphenyl derivatives inhibiting phytoene desaturase. Herbicidal activities of T-1 were evaluated through barnyardgrass, rape cup tests, Spirodela polyrrhiza (L.) and greenhouse test. T-1 exhibited good herbicidal and bleaching activites. Three methods for the preparation of T-1 were reported.

Key words: phytoene desaturase, synthesis, 6-methyl-4-(3-fluorotrimethylphenyl)pyridazin-3(2H)-one, bleaching activity, herbicidal activity
