Abstract

The metabolism of 14C-SAN-6706 [4-chloro-5-(dimethylamino)-2-(a,a,a-trifluoro-m-tolyl)-3(2H)-pyridazinone] and 14C-norflurazon [4-chloro-5-(methylamino)-2-(a,a,a-trifluoro-m-tolyl)-3(2H)-pyridazinone] were studied in cranberry plants (Vaccinium macrocarpon Ait. ‘Early Black’) for a 36-day period. Both compounds were readily translocated with progressively more label being present in the shoot portion with time. The two compounds are demethylated to the desmethyl analogue SAN-9774 (4-chloro-5-amino-2-(a,a,a-trifluoro-m-tolyl)-3(2H)-pyridazinone). Berry samples from cuttings contained no detectable radioactivity while samples from 2 year-old cranberry plants contained 20 ppb or less.
