Documented Uses

• Imazosulfuron is used to control most annual and perennial broad-leaved weeds and sedges in paddy rice and turf.
• Imazosulfuron is produced by reaction of 2-chloroimidazo[1,2-a]pyridine sulfonylisocyanate with 2-amino-4,6-dimethoxypyrimidine.
• Preparation: Y. Ishida et al., European Patent Office patent 238070; eidem, United States of America patent 5017212 (1987, 1991 both to Takeda)
• [im-(14)C]Imazosulfuron (specific activity 2.15 Gbq/mmol, radiochemical purity> 99.0%) together with unlabeled imazosulfuron (purity = 98.6%) was suspended in 0.5% carboxymethyl cellulose in ultrapure water and administered in a single dose by gavage to 3 bile duct-cannulated male Crl:CD (SD) rats. Feces, bile, and urine samples were collected at 6 and 12 hours (urine and bile only), and 24, 48, and 72 days after the administration of the dosing material. 53.4% and 30.5% of the radio-labeled dose was eliminated in
