Carfentrazone at 0.0125 and 0.025 lb AI/A was safe on all three lettuce cultivars. No stand reduction was observed. Sulfentrazone confirmed the initial screening test rate range of 0.05 to 0.1 lb AI/A for demonstrating marginal lettuce safety. Flumetsulam and thifensulfuron showed greater selectivity only in head lettuce while severely injuring romaine and red leaf lettuce. Rimsulfuron caused considerable stand reduction of all three lettuce cultivars. Sulfentrazone, fluroxypyr, and thifensulfuron exhibited good tolerance on broccoli as no stunting or stand reduction was observed at maturity.
