Abstract
Abstract The effect of sulfentrazone application and combination with clomazone or pendimethalin on weed control and phytotoxicity in flue-cured tobacco was evaluated. Weed control from sulfentrazone ranged from 50 to 100% for yellow nutsedge, 17 to 100% for morningglory, 75 to 100% for pigweed, and 64 to 85% for crabgrass. Improved weed control through tank mix combinations of sulfentrazone with clomazone or pendimethalin compared to sulfentrazone alone was observed only on crabgrass. When soil moisture was low at and immediately following transplanting, weed control was reduced with a pretranspant, soil-surface treatment (PRE-T) of sulfentrazone compared to a preplant incorporated treatment (PPI). Stunting from sulfentrazone was observed at five of 18 locations. Stunting ranged from 0– 30% with sulfentrazone alone, 1 to 30% with sulfentrazone plus clomazone, and 4 to 49% with sulfentrazone plus pendimethalin. Stunting was no greater than 13% from PRE-T applications compared to a maximum of 49% with PPI ...
