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 ...
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
