Research Notes : United States : Response of soybean strains to DPX-F6025 in hydroponics
Introduction: Previous work with DPX-F6025 (2-(([(4-chloro-6-methoxy-pyrimidine-2-yl) amino carbonyl] amino sulfonyl)) benzoic acid, ethyl ester) found differential strain response to increasing rates in hydroponics (Lloyd, 1985). Hanson (1984) reported differential strain response to a single rate of metribuzin in soybeans when evaluated in a hydroponic system similar to one developed by Barrentine et al. (1976). With known agronomic changes in soybeans associated with herbicide treatments, this study was undertaken to study the agronomic effects of DPX-F6025 on a randomly selected group of soybean strains when evaluated in a hydroponic system.
