Two soil temperatures, 19 ± 1 and 27 ± 3C affected some nutrient concentrations in roots, stems and leaves of 'U. I. III' pinto bean (Phaseolus vulgaris), but did not affect overall plant morphology. Acifluorfen (5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid) at 0.84 kg ai/ha reduced N, P, K, Ca, Mg, Cu, Mn and Zn levels in each of the 3 plant tissues and also reduced pinto bean height, leaf area, root, leaf, and stem weight, and nodule wet weight compared to the nonherbicide-treated controls. Bentazon [3-(l-methylethyl)-(lH)-2,l,3-benzothiadiazin-4(3H)-one-2,2-dioxide] and sethoxydim ((2-[l-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-l-one)) generally did not affect pinto bean growth or nutrient accumulation.
