【 摘 要 】

The objective of this work was to evaluate the effects of the herbicides glyphosate, fluazifop-p-butyl and fomesafen, applied by different methods, on nodulation and initial growth of two glyphosate-resistant (GR) soybean varieties. Treatments were arranged in a 6 x 2 factorial, with six herbicide application methods (no-herbicide check, fomesafen/fomesafen sequential application, fomesafen/[fomesafen+fluazifop-p-butyl sequential application], fluazifop-p-butyl single application, glyphosate/glyphosate sequential application and glyphosate single application) and two soybean varieties (BRS 245 RR and BRS 247 RR). Regarding soybean nodulation, fomesafen/fomesafen sequential application was the most selective herbicide application method. Variety BRS 245 RR was more tolerant than BRS 247 RR to the herbicides evaluated. Number and dry weight of nodules decreased after single applications of fluazifop-p-butyl and glyphosate.
