WE HAVE PREVIOUSLY SHOWN THAT THE FUNGICIDE mANCOZEB REDUCED bRADYRHIZOBIUM SP GROWTH BY 50%, PRODUCED BIOCHEMICAL ALTERATIONS SUCH AS CHANGES IN MEMBRANE COMPOSITION AND POLYAMINE CONTENTS, AND AFFECTED THE PEANUT-ROOT BACTERIA INTERACTION IN GREENHOUSE EXPERIMENTS. IN THIS WORK WE SHOW THE VARIATIONS CAUSED BY THE FUNGICIDE ON THE MOLECULES RELATED WITH THE PEANUT-BACTERIA INTERACTION SUCH AS LIPOPOLYSACCHARIDES AND CYCLIC b-GLUCANS. FURTHERMORE, THE CHANGES ON PEANUT ROOT NODULE POLYAMINES INDUCED BY mANCOZEB ARE ANALYZED
