Resumo: | The induced resistance eficiency in the control of phytopathogens is recognized, however little is known about its interference on non-target microrganisms. The present study aims to verify the induction of peroxidase activity by the use of acibenzolar-S-methyl (ASM), mannanoligosaccharide (MOS) and Bacillus cereus inductor in the control of spot blotch wheat disease and its interference on the non-target microrganism A. brasilense. The experiment was conduced under green house growing. The experimental design was made in randomized block design in a factorial schema 4 x 2 x 2, with 4 replications. The first factor "Resistance Inductors" was constituted by ASM, MOS, B. cereus inductors and water (control). The second factor "Pathogen" was constituted by the presence or absence of B. sorokiniana pathogen. The third factor "PPGR" was made up by the presence or absence of the PPGR A. brasilense. Disease severity, peroxidase activity and quantification of endofitic diazotrofic microrganisms were assessed. There was a reduction in the disease severity by the use of resistance inductors. The activity of peroxidase was estimulated by MOS inductor. Direct interference of the inductors on endophytic diazotrophic microrganisms was not observed.
