ABSTRACT: To evaluate the potential elicitor of homeopathic preparations on bean
cv. Carioca, homeopathic preparatios Silicea and Sulphur in dynamizations 12, 24, 30
and 60CH were applied via spray throughout the shoot. Samples of leaf tissue were
taken at 6, 12, 24, 48 and 126 hours after treatment activity analysis for peroxidase. All
treatments increased the enzyme activity in at least one of the times evaluated in
comparison to the untreated control. The induction values were higher than commercial
inductor (harpin). The results indicate the potential of the treatments on induction of
biochemical mechanisms of defense in the bean.
