The experiment was conducted in a greenhouse at the Experimental Station of Epagri, Lages, Santa Catarina State, Brazil, from 2022 to 2023. The experimental design was a complete randomised split plot design, with three repetitions, and six harvest times. Two bean cultivars were used, Perola and Campeiro. Treatments (four DHDs and distilled water as a control) were applied in main plots, while harvest times (0, 1, 6, 12, 24, and 48 hours after treat- ment) were considered as subplots. The following enzymes were ana- lysed: guaiacol peroxidase (POD), polyphenol oxidase (PPO), and catalase (CAT), in addition to the phytoalexin phaseolin. Data were analysed by analysis of variance (ANOVA) followed by Tukey?s test (p &lt 0.05). Treatment with shell limestone and Calcarea phosphorica resulted in the highest POD activity in Perola and Campeiro, respectively. PPO activity was most enhanced by Calcarea carbonica in Perola and by shell limestone in Campeiro. Calcarea carbonica also increased catalase activity in both cultivars. Phytoalexin activity was greatest with Hepar sulphur in Perola and Calcarea phosphorica in Campeiro. The use of dynamised high dilu- tions were shown as potential strategies for enhancing disease resistance  mechanisms.  aAgroecology  abiochemical mechanisms  acrop resilience  ahomoeopathic preparations  apathogenesis-related proteins1 aMATTOSA, A.
