Objective: To evaluate low- and high-dilution homeopathic products in the incidence of Moniliophthora roreri in cacao plants. Design/Methodology/Approach: The plantation was studied using a randomized block design with three repetitions and six treatments: Homeopathic nosode 12C and 200C, Cacao homeopathic combination remedy 12C and 200C, water control, and control sample, with applications every 15 days. The studied variables were: Number of flowers, number of healthy and diseased cherelles, number of healthy and diseased pods, ripe pod weight, fresh grain weight, and leaf color. Results: A significant difference was observed in the number of flowers with Cacao combined remedy 200C during November-December 2018. A significant difference was observed in leaf color with Cacao combined remedy 200C during October 2018-January 2019 and with Cacao combine remedy 12C in October 2018. No significant difference was found in treatments for number of healthy and diseased cherelles, number of healthy and diseased pods, ripe pod weight, and fresh grain weight. Study limitations/Implications: The treatment application period was short. In order to obtain more convincing results, a one-year application period prior to evaluation is suggested. Findings/Conclusions: The Cacao combined remedy 200C had a positive effect on the number of flowers during the period in which flowering decreases due to environmental conditions and on leaf greenness during four consecutive months of evaluation. Cacao homeopathic combination remedy 12C showed a significant difference for the latter variable only in October 2018. This suggests that the low-dose homeopathic medication and a high centesimal potency promotes a better response of the cacao plant to an acute disease such as moniliasis.
