In vitro evaluation of homeopathic medicines at different concentrations against the mycelial growth of Phomopsis vexans

This study evaluated the efficacy of various homeopathic medicines (Sulphur, A. montana, Phosphorus, and S. terra) at different concentrations (0.1% and 0.2%) against the mycelial growth of Phomopsis vexans in vitro. Results showed that all homeopathic treatments inhibited mycelial growth to varying extents compared to controls (inoculated and untreated). A. montana at 0.2% exhibited the highest inhibition over control (inoculated: 74.45%, untreated: 73.38%), followed by Sulphur at 0.2% (72.66% and 71.52%). Higher concentrations (0.2%) of homeopathic medicines generally showed greater inhibition of mycelial growth. The findings suggest that homeopathic medicines can be used as a safer and more sustainable alternative to chemical fungicides for managing Phomopsis vexans in brinjal cultivation. This study provides a promising approach for the management of Phomopsis vexans and promotes environmentally friendly agricultural practices.
