This study was mainly focused on antifungal activity of selected seven plant species viz. A. indica, A. vasica, A. sessilis, C.hirsutus, M. parvifolia, P. paniculata, and T. bellirica. The main aim of the study is to analyse the stability of extracts against C. capsici. The Ethanolic and methanolic plant extracts were treated with temperatures (50 and 100 °C) and trypsin. Efficacy of all plant extract inradial growth inhibition ofC. capsici are summarized. Significant difference was reported in growth inhibition of C. capsici, when extract was treated at 50 and 100 °C. Inhibition of radial growth of fungus after treatment with extracts at 50 °C and 100 °C has been analysing.
