Study of Antifungal Activity of Geranium Oil Against Colletotrichum sp., Fusarium sp., and Macrophomina phaseolina by Poisoned Food Technique

Abstract

Geranium oil finds extensive application as a constituent in perfumes and cosmetic products. Its aromatic properties make it a popular choice for enhancing fragrances and adding a pleasant scent to various personal care items. The present study investigates the antifungal properties of geranium oil against three common fungal pathogens, Colletotrichum sp., Fusarium sp., and Macrophomina phaseolina isolated from ridge gourd (Luffa acutangula) seeds and watermelon (Citrullus lanatus) seeds by agar plate method by using the poisoned food technique. Geranium oil, known for its various biological activities, including antimicrobial properties, was tested for its efficacy in inhibiting the growth of these fungal species. The results suggest that geranium oil possesses significant antifungal activity against Colletotrichum sp., and Fusarium sp., and partial antifungal activity against Macrophomina phaseolina, providing valuable insights for its potential application in agricultural and pharmaceutical industries.
