Abstract

Synthetic fungicides have been used to control fungal diseases. Although, synthetic fungicides are highly effective, their repeated use has led to problems such as environmental pollution, development of resistance and residual toxicity. Plant extracts have been known for their medicinal and antimicrobial properties since ancient times and the antifungal action of plant extracts has gained much attention. Nowadays, plants are being used against many pathogenic fungi. Green plants are huge reservoirs of various effective chemotherapeutic agents and could serve as an environmentally friendly natural alternative to most toxic synthetic agents. Six different fungal species belonging to four genera were repeatedly isolated: Fusarium oxysporum, Aspergillus carbonarius, Aspergillus niger, Phytophthora infestans, Fusarium monoliforme, Phanerochate carnosa. The zones of inhibition of the four synthetic fungicides (Nystatin, Ketoconazole, Fluconazole, Clotrinazole) ranged from 13mm to 40mm. Some fungal strains were resistant to some of them, with the exception of Nystatin. The oils (Eucalyptus, Olive, Castor) and plant extracts (Neem, Garlic, Ginger, Aloe) {botanicals} also showed impressive antifungal potentialities, with their zones of inhibition ranging from 17mm to 46mm, thus making them comparatively efficacious as their synthetic counterparts. The botanicals employed revealed the presence of different phytochemicals, including alkaloids and tannins, which could have been responsible for their potency. Prolonged usage of synthetic fungicides pose health problems as modern society is becoming health conscious; therefore, botanicals could be more cheaply commercially produced and made available in presentable forms.
