ANTIFUNGAL ACTIVITIES OF ZINNIA ELEGANS AND PLECTRANTHUS RUGOSUS LEAVES AGAINST ROT CAUSING FUNGI

Jahangir Abdullah Koka*, Abdul Hamid Wani and Mohd Yaqub Bhat

ABSTRACT

The ethanolic and aqueous leaf extracts of Zinnia elegans L. and Plectranthus rugosus Wall ex Benth were evaluated for their antifungal activities on rot causing fungi, viz. Penicillium expansum, Aspergillus niger, Mucor plumbeus, Alternaria alternata, Penicillium chrysogenum, Trichothecium roseum and Rhizoctonia solani isolated from rotten tomatoes and brinjal using the agar well diffusion method. All the concentration of plant extracts showed antimycotic activity against tested pathogenic fungi. Antimycotic activity increased with the increased concentrations of plant extracts. However, higher concentrations proved more effective than lower concentrations. It was revealed from the present study that the ethanolic extract of Zinnia elegans showed maximum antimycotic activity against Trichothecium roseum and least activity against Alternaria alternata. However, the aqueous extract of Zinnia elegans showed maximum antifungal activity against Trichothecium roseum and least activity against Rhizoctonia solani and Alternaria alternata. It was further revealed from the present study that the ethanolic extract of Plectranthus rugosus showed maximum antimycotic activity against Aspergillus niger and least activity against Mucor plumbeus. Whereas the aqueous extract of Plectranthus rugosus showed maximum antimycotic activity against Aspergillus niger and least activity against Penicillium expansum.
