| Abstract: |
Solanum tuberosum (Potato) is one of the most important tuber crops with the production of 315
million tons worldwide per year. In the present study an attempt has been made to screen and
· evaluate the antifungal activity of plant extracts against the fungal pathogens of potato plant.
Crude ethanolic extracts of five different plant materials viz. Brassica nigra (cake), Cinnamomum
camphora (fruits), Eupatorium adenophorum (twigs), Lantana camara (twigs) and Melia
azedarach (fruits) were screened and tested against the three fungal isolates (Phytophthora
infestans, Alternaria so/ani and Fusarium oxysporum) from diseased potato leaf samples. The
antifungal activity of the crude extracts obtained was evaluated by agar well diffusion method and
two fold broth dilution method. C. camphora gave the highest yield of700/6 while M azedarach had
the lowest yield of 9. 7 5% of crude extracts. B. nigra was found most effective against P. infestans
with both MIC and MFC values 6.15mg/ml. Similarly, M azedarach showed the higher antifungal
activity against A. so/ani with both MIC and MFC values 3.115mglml. C. camphora was found
least effective against P. infestans and A. so/ani while it was most effective against F. oxysporum
with both MIC and MFC values 3.115 mg/ml. Different types of plant extracts with different
concentration significantly inhibited the growth of all the fungal pathogens at P (<0.05). The
extracts used in this experiment were found to be suitable for the control of these fungal pathogens. |
