| dc.description.abstract | The efficacy of Azadirachtan indica Neem leaf extracts were evaluated on the growth and development of P. mega aryam vitro using acetone, ethanol and methanol as extraction solvent.Fourier Tranform Infra-Red (FTIR) Spectrometer was used to determine the quantitative constituents of the plant extracts. Five levels of crude extracts concentrations were used viz; 20, 40, 60, 80 and 100% respectively to determine the best concentration at which the extract will be most effective against the pathogen.The fungus Phytophthora megakarya was isolated from infected cocoa pod. Food poisoning technique was used to determine the toxicity of the neem extracts against the grov.·th of the pathogen.5 ml of A. indica extracts were mixed with 20 ml of Potato Dextrose Agar (PDA) to get 20, 40, 60, and 80 % concentration, while the undiluted extract was recorded as I 00 %. The plates were inoculated with a 5mm assay disc cut from 7 day old culture fungus; data were taken starting from ¡ day after inoculation and the experiment was terminated at 7'h day after inoculation. | en |
