Abstract:

Aglaonema, also called Chinese evergreen, is a popular and low-maintenance houseplant, which not only beautifies our home but also promotes healthier lives by cleaning pollutants from the air. Taking into consideration all these points, the demand for ornamental plants is increasing gradually. The foliage which is considered as the economic part is attacked by different diseases. The various cultural and morphological characteristics of Colletotrichum acutatum from Aglaonema were studied which were grown on different carbon containing media. Out of six carbon sources viz. Potato dextrose agar (PDA), Peptone salt agar (PSA), Czepek’s Dox Agar (CDA), dextrose in CDA medium was replaced by the same amount of sucrose (CDASWS) and lactose (CDASWL) and Oat meal agar (OMA) used for the radial growth of the fungus, it was evident that the most effective medium for rapid growth of Colletotrichum acutatum was on PSA medium followed by CDA and CDASWS media. The rate of growth was highest in PSA medium where it attained full growth in 144 hrs of incubation. Significant difference was noted in the dimensions of acervuli, setae and conidia with regards to change in media constituents, wherein it shows that OMA medium produces acervuli, conidia, setae of higher dimensions. The bioassay of three non-systemic fungicides viz. Blitox, Mancozeb and Chlorothalonil and one systemic fungicide Difenoconazole using six different concentrations along with control were examined. It was found that Difenoconazole exhibited the highest percent inhibition at EC50 value of 7.907µ/ml and lowest percent inhibition in case of Blitox with a EC50 value of 223.4µ/ml.
