During the crop cycle, the diseases incidence caused by fungi mainly the burn or leaf blight, it was increased, for this reason, it is necessary the “MORPHOLOGICAL CHARACTERIZATION OF THE PHYTOPATHOGENIC FUNGUS IN CARROT CROP (Daucus carota L.), AT SAN BUENAVENTURA SMALL TOWN IN COTOPAXI PROVINCE DURING 2014”. It is important for proper crop management, so that it allows preventing this disease has a significant effect on performance. The objective of this research was been to morphologically characterize the fungus that causes the greatest impact on crop production carrot (Daucus carota L.), that it was affected to this disease. It was carried out the isolation of the diseased plant tissue in petri boxes that they were contained the medium crop Potato - Dextrosa - Agar (PDA) and it was proceeded to incubate to 23º C, to observe the development of fungus mycelium fungal that it was carried out four days, then it was proceeded to perform the purification using the crop technique of hypha tip. It was sowed again in petri boxes with PDA + 2% of citric acid, and incubated at 23 ° C for 10 days. The crops obtained were compared with the information available in the database, using bibliography and photos. |
