    Abstract : The chili pepper (Capsicum annuumcapsicum annuumSubject Category: Organism Names

    L.) is vulnerable to a disease known in the state of Zacatecas as "dog's urine", which appeared recently and its importance increases every day, since it reduces the production of the pepper. Some of the symptoms are the necrosis of leavesleavesSubject Category: Anatomical and Morphological Structures

    and seeds of healthy and diseased plants were gathered in commercial plantations in Fresnillo, Calera, Villa de Cos, Villa García and Pánfilo Natera, in the state of Zacatecas; they were transferred to petri dishes viapimaricin-ampicilin-rifampin-PCNB and hymexazol (PARPH), potato dextrose agar (PDA) and water-agar culture media. The organisms that grew on leaves, stems and seeds were identifiedusing taxonomical codes. The fungi found were Alternaria solanialternaria solaniSubject Category: Organism Names

    spp. (0.2% and 0.1%), respectively; as well as saprophytic bacteria (2.5% in diseased plants). In seeds from diseased plants, there was no fungal growth found 43.2% of the plantations sampled and in healthy seeds there were saprophytic fungi (in 20%), Alternaria solani (13.5%), Aspergillus spp. (20%) and Fusarium spp. (3.3%). Based on the symptoms these pathogens cause on vulnerable plants, they were assumed to be related to the disease "dog's urine", but they do not participate directly in the production of the symptoms.
