Abstract

Weeds are one of the main factors that limit the production of coffee cultivation (Coffea arabica L.), they can also host pests and diseases. The objective of this work was to determine the fungi and nematodes present in the weed community associated with coffee cultivation in the central jungle of Perú. For the extraction of the nematodes, the "Baerman tray method" (soil) and the "blender method" (roots) were used. In the case of fungi, the usual techniques for the isolation of phytopathogenic fungi in a Phytopathology laboratory. The host weeds of pathogens found in this study belong to the families Asteraceae, Poaceae, Amaranthaceae, Rubiaceae, Pteridaceae and Araceae. The genera of phytopathogenic fungi found were Cercosporodium, Cercospora, Colletotrichum, Stagonospora, Mycosphaerella, Cercosporella, Phoma, Polythrincium and Didymella. The genera of phytopathogenic nematodes found were Meloidogyne, Helicotylenchus, Paratylenchus, Xiphinema, Tylenchulus, Tylenchus, Dolichodorus, Aphelenchus, Aphelenchoides. In addition to a species of Criconematidae, a Trichodoride and a Heteroderidae. Nematodes of free life were also found.
