With the purpose of identifying the micobiotic existence in plantations of plantain in a dry tropical forest in the south zone of Maracaibo Lake, Zulia state, Venezuela; the soil close to the plants in phenological stage of pre flowering was analyzed, the soil samples came from: El Canal, Santa Rosa, El Chivo, Las Rurales, Mata de Coco, El Paraiso, Dos Morales, Km 18, Puerto Concha and Janeiro. The analysis was done by using the soil dilution method until a 10-3 concentration was obtained; this last one was planted with three repetitions in Petri capsules with agar-water. Once the colonies were developed, the units of forming fungi colonies (UFC) by Petri capsule were observed and accounted. The funguses were isolated in potato dextrosa agar, with the purpose of obtaining pure culture for its identification. From the soil samples, 19 isolates were collected and identified as: Aspergillus sp., Beauveria sp., Cladosporium sp., Colletotrichum sp., Penicillium sp., Sclerotium sp., Tilletiopsis sp., and Trichoderma sp.; the quantification of UFC of fungus determined that the place, El Canal, was the one with more biodiversity comparing to other sectors. Among the isolated funguses were identified three genders Beauveria sp., Tilletiopsis sp., and Trichoderma harzianum, which are considered as potential antagonist. It was concluded that within the tested zone, the existent biodiversity is numerous, in spite of counting with dry forest conditions, this can be the result of the sample selection criteria of non technical cropping systems and none of isolated funguses within the investigation presented pathological qualities to the plantain cultivation. The genders of funguses considered as potential antagonist could be used as possible biological control agents of main pests that affect plantain crops. |
