Phytosanitary status of some poaceae in the Centro de Investigación Santa Lucía: case study

Abstract

Grasses are one of the most important families of vascular plants, both in terms of species diversity and economic and ecological importance. Various factors can influence the appearance of diseases in pastures, including changes in climatic conditions, soil characteristics, and inadequate management practices. Therefore, the phytosanitary analysis of forage species is essential in agriculture and livestock, since it allows the evaluation and monitoring of the health of plants intended for animal feed. The determination of phytosanitary problems in the Poaceae family at the Santa Lucía Research Center in Barrancabermeja is crucial to identify and monitor the presence of diseases that may affect the health of cultivated species. The objectives of this research were to identify the genera of phytopathogenic fungi present during the 2024 A semester at the Santa Lucía Research Center of the Instituto Universitario de la Paz, in a case study for the School of Veterinary Medicine and Animal Husbandry. The methodology included taking samples in the field using a zigzag path, storing the samples in Ziploc bags properly labeled to ensure traceability. In the laboratory, the printing technique was used to observe phytopathogenic signs. In the absence of visible signs, the samples were kept in a humid chamber for 72 hours. The identification of the genera was carried out using pictorial keys, finding the genera Curvularia, Nigrospora, and Pyricularia.
