ResumenLa producción de diversos cultivos hortícolas en el norte de Sinaloa, está siendo limitada por el ataque del "nematodo nodulador" Meloidogyne spp. La búsqueda de alternativas para el manejo de este fitoparasito surge como respuesta a esta problemática, entre estás el aislamiento e identificación de hongos nematófagos nativos del Valle del Fuerte. El objetivo de la presente investigación fue identificar hongos nematófagos existentes en suelos donde se producen cultivos en condiciones protegidas y susceptibles a Meloidogyne spp. El estudio se realizó de enero 2013 a julio 2014 en cuatro zonas productoras de chile c.v. Lorca Bell Pepper del Valle del Fuerte, donde se recolectaron muestras de suelo, las cuales fueron procesadas mediante el método de espolvoreado en placa (agua-agar). Para purificar y seleccionar hongos nematófagos, los aislamientos se transfirieron a placas con agar harina de maíz, identificándose las estructuras morfológicas para el diagnóstico a nivel género. Se identificaron a los generos: Dactylella, Arthrobotrys y Nematoctonus.Palabras clave: Dactylella, Arthrobotrys, Nematoctonus, hongos nematófagos. AbstractProduction of various horticultural crops in northern Sinaloa, is being limited by the attack of "root-knot nematode" Meloidogyne spp. The search for alternatives to manage this plant parasite rises as response to this problem; among the solutions is isolation and identification of native neumatophagous fungi from Valle del Fuerte. The aim of this research was to identify existing nematophagous fungi in soils where crops are grown under protected conditions and susceptible to Meloidogyne spp. The study was conducted from January 2013 to July 2014 in four producing areas of pepper c.v. Bell Pepper from Valle del Fuerte, where soil samples were collected, which were processed through the sprinkling plate method (wateragar). To purify and select nematophagous fungi, isolates were transferred to plates with agar cornmeal, identifying morphological structures for diagnostic at genus level. Identified genres were: Dactylella, Arthrobotrys and Nematoctonus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
