Abstract
El control de los nematodos fitoparásitos se ha basado principalmente en el uso de productos químicos, los cuales cada vez presentan menor eficiencia, por lo que se requiere buscar estrategias ecológicamente sustentables. Se realizaron dos ensayos para evaluar el efecto de la biofumigacion y solarización sobre las poblaciones de nematodos en el cultivo de tomate (Solanum lycopersicum) bajo condiciones de invernadero. En el primer ensayo se estudió el efecto solo y combinado de la biofumigación con la solarización en el valle Quillan, Cantón Píllaro. En el segundo ensayo se evaluó el efecto del estado fenológico de la mostaza de abisinia en el control de nematodos en suelo en la Parroquia La Matriz del Cantón Píllaro. Se observó menor efecto en el control de Meloidogyne sp. (apenas 25%), mientras que en Xiphinema sp. provocó control total. No se observó efecto de la edad del material vegetal y el tipo de aplicación sobre el número de nematodos, sin embargo, si se observó efecto por el tiempo de acción de los extractos. Basados en los resultados, el uso de brasicáceas en combinación con solarización podría ser una alternativa viable para el manejo de poblaciones de nematodos en cultivos de tomate.
The control of phytoparasitic nematodes has been mainly based on the use of chemical products, which are increasingly less efficient, so it is necessary to seek ecologically sustainable strategies. Two tests were carried out to evaluate the effect of biofumigation and solarization on nematode populations in a tomato crop (Solanum lycopersicum) under greenhouse conditions. In the first trial, the single and combined effect of biofumigation with solarization was studied in Quillan valley, Municipality of Pillaro. In the second trial, the effect of the phenological stage of the Abyssinian mustard on the control of soil-nematodes in Parroquia La Matriz, municipality of Pillaro was evaluated. Less effect was observed in the control of Meloidogyne (barely 25%), while in Xiphinema it caused total control. No effect was observed of the age of the plant material and the type of application on the number of nematodes; however, an effect was observed by the time of action of the extracts. Based on the results, the use of Brassicaceae in combination with solarization could be a viable alternative for the management of nematode populations in tomato crops.
