Efecto de la biofumigación con Brassica Carinata y de la solarización sobre nematodos (Meloidogyne incógnita) en el cultivo de tomate riñón (Lycopersicon esculentum)

Abstract

This research was carried out in the province of Tungurahua, Canton Píllaro, San Miguelito Parish, Valle Quillan. The objective was to evaluate the effect of biofumigation with bassica carinata and solarization to reduce the population of Meloidogyne incognita. The experiment was carried out in a greenhouse dedicated to the intensive production of kidney tomato, where the plants had nodules in the roots. In order to ensure the presence of the pathogen, a population analysis of nematodes was performed using the "Oostembrink elutriator" and "cotton filter" method in 100gr of soil resulting in a mean population of Meloidogyne incognita. The treatments were installed using the same beds of the culture in which two polyethylene gauges were added in doses of 5 and 10 kg / m2. The variables considered for the analysis were: initial and final population of nematodes and temperature. For the analysis, a split plot design was used, the main plot being the polyethylene factor, and the subplots at the dose of turnip mustard with 5 replicates. The results did not present significant differences in the treatments but if the initial sample population was reduced in relation to parasitic nematodes in contrast saprophyte nematodes increased considerably.
