GOMEZ, Lucila et al. USE OF BIOFUMIGATION FOR THE MANAGEMENT OF Meloidogyne spp.INVEGETABLE SHELTERED PRODUCTION. Rev. Protección Veg. [online]. 2010, vol.25, n.2, pp. 119-123. ISSN 2224-4697.

The effect of soil biofumigation on Meloidogyne spp. during two crop cycles (tomatocucumber) grown under sheltered conditions was evaluated. Semi-rotted cattle manure, used as the biofumigation material, was incorporated in the soil of the plots at a dose of 10 kg.m of soil. Before and after biofumigation, the soil infestation index of Meloidogyne spp. was determined in soil samples taken along the five plots of the tunnel using the indirect bioassay method. The seeds of both tomato and cucumber crops were pelleted with ECOMIC(10% of seed weight) and FITOMAS (3 mL.L of water) before the seedbeds were set up. The entire root system of each crop was removed from the soil at the end of the harvest. The gall index in the root system of both crops was evaluated. The yields of each crop were also recorded as kg of product per tunnel. The infestation level of the soil after biofumigation decreased from 4,8 to 1,8 degree. The gall index at the end of each crop cycle was always below three. The yields achieved in both crops were 50% higher than those obtained in these crops before this experiment. The results of this work confirm that soil biofumigation is a practicable alternative for the management of the root-knot nematode Meloidogyne spp. in the vegetable production under sheltered conditions.
