GOMEZ, Lucila et al. SOIL BIODISINFECTION USING CIKRON-H BY-PRODUCTS. EFFECTS ON CROP. Rev. Protección Veg. [online]. 2012, vol.27, n.1, pp. 33-38. ISSN 1010-2752.

The effect of the soil bio-disinfection, using CIKRON-H by-products, on the growth of potted Lactuca sativa var BSS and Solanum lycopersicum L. var. Campbell-28 in a cropping succession was evaluated. CIKRON-H by-product was incorporated to the soil in a dose of 3kg.m²of soil^-1. A population of Meloidogyne incognita Kofoid y White (Chitwood) was inoculated to the soil, in a dose of five infestive juveniles-eggs.g^-1 of soil, to corroborate the root-knot nematode suppressive effect of CIKRON-H by-product. A completely randomized design with six treatments and five replications each was used. The total population of saprophytic nematodes after and before bio-disinfection was also recorded. Soil bio-disinfection did not affect the plant growths. The reduction of M. incognita infective juveniles in soil and root gall index were observed. It corroborates the nematicidal effect of CIKRON-H by-product against this population. The saprophytic nematode populations increased after bio-disinfection.
