REINER, Driéli Aparecida et al. By-product of the wine industry for control of Meloidogyne javanica. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.6, pp.1141-1146.  Epub 24-Fev-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i6.3016.

Wine industry by-product (WIB) is rich in bioactive compounds, including phenolics. Since root-knot nematodes are suppressed by phenolic compounds, soil amendment with WIB may control these pathogens. We evaluated the effect of wine industry by-product (WIB) on the management of Meloidogyne javanica in tomato plants in greenhouse. In the first study, potted soil was amended with 0, 5, 10, 15, 20 25 and 30 g of WIB per kg of soil. Increasing doses of WIB increased plant development. Nematode population was reduced by WIB, especially at the dose of 30 g kg-1 of soil. In the second study, a split-root experiment was designed to assess if soil amendment with WIB (30 g kg-1 of soil) induces resistance on tomato against M. javanica. WIB does not induce tomato resistance against M. javanica. This residue controls the nematode by direct contact.
