A NOVEL NEMATICIDE FOR THE CONTROL OF ROOT-KNOT NEMATODES IN TOMATO CROP

José A. Calvo-Araya

Abstract


A novel nematicide (fluensulfone) was evaluated for control of the root-knot nematode Meloidogyne incognita in tomato crop (Solanum lycopersicum L.) under field conditions. The experiment was set up in a randomized complete block design with four replicates. Six treatments were assessed for control of M. incognita: four doses of fluensulfone, one dose of the nematicide oxamyl, and a control with no application of nematicides. Ten days before transplanting, nematicides were applied in a single application via an irrigation system. The lowest final population densities of M. incognita in tomato crop were recorded in plots treated with fluensulfone at the dose of 2.75 L·ha-1, with an average of 26 juveniles. The higher percentage of efficacy was obtained with the application of fluensulfone at a dose of 2.5 L·ha-1. Fluensulfone exerted a more efficient nematicidal activity as compared with oxamyl, which is the most used nematicide in crops in Mexico. Our results indicated that fluensulfone can be used as an alternative nematicide for the control of M. incognita in tomato crop and other crops.
