Nematicidal Efficacy of Fluensulfone against False Root-knot Nematode (Nacobbus aberrans) in Cucumber Crop under Field Conditions

Abstract

The present study was carried out to compare the efficacy of a nematicide of new generation for the control of the false root-knot nematode; Nacobbus aberrans, in cucumber crop (Cucumis sativus L.) under field conditions. The experiment was set up under a randomized complete block design with four replications. Six treatments were assessed for control of N. aberrans: four doses of fluensulfone, one of the nematicide oxamyl and a control with no application of nematicides. Ten days before transplanting, nematicides were applied in a single application via irrigation systems. Higher control under field conditions was obtained with the application of fluensulfone at a dose of 2.75 L . ha -1 . The lowest final population densities of N. aberrans in cucumber crop were recorded in the plots treated with fluensulfone at the dose of 2.25 L . ha -1 , with an average of 6.25 juveniles, and
