Nematicidal Efficacy of Fluensulfone against False Root-knot Nematode (Nacobbus aberrans) in Cucumber Crop under Field Conditions | Chapter 10 | Advances and Trends in Agricultural Sciences Vol. 2
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 the lowest galling index was observed in plots treated with
fluensulfone at the same dose, with a galling index of 2.1. The results
indicated that application of fluensulfone to cucumber crop can provide good
control of N. aberrans.
