The Effect of Different Application Times of Some Registered Nematicides on the Root-Knot Nematode, Meloidogyne javanica
Abstract
Root-knot nematodes (RKNs) (Meloidogyne spp.) are considered the most economically important plant-parasitic nematodes (PPNs) for vegetable production, particularly for tomatoes. One control option for managing RKN is the application of nematicides, which is still widely used today. This study evaluated the efficacy of three nematicides (abamectin, fosthiazate and fluopyram) against the RKN species Meloidogyne javanica (Treub, 1885) (Tylenchida: Meloidogynidae). The nematicides were applied at five different times: three to six days before transplanting (A); just after transplanting (B); 15 days after transplanting (DAT) (C); 30 DAT (D); and 45 DAT (E). The results showed that, compared to the control (+), the lowest gall formation was observed in the following order: fluopyram (B) (1.60 ± 0.24), fosthiazate (A) (2.20 ± 0.20), and abamectin (B) (3.20 ± 0.37). The highest gall formation was observed in the abamectin (E) treatment (5.60 ± 0.24). Application of fluopyram (B), fosthiazate (A) and abamectin (B) reduced the number of second-stage juveniles (J2) by 94.62%, 91.38% and 72.88% respectively. These results point to the significance of application timing in the efficacy of nematicides and suggest that fluopyram is an effective option for the management of RKN, therefore advocating for high yields and sustainable agriculture.
