CHEMICAL ESSAY ON TOMATO FRUIT BORER Neoleucinodes elegantalis (Guennée, 1854)

A trial was carried out in Goiânia-Go, Brazil, to verify the effect of several insecticides on tomato fruit borer Neoleucinodes elegantalis (Guenné, 1854). The treatments and active ingredient per hectare were: 1-cypermethrin, 130 g; 2-diclorvos, 312.5 g; 3- diazinon 250 g; 4- diazinon 30 g and 5- cartap 312.5 g. The experimental design used was randomized blocks, with four replications being each plot constituted of two rows with 10 plants. The insecticides were applied four times at seven days intervals. The results showed that all the treatments were efficient to control the tomato fruit borer. The best results were obtained with cartap, 90.9% of the control, followed by cypermethrin with 88.2% of control.
