Chemical management of root-lesion nematode, Pratylenchus neglectus in two Idaho potato fields

S. L. Hafez, P. Sundararaj

Abstract


Three field trials were conducted in Idaho, USA, to study the efficacy of oxamyl (Vydate C-LV), aldicarb (Temik 15G) and ethoprop (Mocap 6EC) for control of lesion nematode on potato. In the first trial there was an increase in saleable yield and total yield of potato tubers in all treatments with oxamyl and aldicarb compared to the control plots. Saleable yield was significantly increased by oxamyl (Vydate C-LV at 2.2 kg/ha) and aldicarb (Temik 15G at 22 kg/ha) applications compared to the control and Vydate C-LV (1.2 kg/ha). In the second and third trials, although there was no significant difference among treatments in saleable yield, the total yield was significantly increased by all oxamyl and aldicarb treatments compared to the control plots.
