The present investigation was carried out in the province of Quillota, V Región, Chile. The principal objetives were to evaluate the effect of some nemacides in the control of parasitic nematodes and the yield of tomatoes (Lycopersicon esculentum M.). The tratments were: DD, 495 l/ha A. I.; DBCP, 26.25 l/ha A. I.; Agricur 10% G, 20 Kg/ha A. I.; Nemacur 10% G, 20 Kg/ha A. I.; Basamid, 425 Kg/ha A. I.; VPM, 98.1 l/ha A. I., and control without treatment.The experimental desing consisted of a complete randomized block desing, with 4 repetitions. The data for nematode control, degree of rootknot nematode (Meloidogyne spp) infection and yied, was significant at 0.05.
The Duncan Test showed that in nematode control and yield there were no significantdiferences in nemacide treatments; but these differences were significantwith the control.Some of the nemacides used had herbicide action and others had insecticide action.None had phytotoxic effect.DD, 495 l/ha A. I. and 425 Kg/ha A. l. of Basamid gave the highest yields,with 89.3 and 84.0 Ton/ha, respectively.
