Abstract
Abstract Nematicide trials have been conducted in Southern Italy to determine the yield response of tobacco, tomato and egg‐plant. The nematode species involved were mainly Meloidogyne incognita (Kofoid & White) Chitwood and M. arenaria (Neal) Chitwood. Many nematicides have an impact also on other soil pathogens or even on insects, so that the yied increase observed in the field has to be considered as a combined effect. On tobacco, most of the nematicides gave positive results, but it appeared that there might be important differences according to the variety considered. In certain tomato fields, which had not been specially attacked by Meloidogyne, the positive effects seemed to be also due to the insecticidal or fungicidal effect of the chemicals. No statistically significant yield increases were, however, obtained on treated egg‐plant fields.
