Abstract SUMMARY In greenh~use experiments sone oxo6anophosphoxous, carbamate and P3xethroides pesticides tested on five ver;L’tul;le cr opu to CVU1Ulitu their e ir e c t a t different root-knot and reniform nematodes. ~sults snowed that:- A- Aldioarb, oXbmyl end phenamiphoB tit rate of (6.2~, 1).5, 20025).

B- Benomyl and mancozeb at .rate of )00 and )50 gXi.lm’ per feddan were effective in .reducing nematode popuLe t i.on .L in root and soil. The infected plant (tomato and egg -plants) t.reated’ ,,.ith both benom,l and mancoze b showed. a corxelation bet\reen the growth of plants and the .reduction in nematode population in soil.in root system and also root gall index. c- Higher dose of each nematicides were ~re effective in reducinc; the populo. tion and aup p.reaae d tilt: .’total population in both root’ and soil.
