Abstract

Four (4) sites or area were sampled, using the”simple random sampling technique” to make up the study group namely; Malali, Ungwan Rimi, Stadium round about, Kawo for soil or root-not nematodes from tomatoes plant. Ten (10) plants uprooted randomly at each site(s) visited making a total of forty (40) plants were isolation and identification of nematodes was done at the Department of Crop Protection, Institute of Agricultural Research (I.A.R.) Ahmadu Bello University Zaria base on movement action, tail, shape and a tutorial book. Result obtained shared occurrence of nematodes as follows; Malali, 342; Ungwan Rimi 40; Stadium Round About, 66; Kawo, 261; making a total of 708 nematodes. Of this number, Crieonemoides accounted for 7(0.990Co); Helicotylenchus 544 (76.840Co); Meloidogyne larva 62 (8.760Co); Pratylenchus 19 (2-680Co); Rotylenchus 64 (9.040Co) and Tylenchus 12 (1.690Co). the researcher; considering the negative effect of these on the yield/production of tomatoes, suggests/profers/and also, when transplanting, inter cropping.

Introduction

Nematodes are tiny, thread-like worms measuring 0.0 15 inch to 0.187 inch in length. They are either free living parasitic or saprophytic, identified on the basis of shapes, size and special structures. The females become swollen and flask-shaped as a result of accumulation of eggs with the anus virtually terminal in position, while the males are vermiform (Sherf and Macnah, 1986; Chitwood, 1949; Taylor and Sasser, 1978; Idowu, 1979 and Idowu, 1983)

rnNematodes are known for causing destructive diseases of crops as they have a wide range of feeding habit, constitute about 80% of all multicellular animals, attacking nearly every crop that is grown in the field and as a result crop yields is greatly affected reducing quantity and quality of crops on field, orchard, home garden and green houses (Mai, 1985; Symth, 1994; Sasser, 1952). Among the favoured host in Nigeria as a whole include tomato, yam, tobacco, papaw, citrus and sweet potato (Sasser, 1954).
rn
rnTomato (Lycopersicum esculentum) belongs to the family Solanaceae and subilass polypetalae of the dicotyledenous group of plants. Tomato is a slight modification of tomato the name used by the Indians of Mexico, who have grown the plant for food since prehistoric times. Other names reported by early European explorers were tomato, tumatle and tomatas, probably variants of Indian words (Wener, 2004).
