Abstract


Soil and Root samples were collected from 76 fields cultivated with corn from 7 regions in Syria. The results indicated that 16 species of free-living nematodes and 15 plant-parasitic genera were found at different levels, varying from 1 to 36%. The two genera of plant-parasitic nematodes,Pratylenchus sp. AndDitylenchus sp. were commonly recovered from Corn plants. The frequency distribution of these two genera was 66% in soil and 44% in roots, 51% in soil and 79% in roots, respectively. Three species of lesion nematodes:P. brachyurus, P. penetrans andP. zeae were identified
