In a study of the distribution of Pratylenchus alleni and P. scribneri within Clark 63 soybean roots from nematode-infested soil, populations of both nematode species were most abundant in the first 10-15 cm of the root zone, 30 days after planting. There was a distinct decrease in nematode population density in both species with depth of the taproot. Fifty percent of the total P. alleni population in lateral roots was located in the first 5 cm from the taproot, whereas only 26% of P. scribneri population occurred in this region.
