Research Papers: Effect of Time Lapse on Pathogenicity and Population Dynamics of Pratylenchus alleni and P. scribneri in Soybeans.

Abstract

In a 10-month greenhouse study of population dynamics, numbers of Pratylenchus alleni Ferris and P. scribneri Steiner increased rapidly during the first four months after inoculation in Clark 63 soybeans, reached a "ceiling level", and began to decline. Populations of P. alleni peaked after five months at 178X the inoculum level, while those of P. scribneri peaked after eight months at 188X the initial level.
