Influence of Temperature and Initial Population Density on Population Development and Pathogenicity of Tylenchorhynchus agri on Trifolium pratense and Poa pratensis

Abstract

At initial densities of 0 to 10,000 Tylenchorhynchus agri Ferris/pot and temperatures ranging from 22-36C, population increase was fastest at lower densities and at the higher temperatures on bluegrass (Poa pratensis L.) and clover (Trifolium pratense L.) Pathogenicity of T. agri was greatest at higher temperatures.
