PATHOGENIC POTENTIAL OF PRATYLENCHUS THORNEI ON SOME MEDICINAL AND AROMATIC PLANTS

Abstract

Studies were undertaken to evaluate the pathogenic potential of Pratylenchus thornei on fifteen medicinal and aromatic plants in a glasshouse (25±3 °C) pot experiment. The results indicated that all the tested species inoculated with 5000 nematodes per plant suffered a significant (P =0.01) reduction in plant length and fresh weight as compared to uninoculated controls. Greatest reduction in root length, shoot height and fresh root-shoot weights occurred in Trigonella foenum-graecum and the least in Apium graveolens. None of the plants was resistant to P. thornei.
