Identification of plant parasitic nematodes associated with the bean crop (Phaseolus vulgaris L.) in northwestern Argentina

Abstract

Fifty samples of soil taken in bean fields from eighteen circunscriptions of the Tucuman province (Argentina) were analized in order to recognize the species of nematodes present in the crop.

The following genera were found: Meloidogyne; Heterodera; Pratylenchus; Helicotylenchus; Hoplolaimus; Paratylenchus; Tylenchorhynchus; Criconemoides; Xiphinema and Trichodorus.

The root-knot nematodes: Meloidogyne (M. javanica; M. incognita; M. arenaria y M. decalineata) are one of the most serious problems for bean production in northwestern Argentina. Damage, importance and dispersion are mentioned.
