Flutuação populacional e efeito da distância e profundidade sobre nematoides em bananeira no norte de Minas Gerais

Abstract

The distribution of Meloidogyne javanica and Helicotylenchus multicinctus populations was assessed in naturally infested area cultivated with banana cv. Prata-Anã irrigated by microaspersion. Soil samples were taken at distances of 20, 40, 80 and 120 cm from the pseudostem and from 20, 40 and 60 cm of depth, bimonthly, per two years. The population densities of M. javanica and H. multicinctus were greater at distances of 20 and 40 cm from the pseudostem, respectively. The population of both species M. javanica and H. multicinctus was high in December 2002 and decreased until November 2004 when it became stable.
