Reação de cultivares de soja aos nematoides das galhas

Abstract

O presente trabalho objetivou avaliar o potencial de reação de 35 cultivares de soja ao parasitismo de Meloidogyne javanica e M. incognita. Os cultivares foram inoculados com 2.000 ovos/juvenis das espécies dos respectivos nematoides na superfície do solo de cada tratamento. O delineamento experimental foi inteiramente casualizado, com cinco repetições para cada tratamento. Aos sessenta dias após inoculação, foram quantificadas as ações parasitárias nos sistemas radiculares, bem como estimado o fator de reprodução (FR) e as principais características agronômicas desses cultivares. Todos os cultivares foram parasitados pelos nematoides, com fator de reprodução (FR) variando entre 0,06 a 0,24 e 0,02 a 0,84 para M. incognita e M. javanica, respectivamente, indicando que os cultivares se comportaram como resistentes, com FR < 1. Os parâmetros agronômicos, mesmo assim, foram afetados pela ação parasitária dos fitonematoides. Contudo, os cultivares P98Y70, 99R03 e FTS 4188 se mostraram mais eficientes.
