Biological control of Meloidogyne javanica in bean plants by Hohenbuehelia spp. and Trichoderma koningiopsis

ABSTRACT Nematode control strategies are limited and alternative is demanded. The main aim was to evaluate potential of Hohenbuehelia spp. (Hohenbuehelia mastrucata, barbatula, bullulifera, portegna, petaloides paraguayensis) Trichoderma koningiopsis against Meloidogyne javanica in bean plants greenhouse. parameters evaluated were the number galls egg masses which three root regions: basal, intermediate tip; nematode reproduction factor; vegetal growth (plants height on V1, V2, V4, R5 stages, length, dry weight aerial part weight); Treatments composed by individual interactions each fungal isolate with 4,000 eggs M. javanica, having a total (bean) partial (bean + nematode) arranged completely randomized design four repetitions. Data tested Scott–Knott (5%). For parameters, there only significance for roots. All species able nematodes.
