Extratos aquosos de Azadirachta indica e de Annona spp. no controle de nematoides da bananeira

ABSTRACT: The banana tree (Musa spp.) is the second most produced fruit crop and first consumed in Brazil. Among constraints affecting causing production losses are plant-parasitic nematodes. objective of present work was to evaluate effect neem (Azadirachta indica), Annona muricata (soursop) A. squamosa (sugar apple) aqueous leaf extracts treatment plantlets cv. Comprida, naturally infected by nematodes, under greenhouse conditions. Four concentrations (0.5, 1.0, 1.5 2%) were tested addition controls (Carbofuran water); immersion period 60 minutes. A completely randomized design a factorial scheme (3x4) with eight replications used. experiment evaluated three months after treatments applied, observing sprouting percentage seedlings, nematode’s population soil, rhizome roots, reproduction factor. There significant interaction between for final nematodes root, total population. reduction root factor observed treated neem, soursop sugar apple when compared negative control (water). KEYWORDS: Musa spp., Alternative control, Pratylenchus spp.
