MANEJO DE Heterodera glycines NA CULTURA DA SOJA UTILIZANDO PRODUTOS BIOLÓGICOS

Abstract

Soybean (Glycine max) is one of Brazil’s most important agricultural crops, playing a key economic and strategic role in agribusiness. However, its productivity is continually threatened by plant-parasitic nematodes, especially Heterodera glycines, which cause significant yield losses. Given the limitations of chemical control and the growing demand for sustainable practices, bio-input has emerged as a viable alternative for managing this pathogen. This study reviews biological control strategies against H. glycines using beneficial microorganisms such as fungi and bacteria. The findings show that agents such as Purpureocillium lilacinum, Pochonia chlamydosporia, Bacillus spp., and Trichoderma spp. are effective in suppressing nematode populations, promoting plant growth, and improving soil health. The integration of these bio-inputs with other practices, including the use of resistant cultivars and crop rotation, proves essential for the success of integrated pest management in soybean cultivation.
