DIAGNOSE E ESTRATÉGIAS DE CONTROLE DE NEMATOIDES FITOPATOGÊNICOS NA CULTURA DA CANA-DE- AÇÚCAR NO SUL DO ESTADO DE GOIÁS

Abstract

Sugarcane is one of the most important and widely cultivated crops worldwide due to its relevance in the production of sugar, ethanol, and other products. Beyond its economic value, it also plays a significant social and environmental role. Plant-parasitic nematodes are among the main threats to achieving high productivity and quality in sugarcane. Their control is challenging, as no method is fully effective and sustainable. Therefore, this study aimed to survey the incidence of nematodes and evaluate the efficiency of control strategies in sugarcane cultivated at IF Goiano – Campus Morrinhos. Field trials were conducted with four treatments and four replications, using classical extraction methods for nematodes in soil and roots. Results revealed that Meloidogyne spp. and Helicotylenchus dihystera were the most prevalent and damaging genera, causing root deformities and necrosis that compromised plant development. Treatments involving biological agents and organic matter incorporation significantly reduced nematode populations, achieving results close to those obtained with chemical nematicides. It is concluded that integrated management, combined with accurate diagnosis, is essential to minimize productivity losses, extend the longevity of sugarcane fields, and ensure the sustainability of the production system.
