INFLUÊNCIA DO TEOR DE UMIDADE E CONTROLE QUÍMICO NA INCIDÊNCIA DE FUNGOS EM GRÃOS DE SORGO

Abstract

The present work sought to evaluate the incidence of pathogenic fungi in sorghum grains harvested at different moisture contents with and without the application of fungicides and to identify the genera of the microorganisms found. The experiment was carried out at the Centro Tecnológico Comigo, CTC, in Rio Verde – GO and the tests were carried out in the Phytopathology and Nematology laboratory of the Instituto Federal Goiano – Campus Rio Verde. Two genera of fungi were identified in sorghum grains: Fusarium spp. and Aspergillus spp. in isolation or simultaneously. The incidence of Fusarium spp. did not differ in relation to the two moisture contents at harvest and fungicide applications. The same happened for Aspergillus spp. when it occurred in isolation. When the fungi identified occurred simultaneously, the use of fungicides was effective. Moisture contents did not influence the incidence of Fusarium spp. and Aspergillus spp. when they occurred synchronously.
