Avaliação de nova tecnologia de uso foliar na qualidade pós-colheita de grãos de soja

Abstract

The control of diseases in the field is fundamental, in order to guarantee high productivity and grain production, with good physical, physiological and sanitary quality. Thus, the effect of new technology was evaluated in an isolated and combined manner with fungicide, in the post harvest quality of soybean grains, in a commercial area in Sinop, MT. The moisture content (%w.b.); mass of 1000 grains (g), real density (kg m-3 ), bulk density (kg m-3 ), and the sanitary quality of the grains through the detection of associated fungi. Data were submitted to analysis of variance and the means to the Scott-Knott test, 5% probability. There was no significant difference in real density. Application of the Test Product isolated or associated with fungicide contributes to increase the bulk density of soybeans; and when associated with the fungicide yields greater values of a thousand grain mass. The Isolated Test Product reduces incidence of Fusarium sp. and Aspergillus sp. and; when associated with fungicide reduces the incidence of Phomopsis sp. in soy beans. It is concluded, therefore, that this new technology will contribute to the physical and sanitary quality of soybeans, in post-harvest.
