dc.descriptionSoybean (Glycine max (L.) Merrill) is one of the most cultivated in Brazil and has lost productivity due to the attack of disease pests. Thus, it is necessary to develop new technologies capable of reducing damages caused by such biological agents. The aim of this work was to evaluate whether the chemical management of ‘eyespot’ and the induction of resistance through the use of phosphites and acibenzolar-s-methyl (ASM), in association with commercial fungicides, affect the quality of soybean seeds. The study was conducted in the field, during two consecutive harvests in Dois Vizinhos, Paraná, Brazil, and a randomized blocks experimental designs was used. The response-variables evaluated were yield components, disease severity through specific diagrammatic scales, and seed quality attributes. The use of phosphite and ASM, with and without the combination of fungicides Glifosato, Azoxistrobina + Benzovindiflupir, Azoxistrobina + Ciproconazol and Picoxistrobina + Ciproconazol did not reduce the severity of the mildew and asian soybean rust. The use of combinations of different fungicides was sufficient to mitigate the severity effects of the mildew and asian rust on soybean crop.
