Abstract

Wheat (Triticum aestivum L.) is a cereal with great economic importance and yield capacity. However, it can be attacked by various diseases, which require the use of fungicides during crop development. Thus, this study aimed to evaluate the physiological quality of wheat seeds when treated with fungicides concentrations during crop development. Plants of Mirante variety were cropped with foliar application of fungicides with active ingredients strobilurin and triazole plus foliar adjuvant. After harvesting, the seeds moisture content, germination percentage, accelerated aging, controlled deterioration, cold test, sand emergence, electrical conductivity and aflatoxins presence were evaluated. The obtained results showed that physiological quality and aflatoxin presence in wheat seeds were not influenced when the studied fungicides were used. The seeds showed high seedling germination index, even when submitted to stressful conditions.
