Tratamento químico de sementes de soja e qualidade fisiológica no armazenamento

Abstract

The soybean seeds treatments besides offering protection to seeds, contribute to good early development of crop. This research evaluated the interference of the treatments composition as well as evaluate the influence of these treatments in physiological quality of soybean seeds, some days after treatment. For this were used two seeds lots of cultivar AMS Tibagi RR, and each batch performed the treatment with different compositions (Metalaxil + Fludioxonil + Tiametoxan + CoMo; Carbendazin + Tiram + Imidacloprid + Tiodicarbe + CoMo). For each batch a sample was left without treatment. The evaluations carried out two different times were: Germination test; mechanic damage; deterioration by moisture; vigor and viability by tetrazolium test, it was also carried out a field emergence test. The compositions of the used not caused negative effects in physiological quality of soybean seeds, during the storage period after treated.
