Abstract

Considering the climate and soil, as well as the results achieved by breeding, different regions show a high potential for wheat and barley production. The insecticide thiamethoxan has shown positive effects on increasing the expression of vigor and biomass formation, the elevation of photosynthetic rate and increase the formation of deeper roots. The aim of this study was to evaluate the thiamethoxan influence in the physiological performance of wheat and barley seeds. It was used seeds of two wheat and barley cultivars, and product concentrations of 0.0, 150, 300, 450, 600 ml of thiamethoxan to 100 kg of seeds. To evaluate the physiological quality of seeds, it was conducted the tests of germination, first count, cold, lengths of seedlings, shoots and roots and emergence in field. The product tiamethoxan stimulates the physiological performance of wheat and barley seeds, with varying intensity according to cultivar. Doses of 300 to 400 ml of product per 100kg of seeds were more effective in promoting the expression of the physiological performance of the wheat and barley seeds.
