The bioactivator are complex organic substances that can alter the growth, capable of acting on the transcription of DNA into the plant, gene expression, cell membrane proteins, metabolic enzymes and mineral nutrition. The insecticide thiamethoxam has demonstrated positive effects as increased expression of vigor and biomass formation, the elevation of photosynthetic rate and the formation of deeper roots. The aim of this study was to evaluate the physiologic performance of tiamethoxan on the oat. Were used oat seeds and product concentrations 0.0, 100, 200, 300, 400ml. to 100 kg of seeds. To evaluate the physiological quality of seeds were carried by germination test, first germination, cold test, seedling length, shtoot and root, tetrazolium test and emergency in the greenhouse. The product tiamethoxan stimulates physiologic performance of oat seeds. The use of the 300 ml of tiametoxam per 100kg, seeds shown to be more efficient to improve the physiological performance of seed oat.
