Qualidade de sementes de feijão-caupi tratadas com produtos químicos e armazenadas em condições controladas e não controladas de temperatura e umidade Quality of cowpea seeds treated with chemicals and stored in controlled and uncontrolled temperature and humidity conditions

The cowpea is a Fabaceae originated in Africa cultivated in the northern and northeastern of Brazil, where stands out as the main source of protein for the population. For the establishment of culture, seeds are treated to control and prevent pest attacks and diseases, can also attach nutrients to the seeds which will be available for plant development. The objective of the research was to evaluate the performance of cowpea seeds treated with chemical products and stored in controlled and uncontrolled temperature and humidity conditions. The following seeds treatments were applied: control (no treatment); micronutrient Comol 118, insecticide thiamethoxam, ?pronil and pyraclostrobin+thiophanate-methyl and imidacloprid+thiodicarb were then stored in a cold environment and natural. The assessment of physiological seed quality was made initially and every 45 days through the germination and vigor.
