ABSTRACT - Fumigation is a technique employed to eliminate insect pests in stored seeds by using gas. The aim of the experiment was to evaluate the effect of the gas phosphine on germination and on vigor (accelerated aging and seedling length) of soybean seeds. Soybean seeds of two cultivars with two vigor levels were used. Each treatment was replicated four times and each experimental unit consisted of two kilograms of seeds, which were placed in individual 1 m3 gas-tight capacity chambers with phosphine. The concentrations used were 1.0; 2.0 and 3.0 g PH3.m-3, achieved by applying 3.0; 6.0 and 9.0 g of Fertox® commercial formulation. During seven days, the phosphine gas concentration within each chamber was monitored using the Silochek® gas meter. After this period, the chambers were opened, the seeds were removed and the quality analyses were performed. Throughout the experiment, PH3 concentrations in the chambers remained at the concentrations required for the elimination of all life stages of insect pests of stored seed. Even in the lowest dosage, the gas concentration remained above 400 ppm that is considered the minimum concentration for eliminating insect pests. No detrimental effects were detected on the physiological quality of the fumigated seeds. RESUMO - O expurgo é uma técnica empregada para eliminar pragas infestantes em sementes armazenadas mediante uso de gás. O objetivo do experimento foi avaliar o efeito da fosfina na germinação e no vigor (envelhecimento acelerado e comprimento de plântula) da semente de soja. Foram usadas sementes de soja de duas cultivares com dois níveis de vigor. Cada unidade experimental composta por dois quilogramas de sementes de cada repetição foi colocada em câmaras individuais de expurgo. Foram usadas concentrações de 1,0; 2,0 e 3,0 g de PH3.m-3, conseguidas pela aplicação de 3,0; 6,0 e 9,0 g do produto comercial Fertox®. Diariamente, durante sete dias, foi monitorada a concentração do gás fosfina no interior de cada câmara através do medidor Silochek®. Após este período, as câmaras foram abertas, retiradas as sementes e realizadas as análises de qualidade. As concentrações de fosfina se mantiveram nas concentrações necessárias para a eliminação de todas as fases das pragas de sementes armazenadas. Mesmo a dose mais baixa manteve a concentração superior aos 400 ppm que é a referência técnica de concentração mínima para eliminar os insetos praga. Não foram detectados efeitos adversos dos tratamentos na qualidade fisiológica das sementes de soja.
