Abstract: The treatment of soybean seeds with chemical products to control pests may impair seed quality and the establishment of the rizobium-plant symbiosis. The aim of this work was to evaluate the performance of soybean seeds treated with insecticides and film coating, as well as the nodulation and plant growth. Soybean seeds were treated with insecticides and polymer in a 6x2 factorial scheme. The insecticides used in the treatments were carbosulfan, clotianidina, fipronil, imidacloprid, tiametoxan and a control without insecticides. Insecticides were applied with and without the polymer, as well as the control. Seeds were evaluated by the germination test, cold test and seedling emergence. In addition, they were inoculated with the strains BR86 and BR96, separately, and sowed in Leonard pots. During the flowering, the plants were evaluated using the number and dry matter of nodules and of the aerial part. The insecticide treatments can reduce the physiological potential of soybean seeds. The reduction in growth and nodulation of soybean plants caused by insecticide treatments depended on the strain used for inoculation. The film coating can interfere with insecticide phytotoxicity, but does not affect the physiological quality of seeds, nodulation and growth of soybean plants.
