O trabalho avaliou a interação entre temperaturas do solo (13ºC, 15ºC, 17ºC e 19ºC), profundidades de semeadura (2,5; 5,0 e 7,5 cm) e tratamento de semente com fungicida (captan + tiabendazole) na emergência de plantas de milho. Utilizaram-se sementes do híbrido AS 1565 com 22% de incidência de Fusarium verticillioides e solo de lavoura naturalmente infestado. O ensaio foi conduzido em câmaras climatizadas por 25 dias, com contagem diária da emergência. Houve diferença significativa entre sementes tratadas e não tratadas, sendo que quanto menor a temperatura do solo e maior a profundidade de semeadura, maior a resposta ao tratamento de sementes na emergência de plantas. A estabilidade de emergência ocorreu aos 23, 18, 12 e 12 dias após a semeadura respectivamente para 13ºC, 15ºC, 17ºC e 19ºC, mostrando redução na velocidade de emergência nas temperaturas baixas. In this study the interaction between soil temperatures (13ºC, 15ºC, 17ºC and 19ºC), depths of sowing (2.5, 5.0 and 7.5 cm) and seed treatment with fungicide (captan + thiabendazol) in the emergence of plants maize was evaluate. Seed of hybrid corn AS1565 with 22% of the incidence of Fusarium verticillioides was used and soil naturally infested. The trays were kept in conditioned chambers for 25 days, measured daily the emergence. There was significance difference between treated and untreated seeds. According to lower soil temperature and higher the depth of seedling, was largest the response of the seed treatment in the plants emergence. The emergence of plants was measured daily to obtain the stability, which occurred at 23, 18, 12 and 12 days after seedling at temperatures of 13ºC, 15ºC, 17ºC and 19ºC respectively, showing reduction in the emergence speed at low temperatures
