Resulting from a spontaneous mutation of conventional corn, sweet corn has high productivity potential in Brazil, being considered a profitable alternative for producers, and putting it on the rise. However, the scarcity of technical information reduces this advance. In order to analyze the viability of the seed, the laboratory germination test is used to compare the quality between lots and to estimate their performance for sowing in the field. Susceptible to attack by fungi and insects, due to its composition and morphological characteristics, the treatment of sweet corn seeds with chemicals is a viable option to reduce possible quality losses. In this way, the incidence of phytopathogenic fungi was analyzed, as well as their reduction due to the use of fungicides in the TS. However, for the germination test, one can find antagonism of the value obtained for treated seeds, related to the performance of these seeds in the field. In order to elucidate and correct these errors, a study of the conditions that provided them was carried out and solutions to the problem were defined, adapting to the methodologies used in the germination tests.
