A B S T R A C TTo increase the efficiency in the control of weeds, it is common the use of a mixture of the herbicides glyphosate and 2,4-D in the desiccation. This paper aimed to evaluate the residual effect of these two herbicides on the development of maize plants, in soils of different textures. The experiment was conducted in a greenhouse, in 2015, in a completely randomized design in a 2 x 2 x 7 factorial scheme, corresponding to two soils (Red Yellow Latosol and Quartzarenic Neosol), two herbicide application times (5 and 10 days before maize sowing) and seven doses of herbicides (recommended dose of glyphosate, recommended dose of 2,4-D; mixing the recommended doses of glyphosate and 2,4-D; two, ten and fifty times the recommended doses in admixture; and one control), with 4 replicates. After emergence of maize plants, the following variables were evaluated: phytotoxicity, plant height, chlorophyll a and chlorophyll b, shoot fresh and dry matter and root dry matter. In general, there was lower residual effect on the Red Yellow Latosol at all the doses of the herbicides and in the interval of 10 days between the desiccation and sowing.Efeito residual da mistura glifosato e 2,4-D em milho "safrinha" em solos de diferentes texturas R E S U M O Para aumentar a eficiência no controle de plantas daninhas é comum o uso em dessecação da mistura dos herbicidas glifosato e 2,4-D. Objetivou-se, neste trabalho, avaliar o efeito residual da aplicação desses dois herbicidas sobre o desenvolvimento de plantas de milho em solos de diferentes texturas. O experimento foi conduzido em casa de vegetação, no ano de 2015, em delineamento inteiramente casualizado, no esquema fatorial 2 x 2 x 7, sendo dois solos (Latossolo Vermelho Amarelo e Neossolo Quartzarênico), duas épocas de aplicação dos herbicidas (5 e 10 dias antes da semeadura do milho) e sete doses dos herbicidas (dose recomendada de glifosato; dose recomendada de 2,4-D; mistura das doses recomendadas de glifosato e 2,4-D; duas, dez e cinquenta vezes as doses recomendadas em mistura e uma testemunha), com quatro repetições. Após a emergência das plantas de milho foram avaliados os seguintes parâmetros: fitotoxicidade, altura de plantas, clorofilas a e b, massa fresca e seca da parte aérea e massa seca da raiz. Em geral, ocorreu menor efeito residual no Latossolo Vermelho Amarelo em todas as doses dos herbicidas e no intervalo de 10 dias entre a aplicação e a semeadura.
