ABSTRACT:     The use of herbicides with extended residual periods enables a longer time of weed control, although it may cause toxicity in more sensitive crops after application. The aim of our study was to evaluate the residual effect of tembotrione in soil with distinct textures and humidity. In the first experiment, two bioassays were carried out in one clay-textured Oxisol, with different relative humidities - irrigated and with water deficit. In the second experiment, two bioassays were carried out in a medium-textured and in a clay-textured Oxisol, in different relative humidities. The residual tembotrione effect in soils with water deficit was up to 300 days after application, independently from soil texture. In humid soils, however, the period of this effect is reduced to 200 days long.

RESUMO:   O uso de herbicidas com longo efeito residual possibilita o controle das plantas daninhas por um período de tempo maior, mas podem proporcionar toxicidade em culturas sensíveis plantadas após sua utilização. O objetivo desta pesquisa foi avaliar o efeito residual do tembotrione no solo de textura e umidade contrastantes. No primeiro experimento, foram conduzidos dois bioensaios em Latossolo Vermelho-Amarelo de textura argilosa, com umidade contrastantes - irrigado e com déficit hídrico; no segundo experimento, dois bioensaios em Latossolo Vermelho-Amarelo de textura média e argilosa, ambos com umidades contrastantes. O efeito residual do tembotrione em solos com déficit hídrico é de até 300 dias da aplicação, independente da textura do solo. Entretanto, esse efeito é reduzido para 200 dias em solos úmidos.
