Resumo: Management measures should be tested to increase the rice productivity, a staple foodthat is in increasing demand. The aim ofthis study was to evaluate the efficacy ofdifferent doses ofa plant growth regulator, ethyl-trinexapac, combined with the application of the fungicidesepoxiconazole + pyraclostrobin in reducing the height of rice plants to avoid lodging and increaserice yield. The experiment was conducted in a dystrophic Oxisol soil during two harvests(2010/2011 and 2011/2012). The study was arranged in a randomized block design, in a 4 × 2factorial scheme, with four replications. The factors considered were four doses oftrinexapac- ethyl(0, 25, 50, and 75 g ha-1active ingredient (a.i.)), with or without application offungicide (137.25 gha-1a.i.). The growth regulator caused a reduction in plant height in both harvests and affected thenumber of panicles per square meter in the second harvest. The fungicide had no effect on theproductivity and yield components ofthe crop

O objetivo deste estudo foi avaliar a eficácia de diferentes doses de um regulador de crescimento de plantas, etil-trinexapac, combinado com aplicação do fungicida, epoxiconazol+ piraclostrobina, na redução da altura das plantas de arroz,para evitar o acamamento e aumentar o rendimento do arroz. O experimento foi conduzido em Latossolo Vermelho distrófico durante duas colheitas (2010/2011 e 2011/2012). O delineamento foi em blocos casualizados, em esquema fatorial4 × 2, com quatro repetições. Os fatores considerados foram quatro doses de etil-trinexapac (0, 25, 50 e 75 gha-1de ingrediente ativo (a.i.)), com ou sem aplicação de fungicida (137,25 g ha-1a.i.). O regulador de crescimento causou redução na altura das plantas nas duas safras e afetou o número de panículas por metro quadrado no segundo ano de cultivo.
