الوصف: Dentre as opções de controle de plantas daninhas em gramados, destaca-se o uso de herbicidas, porém poucas informações existem na literatura sobre a sua seletividade a gramados. Assim, foi desenvolvida a presente pesquisa em casa de vegetação da ESALQ - Piracicaba, com o objetivo de testar a seletividade de herbicidas aplicados em pré-plantio (sulfentrazone a 1,4 kg i.a. ha-1 e oxadiazon a 1,0 kg i.a. ha-1) e em pós-emergência (halosulfuron a 112,5 g i.a. ha-1, 2,4-D a 2,010 kg i.a. ha-1 e MSMA a 2,4 kg i.a. ha-1), em cinco espécies de gramas (família Poaceae): são-carlos (Axonopus affinis), esmeralda (Zoysia japonica), bermuda (Cynodon dactylon), zoysia (Zoysia matrella) e santo-agostinho (Stenotaphrum secundatum). As conclusões gerais deste trabalho de pesquisa foram de que a seletividade de herbicidas aos diversos tipos de grama é função principalmente da espécie de grama e do tipo e da dose do herbicida aplicado. Dentre os herbicidas testados, destacam-se como mais seletivos o halosulfuron na dose de 112,5 g i.a. ha-1 e o 2,4-D na de 2,010 kg i.a. ha-1; as espécies de grama do gênero Zoysia (esmeralda [Z. japonica] e zoysia [Z. matrella]), de maneira geral, são mais tolerantes aos herbicidas testados nesta pesquisa.Among the weed control options, herbicide is certainly one to be considered for weed control in turfgrass; however, little has been published about herbicide selectivity, specially under Brazilian landscape conditions. Therefore, this research was conducted at USP/ESALQ, Piracicaba-SP, Brazil, to evaluate herbicide selectivity to turfgrass of pre-planting application herbicides (sulfentrazone at 1.4 kg a.i.ha-1 and oxadiazon 1.0 kg a.i.ha-1) and post-emergence application herbicides (halosulfuron at 112.5 g a.i.ha-1, 2,4-D at 2.010 kg a.i.ha-1 and MSMA at 2.4 kg a.i.ha-1), in five species of turfgrass: Axonopus affinis Chase, Zoysia japonica, Cynodon dactylon, Zoysia matrella and Stenotaphrum secundatum. It was concluded that herbicide selectivity to the turfgrass species studied is a function of the grass species and herbicide type and rate sprayed. Among the tested herbicides, halosulfuron at 112.5 g a.i.ha-1 and 2,4-D at 2010 g a.i.ha-1 were the most selective ones, and the grass species of the genus Zoysia (Z. aponica and Z. matrella), were, in general, the most tolerant to all the herbicides tested.
