“…Based on data from the Ministry of Agriculture, Livestock and Supply -MAPA (Ministério da Agricultura, Pecuária e Abastecimento, [MAPA] 2020), there are currently 203 products formulated in Brazil based on the 16 different active ingredients recommended for pasture weed control. Brighenti, Calsavara and Varotto (2017), in Rio de Janeiro and Minas Gerais, evaluated the selectivity of the herbicides atrazine + S-metolachlor, atrazine + simazine, ametryn, ethoxysulfuron, S-metolachlor, diuron + hexazinone, sulfentrazone, and imazethapyr and atrazine at doses normally recommended in the package insert during the pre-emergence of elephant grass (P. purpureum). These researchers concluded that the herbicides atrazine + S-metolachlor, atrazine + simazine, ametryn, ethoxysulfuron, S-metolachlor, sulfentrazone, and atrazine did not cause phytotoxicity to elephant grass plants 35 d after treatment (DAT), being selective to the crop.…”
