Abstract: Resumo -O feijão-caupi é cultivado principalmente por agricultores familiares, com adoção de baixo nível tecnológico, onde o manejo de plantas daninhas é realizado com capinas, sendo cansativa e com baixo rendimento operacional. O objetivo deste trabalho foi avaliar a seletividade de herbicidas e a eficácia de controle de plantas daninhas na cultura do feijão-caupi, variedade BRS Guariba. O experimento foi conduzido à campo com aplicação dos herbicidas (g i.a. ha -1 ) sulfentrazone (500) e oxadiazon (600), em … Show more

“…This demonstrates that black-bean IPR Tuiuiú cultivars present selectivity to the fluazifop-p-butyl + fomesafen mixture. Different results were obtained by Fontes et al (2013) who, when applying the same herbicide mixture, found a 31% phytotoxicity at 28 DAT in cowpea plants; this was credited to fomesafen, since the isolated application of fluazifop-p-butylpractically did not affect the plants of culture. (1) Days after the application of treatments; (2) Means followed by the same letters, within each dose, in the column do not differ among themselves by Tukey's test at 5% probability.…”

“…Weed interference during the bean cycle can significantly reduce grain yield. These variations may also occur according to cultivars, weed species, place where the experiment is conducted, adopted management adopted, among other factors (Teixeira et al, 2009;Fontes et al, 2013). According to Borchartt et al (2011), the critical period of interference prevention in beans is from 4 to 18 days after the emergence of the crop, so that there is no negative effect of weed competition on grain yield.…”

“…Porém, para o feijão-caupi, ainda há escassez de informações sobre a seletividade dos herbicidas à cultura, sendo ainda muito comum a utilização de controle com capinas, com baixo rendimento operacional, além do controle cultural FONTES et al, 2013).…”
