Control of Digitaria insularis resistant to glyphosate using a combination of herbicides in coffee farms. Coffee Science, Lavras, v. 16, p. 1-5, 2021.1984-3909https://doi.org/10.25186/.v16i.1876http://www.sbicafe.ufv.br/handle/123456789/12791Coffee has a significant economic, social, and cultural impact on Brazilian society, generating jobs for thousands of Brazilians. Good management practices such as weed control have direct and indirect benefits on coffee yield and quality. Currently, there is an increase in the infestation rate of Digitaria insularis in coffee plantations due to chemical resistance to glyphosate. In the literature, the study of the combination of glyphosate with different herbicides has been investigated, aiming at improving the efficiency of the control of D. insularis. The objective of this work was to evaluate the efficiency of control of the D. insularis in a coffee farm using a combination of glyphosate with clethodim and phenoxaprope-p-ethyl. Trials were conducted in a commercial coffee farm in southern Minas Gerais in a field with a two-year-old cultivar IAC Catuaí 144. The experiment was conducted under a completely randomized design with five treatments and four replications, totaling 20 experimental plots. Thirty and ninety days after application, the number of plant were counted. The results show that the use of glyphosate alone was not efficient to control of D. insularis. The results show that the herbicide mixtures were efficient in the control.pdfenOpen AccessChemical controlMixturesActive ingredientsCoffea arabicaHerbaceousWeedsCafeicultura::Pragas, doenças e plantas daninhasArtigo
