Resumo
Espírito Santo is the highlight among the Brazilian states producing conilon coffee (Coffea canephora), with about 80% of national production. The occurrence of spontaneous plants and/or weeds in agricultural crops is notorious. Among the herbicides used to control these plants, glyphosate is the active ingredient, one of the main non-selective herbicides used to control weeds in coffee plants. The objective of the first chapter was to use the bibliometric review as it is a planned method, which makes it possible to collect, select and critically analyze the studies. A search was carried out on the Scopus platform with the terms in English: “control*”, weeds*, drift* and glyphosate*. From these records can be obtained between 1992 and 2022, they were selected and analyzed by the VOSviewer software. Highlighting Brazil, the country that publishes the most regarding the researched terms, this is due to the fact of its great worldwide representation in coffee production. The objective of the second chapter was to evaluate which tip and which application rate are favorable for the parameters, density, coverage, DMV, and droplet deposition. The experiment was carried out at the Experimental Farm of the Centro Universitário Norte do Espírito Santo, at the Federal University of Espírito Santo, in a randomized block design with treatments distributed in a 3 x 3 factorial scheme, with three spray nozzles and three application rates, four replicates per treatment. The BD11002 tip, when used at any application rate, resulted in very thick drops, not being a good option, as it had a high flow rate of the syrup. The JDF06 tip, regardless of the application rate, provided better distribution of the product on the target, therefore, being the best option for application
