Summary: 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.
