Effect of three post-emergence herbicides on coffee growth and weed control
Glyphosate, paraquat and dalapon were evaluated as post-emergence herbicides for weed control in young sun-grown coffee trees. The experiment was conducted in lat. 18{eth} N. and long. 66{eth}48' W., and at an elevation of 588 m. Glyphosate killed the weeds more effectively than paraquat and dalapon. Excellent weed control was observed at 4.70, 7.05 and 9.40 l/ha, and very good control when applied at 2.35 l/ha. Coffee growth was temporarily retarded only when the glyphosate solution drifted to the tree. Dalapon did not provide control against broadleaf weeds
