| Summary, etc |
La presente investigación se realizó en zonas cafetaleras altamente lluviosas de Guatemala, con el objetivo de evaluar el control económico de malezas mediante el uso de glifosato combinado con aditivos. Se aplicó una metodología experimental de campo, comparando tratamientos con glifosato solo y glifosatos más aditivos, bajo un diseño estadístico adecuado, considerando eficiencia de control, persistencia y costos. Los resultados evidenciaron que la adición de aditivos mejoró la eficacia del herbicida bajo condiciones de alta precipitación, redujo la frecuencia de aplicaciones y disminuyó los costos de manejo, logrando un control eficiente y económicamente viable de las malezas en el cultivo de café. |
