Resumen
El proyecto de investigación fue desarrollado en Laboratorio Experimental de Campo de Suelos y Aguas (LECASA) ubicado en la Universidad EARTH, Las Mercedes, Guácimo, Limón, Costa Rica, en los meses de julio y agosto del 2017, evaluando el potencial herbicida del agua salina para controlar a Euphorbia thymifolia. Se evaluaron nueve tratamientos de una o doble aplicación de agua salina en diferentes concentraciones con y sin jabón como coadyuvante, con cinco repeticiones. Se evaluó el daño provocado a E. thymifolia a los 1, 3, 5, 7, 14 y 21 días después de la aplicación. Como resultado se obtuvo que dos aplicaciones de las dosis de 100 %, 75 % y 50 % de agua salina con 10 % de jabón como coadyuvante, se logra controlar y causar mortalidad a E. thymifolia. Se concluye el uso de un coadyuvante junto con al agua salina es necesario para control efectivo de esta maleza.

There were developed nine treatments, of one or double application of saline water, in different concentrations with and without soap as a co-adjuvant, with five repetitions. The damage caused to E. thymifolia was evaluated at 1, 3, 5, 7, 14 and 21 days after the application. As a result, it was obtained that two applications of 100 %, 75 % and 50 % rates of saline water with 10 % soap as co-adjuvant, are possible to control and cause mortality to E. thymifolia. It is concluded that the use of a co-adjuvant together with saline water is necessary to control effectively this weed.
