La zona del Caribe costarricense, en especial el cantón de Matina, se caracteriza por la cantidad de plantaciones agrícolas, dentro los cuales destacan los monocultivos de banano (Llaguno et al., 2014). Este desarrollo se ...
Evaluación de efectos tóxicos tempranos tras la exposición de peces (Parachromis dovii) a una mezcla de Clorpirifos y Difenoconazol, a través de la respuesta de una batería de biomarcadores bioquímicos e histopatológicos
(Universidad Nacional, Costa Rica, 2019)
En Costa Rica, la agricultura es una de las actividades económicas más importantes. El clorpirifos (CPF) y el difenoconazol (DFZ) han sido identificados como plaguicidas ampliamente utilizados en los cultivos de banano y ...
