Efecto de fertilizantes foliares y aceite mineral en el manejo integrado del virus de la mancha anillada del papayo (PRSV-P) en el Tulumayo. por Mansilla Córdova, Pedro Javier

“…No se encontraron diferencias estadísticas significativas entre tratamientos para el ABCPE (área bajo la curva de progreso de la enfermedad), pero el tratamiento T s (Quimifol Ca) presentó el menor valor de ABCPE con 8.51, seguido del trátamiento T1 (Triona) con 9.97, mientras que el tratamiento T3 (Promet Cu+ Triona), presentó la mayor ABCPE (14.65), así como las menores tasas de crecimiento y producción, todo lo cual se debería a la reacción fitotóxica producida por la incompatibilidad del Promet Cu y el aceite Triona, que posiblemente debilitó las plantas, aunado a su disposición en el campo, coincidente con la zona de mayor presión de la enfermedad. …”
