se desarrolló en 1989 para evaluar el control de la enfermedad con la aplicación de cuatro fungicidas en la variedad Sam' Pride en un invernadero comercial. Dos fungicidas protectores Diclofluanid y Propineb y dos fungicidas sistémicos Penconazol y Triforine se aplicaron semanalmente 8 veces. Un número bajo de lesiones se obtuvo con la
aplicación de los funqicidas protectores, siendo Propineb el fungicida más efectivo. Todos los fungicidas utilizados afectaron la producción de esporas en las lesiones, pero la germinación de las esporas fué más afectada por los fungicidas sistémicos, especialmente con el Triforine. Las observaciones en postcosecha de tallos, hojas y flores no mostraron diferencias significativas entre los tratamientos
utilizados.
Colombia. An experiment was carried out in 1989 to evaluate the control of diseases with the application of four fungicides with the very susceptible variety Sam'Pride in a cornmercial
greenhouse. Two protectant fungicides Dichlofluanid and Propineb an two svstemic fungicides Penconazol and Triforine
were applied weekly eigth times. A lower number of lesions were obtained with the application of the protectant fungicides, being Propineb the most effective. All fungicides
used, affect the production of spores on the lesions, but their germination was more affected by systemic fungicides, especially Triforine. Postharvest observations of stems, leaves and flowers, did not show significant differences between treatments.
