Chemical control of the fairy ring spot of carnation caused by heterosporium echinulatum

The fairy ring spot caused by Heterosporium echinulatum- is one of the most limiting diseases of miniature carnation inColombia. 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 cornmercialgreenhouse. Two protectant fungicides Dichlofluanid and Propineb an two svstemic fungicides Penconazol and Triforinewere applied weekly eigth times. A lower number of lesions were obtained with the application of the protectant fungicides, being Propineb the most effective. All fungicidesused, 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.
