Sumario: | An experiment was carried out at "La Selva"
ICA 's experimental station located in Rionegro (Antioquia) at 2.120 meters above sea level and with
170 C as average temperature. The objectives were to
evaluate the effect of Alternaria dauci and Cercospora carotae on carrot cv "Danvers 126" production as
well as the control obtained by applying different
fungicides every week and every other week. During
the experiment 1.043 mm of rain fell down. The model to relate percentage of diseases and yield was highly significant with a determination coefficient of 927o.
Better control and higher yields were obtained by
applying the products every week. Captafol (1,6 g
of i.a./l of water) produced the best control and the
highest yield. As alternative for control of these fungi
the products Chlorotalonil and Stanium Hidroxide
(1,5 and 0,4 g of i.a./l of water, respectively) were
considered
