    The present research work was conducted in the community of El Santuario, located in the Quero canton, Province of Tungurahua, the main objective of this research was to evaluate the efficiency of two fungicides for the management of early blight (C. carotae Pass.) in the carrot crop (D. carota L.). The response variables were percent fungus incidence, percent fungus severity, plant height, root diameter, root length, root weight and yield. Two commercial products, Amistar top and Daconil 720 SC, were used, with an absolute control (no application). The methodology was experimental, a completely randomized block design (D.C.A) was used, with a total of seven treatments and three replications, the hypothesis test was carried out using the Tukey 5% test and for the yield variable the Duncan 5% test was used. Data were taken from 10 plants at random for each treatment. The results obtained confirmed that there were statistical differences in each of the treatments, highlighting the product Daconil 720 SC at a dose of 3.5 ml/l with a lower percentage of infection of Cercospora carotae Pass with an average of 41.33%, severity of the fungus with an average of 3.20%;The plant height was greater with an average of 13.93 cm, carrots of greater weight with a plot average of 244.72 g, average diameter of 4.13 cm, root length with an average of 12.88 cm and with an average yield of 6.12 Tn/ha when this agrochemical was applied.
