| description | The late blight of celery disease is caused by the fungus Septoria apiicola; which causes damages on the plant’s foliage affecting its commercial quality up to 70% of its value in absence of control. There are several ways to manage diseases; one is through the use of a chemical control which presents very positive results, however, most of the time this solution is affected by bad practices at application, rain and other adverse conditions raising its cost. In this study were tested the effect and results of two preventive fungicides, copper oxychloride and chlorothalonil, combined with three adjuvants: Mixel® (wetting agent), Figo® (sticker) and Carrier® (carrier). It was used the commercial hybrid of the celery ‘Ferry Ventura’. The study was carried out with two trials during the second semester of 2004 and the first semester of 2005, at Marengo Center located in the municipality of Mosquera, Cundinamarca, in Colombia, (2,556 m above sea level, 645 mm precipitation per year, 14.7ºC annual temperature and 80% relative humidity), using a randomized design of complete blocks with nine treatments and three blocks divided in plots of land of 9.5 m2. The variables measured were: degrees of severity (according to predetermined visual scale), and commercial fresh weight at the time of harvest; additionally an economic analysis was done considering the variable costs, net income and the relation benefit - cost of treatments. In conclusion the best adjuvant for the fungicides was the sticker (Figo) from a biological efficiency point of view; on the other hand and according to the economic evaluation the best treatment was the combination of copper oxychloride with the sticker. The prevented fungicides required adjuvants for best results. |

La septoriosis o tizón tardío del apio es una enfermedad ocasionada por el hongo Septoria apiicola, que provoca daños sobre el follaje de la planta demerita su calidad y valor comercial hasta un 70% en ausencia de control. Existen varios métodos de manejo de enfermedades, de los cuales el control químico presenta los mejores resultados, sin embargo, se ve afectado por condiciones adversas de manejo como malas prácticas de aplicación, lavado por lluvias, altos costos, etc. En este trabajo se evaluó el efecto de tres coadyuvantes “Mixel®” (dispersante), “Figo®” (pegante) y “Carrier®” (portador) en la eficiencia de control de dos fungicidas preventivos oxicloruro de cobre y clorotalonil formulados en polvo mojable sobre la Septoria en el híbrido comercial de apio ‘Ferry Ventura’. El estudio se realizó en dos ensayos durante el segundo semestre del año 2004 y el primero del año 2005 en el Centro Agropecuario Marengo, ubicado en el municipio de Mosquera, Cundinamarca (2.556 msnm, 645 mm precipitación anual, 14,7ºC temperatura promedio anual y 80% humedad relativa); se empleó un diseño de bloques completos al azar con nueve tratamientos y tres repeticiones por tratamiento en parcelas de 9,5 m2. Las variables medidas fueron: grados de severidad (de acuerdo a una escala visual predeterminada) y peso fresco comercial al momento de cosecha; adicionalmente se realizó un análisis económico para estimar los costos variables, ingresos netos y la relación beneficio-costo de los tratamientos. Las aplicaciones se iniciaron con la aparición de las primeras lesiones causadas por la enfermedad. Se concluyó que la mejor propiedad coadyuvante para los dos fungicidas oxicloruro de cobre y clorotalonil fue el pegante y de acuerdo con la evaluación económica el mejor tratamiento fue la combinación de oxicloruro de cobre con el pegante. Los coadyuvantes, independiente del tipo de acción, contribuyen a mejorar la eficiencia del oxicloruro de cobre y el clorotalonil.
