| description |
The strategy of integrated management of witches'broom and monilia pod rot disease contemplates the employ of two control systems: phytosanitary pruning and systemic fungicides. Since 1983, at the ICA Tulenapa Research Center, located in the Urabá region, was evaluated the technical and economics efficiency of the phytosanitary pruning alone and associate to the aplication of the Triadimefon (1.5 I/ha), Pyracarbolid (2.5 I/ha) and Oxicarboxin (1.5 I/ha) for the control of these diseases. The products were applied during the second semester of each year. The results demostrate that all treatments reduced significantly the incidence of diseases yet to do not exist differences between phytosanitary pruning more fungicides, and phytosanitary pruning alone. In average for all treatments, the percentages of infection by monilia pod rot decreased from 71% to 14 1 7o. At the same time, the broom index passed from 163 to 47 since 1983 to 1986. In all treatments the yield increased significantly, compared with the 1982-1983 period of the same experimental area (250 kg/ha), and with respect to the average of all region, which was 400 kg/ha during 1986. The tminimal production obtained throughout of this experiment was 900 kg/ha. The eco nomical and technical analysis of treatments permit to conclude that the fungicide application is not a recomendabie alternative at level of commercial crops. However, should be continue its study and evaluation with the purpose to define a better system of application, and by this way to improve their expression of control which was found at preliminary works. At level of traditional crops their application would result uneconomic, compared with the phytosanitary pruning actually recommended So, the general conclusion is that the unique efficient and economic alternative for the control of these diseases is the phytosanitary pruning. |

La estrategia de manejo integrado de las enfermedades escoba de bruja y moniliasis contempla la utilización de 2 sistemas de control: la poda fitosanitaria y el empleo de fungicidas sistémicos. El estudio se inició en la finca La Marina, región de Urabá, en 1983, con el propósito de evaluar la eficiencia técnica y económica de la poda fitosanitaria sola y asociada a la aplicación de Triadimefon (1.5 lt/ha), Pyracarbolid (2.5 lt/ha) y Oxicarboxín (1.5 lt/ha) para controlar dichas enfermedades. Los productos se aplicaron durante el segundo semestre de cada año, en 3 ciclos a intervalos de 45 días cada uno. Los resultados demuestran que todos los tratamientos reducen significativamente la incidencia de enfermedades, no hallándose diferencias significativas entre poda fitosanitaria más fungicidas y el testigo poda fitosanitaria sola. En promedio para todos los tratamientos, los porcentajes de infección por monilia disminuyeron de 71 a 14 por ciento, mientras que para escoba el índice bajó de 163 a 47 escobas árbol/año, entre 1983 y 1986. Así mismo, todos los tratamientos aumentaron significativamente los rendimientos, y comparados con el observado para el período 1982-1983 en el mismo lote experimental que fue de 250 kg/ha, y con el promedio para la zona que en 1986 fue de aproximadamente 400 kg/ha, la mínima producción obtenida fue de 900 kg/ha. El análisis técnico y económico de los tratamientos permite establecer que la aplicación de fungicidas no constituye, por ahora, una alternativa de control recomendable para cultivos comerciales, por lo cual debe continuarse su estudio y evaluación, buscando alternativas de aplicación que permitan una mejor expresión de los buenos resultados obtenidos en pruebas preliminares. Para el agricultor tradicional su aplicación resultará antieconómica frente a la poda fitosanitaria recomendada. Se concluyó que la alternativa eficiente y económica para controlar estas enfermedades continúa siendo la remoción periódica del material enfermo.
