Escenarios bioclimáticos de tizón tardío [Phytophthora infestans (Mont.) De Bary] en Ciego de Ávila, Cuba.

Abstract

Constituye un quehacer relevante para la investigación agrícola actual predecir e interpretar la influencia del cambio climático sobre los organismos nocivos de los cultivos y adaptar el manejo fitosanitario. Interpretar los escenarios bioclimáticos de Phytophthora infestans, agente causal del Tizón tardío de la papa en áreas del cultivo en Ciego de Ávila durante el período de noviembre – abril para los años 2025 y 2030 bajo escenarios (SRES) A2 y B2 constituyó el objetivo de este trabajo. En la confección de los escenarios bioclimáticos se emplearon datos diarios de acumulados de precipitación y temperatura media del Modelo Regional PRECIS-CARIBE. Además de los índices biológicos requeridos por el fitopatógeno para desarrollar epifitias considerados en el método de “Umbral de lluvias” recomendado por el Instructivo técnico del cultivo en Cuba. Los resultados coinciden en un ambiente con condiciones meteorológicas no favorables para el desarrollo y la evolución de Tizón tardío tanto en 2025 como en 2030. Específicamente, la poca ocurrencia y al bajo acumulado de las precipitaciones que no superan los niveles que señala la línea de umbral, así como la incidencia de temperaturas medias superiores a 24 °C. Los escenarios bioclimáticos obtenidos de este Oomycetes brindan información para la futura planificación y el manejo fitosanitario del cultivo; selección de insumos y atenciones culturales que propicien la aplicación de una agricultura climáticamente inteligente que contribuya a la producción sostenible del tubérculo.
