Interrupted Wet Period (IWP) to Forecast the Aerial Alternaria in Potato Crops of A Limia (Spain)

摘要: Potato early blight caused by Alternaria solani generates significant economic losses in crops worldwide. Forecasting the risk of infection on is indispensable for management fungal disease, ensuring maximum benefit but with minimal environmental impact. This work aimed to calculate interrupted wet periods (IWP) according climate conditions A Limia (Northwest Spain) optimize prediction against potatoes. The study was performed during nine crop cycles. relative hourly humidity and concentration environment were taken into account. levels monitored aerobiological techniques using a LANZONI VPPS-2000 volumetric trap. relationships between weather airborne statistically analyzed Spearman correlations. To establish effectiveness wetness periods, first important peak account each cycle (with greater than 70 spores/m3). Considering six system, it possible predict several days advance (between 6 38 days), except 2007 2018. Automated systems initiation potato crop, such as could be an effective basis developing decision support systems. incorporation data calculation improved results this system.
