Soybean rust (P. pachyrhizi) has reduced the Brazilian soybean production throughout four growing seasons. The fungus can be efficiently controlled by fungicides sprayed at the right timing. Some areas have required two or more sprays, others only one. A system to map risk of plant disease was developed using series of hourly meteorological data, collected over five years. It aimed to identify favorable regions for infection. The system used a network with almost 40 meteorological stations, distributed in the State. Humidity and temperature were extrapolated from these stations to 2838 points using a correlation with altitude. These were the input variables for the infection model. System validation used severity and meteorological data collected during 2003/2004 and 2004/2005 growing seasons. The maps generated by the system indicated that the probability of infection is lower on the west and northwest regions of Parana State. Central/south region presented a higher probability of infection. Other regions had intermediate levels. Soybean rust severity assessed in experiments in different regions agreed with maps generated by the system. The only exception was the central/south region where the probability of infection was higher than the observed disease severity. The system allowed to optimize efforts to control epidemics of soybean rust. |
