Calculation of risk indices for diseases and pests based on weather data
1994
Secher, B.J.M.
In order to improve existing DSS on Crop Protection a project has been initiated to develop risk indices for major pests and diseases in cereals based on detailed weather information from an agrometeorological network or a locally mounted measuring unit. The initial risk index for yellow rust on winter wheat is based on a sporulation probability and a following probability of infection. A preliminary evaluation has shown that the index can define years with a high or low level of the disease but only when used together with field observations on amount of inoculum present. The index will be improved by adjusting the parameters and integrating the number of possible disease cycles in the season
