FACTORS INFLUENCING A PETAL-BASED FORECASTING SYSTEM FOR SCLEROTINIA STEM ROT OF CANOLA
… changes in infestation during flowering. Disease incidence was significantly related to canopy density,as indicated by percentage light penetration through the canopy, and increased as light penetration decreased. Higher disease incidence in the denser canopies was attributed to more …

Statistical Modelling of Mosquito Abundance and West Nile Virus Risk with Weather Conditions
… of mosquito vectors of mosquito-borne infectious diseases such as West Nile virus (WNv). Study and prediction of these effects could be used to develop disease forecasting methods. In this dissertation, we analyzed the frequency distribution of mosquito surveillance data and built the statistical …

The Role of Host, Environment, and Fungicide Use Patterns in Algorithms for Improving Control of Sclerotinia Blight of Peanut
An algorithm was developed for assessing disease risk and improving fungicide timing for control of Sclerotinia blight of peanut, caused by Sclerotinia minor. A 5-day index (FDI) of disease risk was calculated daily by multiplying indices of moisture, soil temperature, vine growth and canopy …
