Rose Mildew - Decision Support Tool (DST)

As part of project HNS 173, a prediction model for rose downy mildew, incorporated with the rose powdery mildew project (HNS 165), has been developed as a stand-alone system which can use weather data files generated by common data loggers. After evaluations in 2010 and 2011, the powdery mildew component of the model has already demonstrated that a considerable reduction in fungicide input (> 25%) may be achieved with use of the model predictions which is both cost-effective and relevant for the Sustainable Use Directive. The addition of the rose downy mildew software has extended the potential of this decision making support and importantly, the tool allows the growers to save spraying time and improve the precision and timing of application.

CP 127 Compendium of pest forecasting models

This project (CP 127) was commissioned to take previous forecasting models built using software no longer in use and have them reproduced in more 'simple' compatible formats. For more information on these models and the project's objectives click here. The models have now been rebuilt in Excel and you can now access models for: Cabbage root fly, Carrot Fy, Pollen beetle, Large Narcissus fly, Day-degree models for aphids, Early emerging flies, Overwinter as pupae, Late- emerging flies and Overwinter as larvae. The models are currently supported by the University of Warwick here:
