When using RIMPRO or other forecasting systems that do not require you to enter either trap data or a biofix derived from your own data be aware that these systems use degree day calculations based on accumulations from a calendar date to forecast the biofix. This is not necessarily a problem if you understand that it is predicting biofix and that you can ground truth that with trapping data.
Just relying on the predicted biofix means you may be using more sprays than you need. These systems may not forecast the 2nd cohort of codling moth unless they have been programmed to measure daylength or latitude. The forecasts for scab activity have the same limitations and benefits in that they do not take account of pest population size or disease inoculum but they are general models for when activity may occur.
