What is the reason to make economic calculations of proposed preventive and control strategies beforehand?
For implementation of new strategies to control D. suzukii or new IPM strategies, the economic consequences for growers should be clear. The new strategies must lead to economic sustainable solutions for the grower, if not, growers will not use them. If the critical factors for the implementation on costs and labour are calculated at the beginning of the project, these can be used as research guide during the development of the new strategies. With this, the possibility of real implementation increases.
Why should the economic calculations be made again at the end of the project?
At the beginning of the project, not all data needed for the calculations are known, as the strategies are still in development. Therefore, calculations are made based on available data, including estimations. At the end of the project more real data such as costs, labour need and influences on production, are available, based on trials and further research. With these data the economic calculations can be made more accurate and can be used for dissemination.
