Resumo:  An improved Decisions Support System (DSS) for the control of Phytopththora infestans in organic potatoes was developed in the frame of the CoFree Project. This work included as primary steps the development of an ontogenetic model (Simonto) based on the BBCH scale of potatoes, and its validation. Additionally, the soil mineral nitrogen dynamics in organic potatoes and nitrogen contents of tuber and leaves were modelled and integrated in the existing DSS Öko-SIMPHYT (www.isip.de). The DSS comprises a correction tool at BBCH 60 for the user to improve the quality of the prediction of potato growth and a termination of copper spraying when potential yield of 90 % is reached. This development was based on intensive data mining in existing data sets from previous projects such as the EU project Blight MOP or other mainly nationally funded projects from Germany. The trials were run from 2012 to 2015; varieties with different maturity were included, different nutrition levels and a huge number of sequential harvests were performed to improve the DSS. The data were intensively validated and finally the new models were implemented in a website of ISIP.
