Erweiterung des Entscheidungshilfesystems Öko-SIMPHYT zur Reduktion der Kupferapplikationen gegen Phytophthora infestans im ökologischen Kartoffelanbau Organic Eprints
Bruns, C.; Schulz, H.; Tebbe, C.; Racca, P.; Werren, Dagmar; Finckh, Maria R.; Kleinhenz, Benno.
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...
