Experience
We have long history of collaboration with researchers in many countries and of establishing working prototypes for IWM. The examples below are based on our employment at Aarhus University (3rd generation DSS'es) and therefore are less sofisticated than our current 4th generation DSS, IPMwise.
Studies on other older DSS prototypes includes activities in the EU project ENDURE (2007-2009), where we contributed to analyze 70 European DSS for IPM, of which 9 included DSS on IWM. (Rydahl, 2008). As explained in detail below, several international projects have already been executed in the field of DSS in IWM.
IPM Consult is a subcontractor to AU-AGRO in order to keep all the DSS versions running and updated as required by sponsors.
Watch a video presentation of our previous DSS work at Aarhus University.
Norway
Design of DSS was initiated in 2003, and an official version was released in 2005.
Results from field validation trials show that sufficiently robust weed management was achieved and a potential of ~40% reduction of herbicide input as compared to local standards was demonstrated (Ref.).
It runs only in Norwegian language, try it here: VIPS-ugras
Spain
The first DSS prototypes for winter wheat were designed in 2009. Results from field validation trials show that sufficiently robust weed management was achieved and a potential of ~40% reduction of herbicide input as compared to local standards was demonstrated (Montull et al.)
It runs in Spanish and English, but is not available to the public.
Germany, Italy and Slovenia
In the EU project ‘PURE’ (2010-2014), sponsored by EU Framework 7 programme, DSS prototypes were designed for maize, and 2 alternative principles for determination of needs for control were integrated:
• ‘WPT’ (=Weed Potential Treat), which was originally designed by INRA in France
• ‘ET’ (=Efficacy Target), which was originally designed by AU-AGRO in Denmark
Results from field validation trials show that sufficiently robust weed management was achieved and a potential of ~xx% reduction of herbicide input as compared to local standards was demonstrated (Ref.)
It runs in English, but is not available to the public.
Germany, Poland and Denmark
In the EU, project, DSSHerbicide, sponsored by EU South-Baltic, DSS prototypes were designed and field validated for wither wheat, and 2 alternative principles for optimization of herbicide use were integrated:
• optimization of single herbicides and tank-mixtures to meet efficacy targets determined by experts
• optimization of economic net return by use of the Roger Cousens yield-loss function.
Results from field validation trials show that sufficiently robust weed management was achieved and a potential of ~xx% reduction of herbicide input as compared to local standards was demonstrated (Sønderskov et al. 2015).
The prototypes run in English, German and Polish languages, Try the German version. Try the Polish version.
China, Zhejiang Province
In a bilateral co-operation project, sponsored by Zhejiang Academy of Acricultural Science, DSS prototypes were designed and field validated for paddy rice.
Results from field validation trials show that sufficiently robust weed management was achieved and a potential of ~xx% reduction of herbicide input as compared to local standards was demonstrated (Ref.)
It runs in Chinese and English,, but is not available to the public.
