Bad news for weeds
IPMwise is an online 'Decision Support System' (DSS), which can assist proffessional weed control in winter wheat in Spain. In the PhD thesis titled:
Adapting the Decision Support System CPOWeeds to optimize weed control in northern Spanish conditions, by Jose Maria Montull, Univerity of Lleida, 2016
detailed descripstions are provided on the the biological models, IT design and results from field validation experiments.
IPMwise is a new IT design based on the same principles and results. IPMwise can:
- on a field level quantify needs for weed control and optimize (minimize) input of herbicides accordingly.At the same time, legal requirements are fully met, and measures for herbicide resistance management have also been included. These measures include both options for ontrol of biotypes of weeds, which have already become resistant, as well as measures to protect against new resistance development. In the Danish version of IPMwise, also mechanical treatments can be recommended in selected crops where herbicide treatments are sparse or very expensive.
- provide various overviews of effiacy: 1) of single herbicides, 2) of 2-3 way herbicide tankmixtures
- on all herbicides in a selected crop during a full growing season
Today's challenges in professional weed management
In conventional weed management, in particular hree conditions must be taken into account:
- Several older herbicide mode-of-action (MOA) have been prohibited or subjected to serious restrictions
- No new herbicide MOA are in the pipeline
- The remaining MOAs are used more intensively, causing still more comprehensive and widespread occurences of herbicide resistance.
The newly developed online tool, IPMwise, offers decision support for weed management, which makes the crop grower and advisors well prepared to mananage these challenges, both today and tomorrow.
Main features
In IPMwise you can apply your own prerequisites as a base for advice. For instance:
- enter your own prefered level of weed control
- use your own or prefered herbicide products, including the ones in stock, making it possible to utilize them in an optimal way
- use your own herbicide prices to minimize your spraying costs
- save and find again your own scenarios for calculations, e.g. fields, herbicide products, tank mixtures and weed populations - which are all useful information, when planning also the next growing season.
IPMwise can be used from current online devices (PC, tablet, cell phone) and in most browsers (Internet Explorer, Crome, Safari) - also in the field.
User interfaces in IPMwise have been tested by selected farmers and specialists to be immediately understandable and applicable - also in a busy growing season.
About IPM Consult
IPM Consult ApS was established in 2014 by Per Rydahl and Ole Mission Bøjer. Both have a history at Aarhus University (AU) in the field of agroecology and DSS for weed control. IPM Consult cooperates also with others, both Danish and foreign universities on innovation in weed management. Contact: Per Rydahl, mail@ipmconsult.dk
