  3. Weed modeling: Why? • Proximate • fun • profitable • Ultimate • science (research, education) • technology (tactics, strategy, policy) (c) 2009 Niels.Holst@agrsci.dk

  4. Models are thinking tools Models help us formulate notions about the dynamics of the different species that an ecosystem comprises. AP Gutierrez 1996 (c) 2009 Niels.Holst@agrsci.dk

  5. Modeling for weed science • Research • integration • analysis • idea generation • Education • theory • practice (c) 2009 Niels.Holst@agrsci.dk

  6. Models make you think The purpose of models is not to fit data but to sharpen the questions. S Karlin (c) 2009 Niels.Holst@agrsci.dk

  7. A diversity of models • 134 scientific papers • 60 weed species • 40 crops Holst et al. (2007). Weed Research 47: 1-14. (c) 2009 Niels.Holst@agrsci.dk

  8. Modeling life cycle • Formulate • Implement • Test • Publish (c) 2009 Niels.Holst@agrsci.dk
