description

Weeds are both harmful for crop production and important for biodiversity in agricultural landscapes. Moreover, we need to reduce herbicide use to limit environmental impacts. We therefore must design new cropping systems optimising all cultural techniques and reconciling agricultural production on one hand, herbicide reduction and biodiversity on the other hand. The objective of our study was to illustrate how to (1) develop models quantifying the effects of cropping systems on weed dynamics, (2) integrate interactions between weeds and other biotic components, (3) translate weed flora into a series of indicators of the impact on production and biodiversity, (4) use the model for multicriteria evaluation and multiobjective design of cropping systems.
