Assessing non-chemical weeding strategies through mechanistic modelling of blackgrass (Alopecurus myosuroides Huds.) dynamics

 ; Because of environmental and health safety issues, it is necessary to develop strategies that do not rely on herbicides to manage weeds. Introducing temporary grassland into annual crop rotations and mechanical weeding are the two main features that are frequently used in integrated and organic cropping systems for this purpose. To evaluate the contribution of these two factors in interaction with other cropping system components and environmental conditions, the present study updated an existing biophysical model (i.e. AlomySys) that quantifies the effects of cropping system on weed dynamics. Based on previous experiments, new sub-models were built to describe the effects on plant survi…

Field testing of IPM-based cropping systems: a diversity of experimental approaches in Europe

International audience; Integrated Pest Management (IPM) emphasizes physical and biological regulation strategies to control pests while reducing the reliance on pesticides. It is often based on combinations of control measures, because each available alternative measure might have a moderate efficiency. Field experiments are required to analyse the interactions between control measures, and to evaluate the sustainability of IPM-based cropping systems (CS). A network of European agronomists managing field experiments at the CS level was set recently, aiming at sharing data and expertise to enhance our knowledge on IPM. Comparing methodologies highlighted a diversity of approaches in CS desi…
