The role of models in management and conservation of weeds

Session 7 - Options and perspectives in weed managementEASPEEcolDurCT1; Weeds are both a harmful crop pest and an important component of biodiversity. Moreover, herbicide use must be reduced to limit its impact on environment, and weed control must now combine numerous management techniques with partial efficiency aiming at preventing weed occurrence. Biological regulations of weeds by other biotic components could also contribute to control infestations. Thus, new cropping systems are needed, combining numerous techniques and aiming at both maximising weed-related biodiversity and minimising weed harmfulness.[br/]Weed dynamics models are increasingly used to design innovative cropping syst…

Parameterizing the "grassland" module in the multispecific model FlorSys

2013

EAEcolDurCT1; The multispecies model FlorSys can predict the effects of cropping systems on the dynamics of weed communities in annual crops ; however, it is not configured to predict the fate of weeds in permanent cover such as grasslands. We realized the simulation of a weed seed rain in controlled conditions to estimate the percentage of weed seeds intercepted by a grass cover. Parameters of this linear model will be used to develop a new sub model in FlorSys to be able to simulate weed dynamics in temporary grasslands. We used twelve weed species selected on the basis of specific morphological characteristics and observations made in the experimental set up of SOERE ACBB (Observatory En…
