Principles and methods of integrated weed management in cropping systems
2018
Verschwele, Arnd
During the last decades weeds in field crops have been predominantly controlled by herbicides, at least in developed countries. However, the weak diversity in cropping systems in combination with one-sided use of herbicides created problems like herbicide-resistant weeds. This worldwide increasing threat is still impaired by the continuous loss of registered herbicides. Consequently there is a strong need for more integrated weed management (IWM) focusing on preventive weed control. IWM is considered as a complex long-term approach by reducing weed emergence and reproduction. The key element of successful IWM is a diverse crop rotation, supported by site-specific primary soil tillage and stubble tillage. However, IWM is not fully accepted by farmers, mainly because the efficacy as well as the costs are hard to predict. Thus, more research and guidance are needed on decision support, weed thresholds and prediction models.
