摘要: Some generic herbicides remain relevant to current and future cropping systems despite re-registration in the European Union reducing the number on the market, particularly for minor crops and uses. They will continue to play a major role in minor crop production and in weed control in broad-acre crops. Indeed, the cost and efficacy of some generic herbicides and/or the possibility of the introduction of herbicide tolerant crops in Europe is reducing the incentive to discover and develop new active substances. However, increased registration standards and/or the lack of flexibility in usage to meet the demands of modern cropping systems have already resulted or may result in the reduction in usage of other generic herbicides in major crops. Conversely, current changes in weed infestations may favour the use of some generic herbicides at least in the short term. Herbicide resistance has resulted in the increased usage of some generic herbicides and the decreased usage of others.
