Problems and perspectives in weed management

Despite the wide use of herbicides in the past century, their use is decreasing due to rising resistance phenomena, the absence of discovery of new modes of action, and more regulatory restrictions. On the other hand, several tactics and technologies have been developed recently, providing alternatives from mechanical, cultural, robotic, and natural product use perspectives that could profitably enhance weed management within the agroecosystem and usher in a new paradigm of weed management that integrates chemical and non-chemical weed management practices. In the next future, herbicides will remain an important tool for weed management and will be increasingly complemented by other innovative tactics and tools from an integrated weed management perspective. This integrated approach would thus preserve the chemical and transgenic technology for future generations.
