Weed management refers to the practices used to control unwanted plants, known as weeds, that compete with crops for resources like sunlight, water, and nutrients. Effective weed management helps improve crop yields and maintain healthy ecosystems. Techniques can include mechanical methods, such as tillage, and chemical methods, like the application of herbicides. Integrated weed management combines various strategies to minimize weed growth and prevent resistance. This approach may involve crop rotation, using cover crops, and promoting natural predators. By employing multiple methods, farmers can create a more sustainable and effective weed control system that benefits both agriculture and the environment.
