How are weeds controlled in alfalfa?

Weeds in alfalfa are controlled through a combination of cultural, mechanical, and chemical methods. Cultural practices include crop rotation and proper seeding rates to establish a dense alfalfa stand that can outcompete weeds. Mechanical control involves practices such as mowing or tillage, while chemical control typically uses selective herbicides that target weeds without harming the alfalfa. Integrated weed management strategies that combine these methods are often the most effective for long-term control.
