Weeds are a problem to crop growers because they compete with the plants for air, water, and nutrients, and they usually win. They choke the plants, and their hedge like features don't allow the plants to get any sunlight. They harbour pests and diseases within them. And, of course, they look bad, and make the entire garden or flower bed look bad too.

How can herbicides improve crop?
Herbicides kill weeds. A selective herbicide will attack specific weeds only and not harm the crop. Weeds grow in farm land (like everywhere else). With the care, such as fertilizer, applied to the crops, the weeds also benefit from it growing and spreading and seeding which will eventually choke out the crops without any herbicide maintenance. Some weeds can grow taller than the crops shaded them to the point that they receive no sunlight and die. Herbicide is part of any farm or nursery for their crop maintenance.
