Weeds act as competition for the same space and nutrients that crops need to grow. If and when weeds are allowed to grow in the field, the farmer will more often than not get lower grain yeilds. In crops where the seed is harvested and sold as a cash crop, this is a serious threat. In crops where the plants are to be chopped up into silage, this is not as big as a threat because the silage is going to be eaten by livestock anyway.

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.
