What are the problem of weeds to farmers?

Weeds can harbour problem insects and crop diseases. For instance, mustard-family weeds can carry over canola diseases, making rotation a less effective tool for disease management. Immature weeds can interfere with harvesting operations. Weed seeds in harvested crops cause dockage and increase risk of spoilage.
