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.
Why do weeds need to be removed what will happen if they are not removed from the field?
Weeds are unwantedvplants which grown along the useful crops. Weeding is required because weeds are competitive plants as they reduce the useful crop yield by acquiring space, fertilizers and nutrients from the soil.

Because they are plants competing to survive in a limited space, weeds are actively removing nutrients from the soil to grow taller, stronger and healthier each day. Proactively managing nutrient levels and eliminating weeds are the best ways to ensure crops have the nutrition they need for the entire growing season.
