State and explain any five cultural method of controlling weeds

Cultural methods of weed control

• Crop rotation: controls wed that are associated with certain crops eg. Striga in maize fields.
• Cover cropping -: smoothers weeds preventing their growth.
• Flooding: controls non – aquatic weeds in rice fields.
• Timely planting: enable crops to establish earlier thus smothering weeds.
• Proper spacing: creates very little space for weed growth and forms canopies that suppress weeds.
• Clean seed bed. It starts off the crop on a clean bed to enable it to compete effectively with weeds.
• Use clean seed/ planting materials:  this prevents introduction of a new weed into the farm.
