Early methods of weed control included mowing, flooding, cultivating, smothering, burning, and crop rotation. Though these methods are still important, other means are perhaps more typical today, particularly the use of herbicide (plant-killing) chemicals. Another technique is to introduce insects that attack only the unwanted plant and destroy it while leaving the crop plants unharmed.
The mechanization of farming practices throughout the world has revolutionized food production, enabling it to maintain pace with population growth except in some lessdeveloped countries, most notably in Africa.
