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.
Precision farming practices including the use of global positioning systems (GPS) and geographic information systems (GIS) are applicable not only to harvesting operations but to other farm mechanization operations including precision application of agrochemicals i.e. applying a pesticide or a crop nutrient where it is required and at the appropriate concentration rather than using blanket coverage.
