Biological pest control. Rows of potato plants flanked by mustard plants (yellow) on an organic farm. A farmer is hoeing the soil. The mustard plants attract the insect pest wireworm (a type of beetle larva) away from the potatoes, removing the need for chemical pesticides. Organic farms, like this one in Devon, UK, use no artificial fertili- sers or pesticides.
