Pesticides are used to help both home gardeners and farmers protect their plants from insects, weeds and/or fungi. A pesticide is any substance or mixture of substances used to alter the life cycle of any pest. Pesticides can be a naturally derived or synthetically produced substance. They can also be an organism, for example, Bt which is used to control a number of insect pests. Pesticides are also referred to as crop protection products.
