pesticid

A pesticide is a substance used to kill a pest, and in a farming context a pest is anything that attacks or competes with crops. Hence, there are many different types of pesticides: for example, insecticides kill insects, and herbicides kill weeds. The chemicals used in pesticides can sometimes be toxic to humans, however, so organic farming endeavours to use natural rather than synthetic substances as pesticides.
