Insecticide

Insecticides are used to control insect infestations. Some insecticides are incorporated into the soil (to treat grubs, worms, and other soil dwelling pests), while others are applied directly to plant foliage (to treat moths, aphids, and other above-ground pests). Most foliar applications need to be properly timed, otherwise they are not effective. Consequently, many farmers scout their fields to determine if/when insects are present.
