Description of practice

Chemical pest control uses pesticides to control pest populations. Pesticides can be sprayed or added as seed dressings. Application of pesticides may contaminate soil and water, and might have negative impacts on soil and aquatic life.

Systemic insecticides

Systemic insecticides are applied as a drench to the crop or as a granule to the soil. They are water soluble and become absorbed and distributed systemically throughout the whole plant. When insects feed on the plant, they ingest the insecticide.

Contact insecticides

Contact insecticides are commonly sprayed onto the crop. They are designed to be toxic upon direct contact with insects and include inorganic insecticides (containing metals and sulfur), organic insecticides (synthetically produced) and natural insecticides (like pyrethrum and neem oil).

Insect growth regulators

Insect growth regulators (such as Diflubenzuron which is used to control caterpillars and Hydroprene which is used to control cockroaches and moths) are used to control insect populations. IGRs makes use of insect hormones to inhibit their growth.

Rodenticides are used to reduce rodent populations by poisoning them via ingestion, either being lethal after one exposure or multiple exposures. Rodents are sometimes very harmful for agriculture.

Botanical pesticides

Tree rosin, oleoresin (produced by conifer species) and neem oil are applied as botanic pesticides. These are some of the many organic compounds produced by plants to defend themselves from predation.
