The use of Agricultural chemicals is an increasingly prominent aspect of modern agriculture. As farms have become huge in size, the challenges farmers face in keeping the crops free of damage have increased. Agrochemicals are chemicals used in agriculture, to help plants and crops grow and stay safe. Agrochemicals were mainly manufactured to protect agricultural crops from pests and for augmenting crop yields. Examples of Agricultural chemicals include fertilizers, liming and acidifying agents (which are designed to change the pH), soil conditioners, pesticides, and chemicals used in the raising of livestock such as antibiotics and hormones.

Herbicides are the most common type of pesticide used, accounting for almost 90 per cent of the pesticides used by the agriculture sector.
In the broadest sense,
Pesticide active ingredients are described by the types of pests they control or how they work. People often use the term "pesticide" to refer only to insecticides, but it actually applies to all the substances used to control pests.
Well known pesticides (terms defined below) include:
Less well-known pesticides (terms defined below) include:
The following list will help you understand the wide range of types of pesticides:
Algicides kill algae in lakes, canals, swimming pools, water tanks and other sites.
Antifoulants kill or repel organisms that attach to underwater surfaces, such as barnacles that cling to boat bottoms.
Antimicrobials kill microorganisms such as bacteria and viruses.
Attractants lure pests to a trap or bait, for example, attract an insect or rodent into a trap. (However, food is not considered a pesticide when used as an attractant.)
Biopesticides are derived from natural materials such as animals, plants, bacteria and certain minerals.
Biocides kill microorganisms.
Defoliants cause leaves or foliage to drop from a plant, usually to facilitate harvest.
Desiccants promote the drying of living tissues, such as unwanted plant tops.
Disinfectants and sanitisers kill or inactivate disease-producing microorganisms on inanimate objects.
Fungicides kill fungi (including blights, mildews, moulds and rusts).
Fumigants produce gas or vapour intended to destroy pests, for example in buildings or soil.
Herbicides kill weeds and other plants that grow where they are not wanted.
Insect growth regulators disrupt the moulting, maturing from pupal stage to adult, or other life processes of insects.
Insecticides kill insects and other arthropods.
Miticides (also called acaricides) kill mites that feed on plants and animals.
Microbial pesticides are microorganisms that kill, inhibit, or out-compete pests, including insects or other microorganism pests.
Molluscicides kill snails and slugs.
Nematicides kill nematodes (microscopic, worm-like organisms that feed on plant roots).
Ovicides kill eggs of insects and mites.
Pheromones disrupt the mating behaviour of insects.
Plant growth regulators alter the expected growth, flowering or reproduction rate of plants (does not include fertilizers).
Plant Incorporated Protectants are substances that plants produce from genetic material that has been added to the plant.
Repellents repel pests, including insects (such as mosquitoes) and birds.
Rodenticides control mice and other rodents.
