Aminocyclopyrachlor (AMCP) is a selective, low-toxicity, auxin-mimicking herbicide that provides pre- and post-emergent control of broadleaf weeds on several non-food use sites including rights of way, wildlife management areas, recreational areas, turf/lawns, golf courses and sod farms. It was conditionally registered as Imprelis by DuPont in August 2010, and first used in Fall 2010, though used experimentally since 2008 or before.

Chlorpropham or CIPC is a plant growth regulator and herbicide used as a sprout suppressant for grass weeds, alfalfa, lima and snap beans, blueberries, cane fruit, carrots, cranberries, ladino clover, garlic, seed grass, onions, spinach, sugar beets, tomatoes, safflower, soybeans, gladioli and woody nursery stock. It is also used to inhibit potato sprouting and for sucker control in tobacco. Chlorpropham is available in emulsifiable concentrate and liquid formulations.

2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C6H3Cl3O. It has been used as a fungicide and herbicide. Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly referred to simply as dioxin) as an unwanted by-product. In the course of purifying the hexachlorophene, still bottom wastes were created with concentrated levels of TCP and dioxin.

Methyldichlorophosphine (alternatively known as dichloro(methyl)phosphane, SW and methylphosphonous dichloride) is an organophosphorus compound with the chemical formula CH3PCl2. It is a colorless, corrosive, flammable, and highly reactive liquid with a pungent odor.

Lenacil is a uracil-derived chemical herbicide used to control broadleaf weeds.

Tribenuron in the form of tribenuron-methyl is a sulfonylurea herbicide. Its mode of action is the inhibition of acetolactate synthase, Group 2 / Group B of the Herbicide Resistance Action Committee's classification scheme.

Imazaquin is an imidazolinone herbicide, so named because it contains an imidazolinone core. This organic compound is used to control a broad spectrum of weed species. It is a colorless or white solid, although commercial samples can appear brown or tan.

Leptospermone is a chemical compound (a β-triketone) produced by some members of the myrtle family (Myrtaceae), such as Callistemon citrinus (Lemon Bottlebrush), a shrub native to Australia, and Leptospermum scoparium (Manuka), a New Zealand tree from which it gets its name. Modification of this allelopathic chemical to produce mesotrione led to the commercialization of derivative compounds as HPPD inhibitor herbicides.

Ioxynil is a post-emergent selective nitrile herbicide. It is used in Australia, New Zealand, Iran and Japan to control broadleaf weeds via the inhibition of photosynthesis. It is used notably on onion crops, among others, normally at 300–900 g/Ha. It was introduced in 1966. The supply of ioxynil is decreasing, as of 2019 but the herbicide remains effective.

Fluroxypyr is an herbicide in the class of synthetic auxins. It is used to control broadleaf weeds and woody brush. It is formulated as the 1-methylheptyl ester (fluroxypyr-MHE).

Prosulfocarb is a preëmergent herbicide used agriculturally in Australia, the EU, Japan, New Zealand, (since 2020), Morocco and Iran, for control of annual ryegrass and toad rush in wheat and barley crops. It was introduced to the EU in 1988 and is rapidly growing in use, with sales increasing by over 500% in France since 2008.

(2-Chlorophenyl)thiourea is a chemical compound used as an herbicide. As of 1998, the Environmental Protection Agency did not have it registered as a pesticide in the United States.

Isoproturon (IPU) is a urea class selective herbicide, which has been used to control annual grasses and many broad leafed weeds in wheat, barley, rye and triticale.

Cyanazine is a herbicide that belongs to the group of triazines. Cyanazine inhibits photosynthesis and is therefore used as a herbicide.

Butralin is a preëmergent herbicide used to control suckers on tobacco in the United States, Australia, Mozambique and, for food crops also, China. It is a dinitroaniline, first registered in the US in 1976. It was used in the EU until a ban in 2009 due to its ecotoxicity.

chemical compound

Diflufenican (sometimes called DFF) is a herbicide used to control weeds including wild radish and wild turnip weeds or suppress capeweed, crassula, marshmallow or shepherd's purse, in clover pasture, lupins, lentils or field peas.

class of herbicide

Indaziflam is a preemergent herbicide used especially for grass control in tree and bush crops.

class of chemical substances

Flufenacet is an oxyacetanilide herbicide applied before crops have emerged. It was registered for use in the United States in 1998 and the European Union in 2004.

Ethofumesate is a pre- and post-emergent benzofuran herbicide used on sugar beets to control weeds, notably blackgrasses. UK registration in 2016 is planned for preëmergent use on wheat as an auxiliary component of tank mix. Ethofumesate is used in Australia, to control wintergrasses in turfgrasses, along fencelines and tree plantations. Young weeds absorb ethofumesate through roots and shoots, and the ethofumesate inhibits respiration and photosynthesis. Ethofumesate is a Group J (Australia), K3 (Global), Group 15 (numeric), resistance class herbicide.

Dichlormid is an organic compound with the formula . The compound can be classified as the amide of diallylamine and dichloroacetic acid. It is an herbicide safener for use with maize.

It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

Endothall (3,6-endoxohexahydrophthalic acid) is used as an herbicide for terrestrial and aquatic plants. It is used as an aquatic herbicide for submerged aquatic plants and algae in lakes, ponds and irrigation canals. It is used as a desiccant on potatoes, hops, cotton, clover and alfalfa. It is used as a biocide to control mollusks and algae in cooling towers.
