The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1] The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been ...
The Herbicide Resistance Action Committee (HRAC) classifies herbicides by their mode of action (MoA) to provide a uniform way for farmers and growers to identify the agents they use and better manage pesticide resistance around the world. [1] [2] It is run by CropLife International [3] in conjunction with the Weed Science Society of America ...
One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [ 59 ]
The chemical, supplied by Monsanto and Dow Chemical, was a mixture of two herbicides: 2,4,5-T and 2,4-D. The former was phased-out of field use more than 30 years ago due to toxicity concerns ...

US Geological Survey estimate of 2,4-D use in the USA to 2019. The use of herbicides in US agriculture is mapped by the US Geological Survey. As of 2019, 2,4-D was the most used of the auxins. 45,000,000 pounds (20,000,000 kg) were sprayed that year, [5] compared to 2,000,000 pounds (910,000 kg) of the next most heavily applied, MCPA. [6]
2,4-DB or 4-(2,4-dichlorophenoxy)butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad-leaf weeds in alfalfa, peanuts, soybeans, and other crops. Its active metabolite , 2,4-D , inhibits growth at the tips of stems and roots.
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
