Additionally, the manufacturing process for 2,4,5-T contaminates this chemical with trace amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). [4] TCDD is a carcinogenic persistent organic pollutant with long-term effects on the environment. With proper temperature control during production of 2,4,5-T, TCDD levels can be held to about .005 ppm.
Metribuzin (4-amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5(4H)-one) is a herbicide used both pre- and post-emergence in crops including soy bean, potatoes, tomatoes and sugar cane. It acts by inhibiting photosynthesis by disrupting photosystem II. [2] It is widely used in agriculture and has been found to contaminate groundwater. [3]
The industry-sponsored Herbicide Resistance Action Committee (HRAC) advises on the use of herbicides in crop protection and classifies the available compounds according to their chemical structures and mechanism of action so as to manage the risks of pesticide resistance developing. [4] The 2024 HRAC poster of herbicide modes of action includes ...
Fenoprop, also called 2,4,5-TP, is the organic compound 2-(2,4,5-trichlorophenoxy)propionic acid. [2] It is a phenoxy herbicide and a plant growth regulator , an analog of 2,4,5-T in which the latter's acetic acid sidechain is replaced with a propionate group (with an extra CH 3 ).
Indian toxicity label system Toxicity symbol for European toxicity class I and class II. Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization.
2,6-Dichlorobenzonitrile (DCBN or dichlobenil) is an organic compound with the chemical formula C 6 H 3 Cl 2 CN. It is a white solid that is soluble in organic solvents. It is widely used as a herbicide and organic chemistry building block. [1]
Agent Purple was chemically similar to the better-known Agent Orange, both of them were consisting of a mixture of the herbicides 2,4-D and 2,4,5-T and in both cases the 2,4-D and 2,4,5-T constituted equal shares of the Agent. [1] The difference was in the form of 2,4,5-T.
In 1997, it was the third most used fungicide in the US, behind only sulfur and copper, with 12 million pounds (5.4 million kilograms) used in agriculture that year. [3] Including nonagricultural uses, the United States Environmental Protection Agency (EPA) estimates, on average, almost 15 million lb (6.8 million kg) were used annually from ...
