Under aerobic conditions in soils or pure cultures, products of bromoxynil degradation often retain the original bromine groups. The herbicide, and one of its common degradation products (3,5-dibromo-4-hydroxybenzoic acid) have been shown to undergo metabolic reductive dehalogenation by the microorganism Desulfitobacterium chlororespirans.

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 ...
4-Hydroxyphenylpyruvate dioxygenase (HPPD) is an enzyme found in both plants and animals, which catalyzes the catabolism of the amino acid tyrosine. [4] Preventing the breakdown of tyrosine has three negative consequences: the excess of tyrosine stunts growth; the plant suffers oxidative damage due to lack of tocopherols (vitamin E); and ...
Toxicity labels [1] viz; red label, yellow label, blue label and green label are mandatory labels employed on pesticide containers in India identifying the level of toxicity (that is, the toxicity class) of the contained pesticide. [1] [2] [3] The schemes follows from the Insecticides Act of 1968 [1] and the Insecticides Rules of 1971.
Mesotrione is a selective herbicide used mainly in maize crops. [1] It is a synthetic compound inspired by the natural substance leptospermone found in the bottlebrush tree Callistemon citrinus . It inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) [ 3 ] and is sold under brand names including Callisto and Tenacity.
The purpose of the label is to "provide clear directions for effective product performance while minimizing risk to human health and the environment." A label is a legally binding document that mandates how the pesticide can and must be used and failure to follow the label as written when using the pesticide is a federal offense. [4]
Dimethyl tetrachloroterephthalate (DCPA, with the main trade name Dacthal) is an organic compound with the formula C 6 Cl 4 (CO 2 CH 3) 2.It is the dimethyl ester of tetrachloroterephthalic acid, used as a preemergent herbicide with the ISO common name chlorthal-dimethyl.
Restricted use pesticides (RUP) are pesticides not available to the general public in the United States.Fulfilling its pesticide regulation responsibilities, the United States Environmental Protection Agency (EPA) registers all pesticides as either "unclassified" or "restricted use".
