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".
Atrazine may be catabolized as a carbon and nitrogen source in reducing environments, and some aerobic atrazine degraders have been shown to use the compound for growth under anoxia in the presence of nitrate as an electron acceptor, [35] a process referred to as a denitrification. When atrazine is used as a nitrogen source for bacterial growth ...
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
The U.S. EPA said in the 2003 Interim Reregistration Eligibility Decision, "The total or national economic impact resulting from the loss of atrazine to control grass and broadleaf weeds in corn, sorghum and sugarcane would be in excess of $2 billion per year if atrazine were unavailable to growers." In the same report, it added the "yield loss ...
Atrazine Chlorohydrolase (AtzA) is an enzyme (E.C.3.8.1.8), [1] which catalyzes the conversion of atrazine to hydroxyatrazine. Bacterial degradation determines the environmental impact and efficacy of an herbicide or pesticide. Initially, most pesticides are highly effective and show minimal bacterial degradation; however, bacteria can rapidly ...
Alachlor mixes well with other herbicides. It is marketed in mixed formulations with atrazine, glyphosate, trifluralin and imazaquin.It is a selective, systemic herbicide, absorbed by germinating shoots and by roots.
Tyrone B. Hayes (born July 29, 1967) is an American biologist and professor of integrative biology at the University of California, Berkeley.He is known for his research in frogs, concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes male frogs, causing them to display female characteristics.
In Canada, the use and sale of 2,4,5-T was prohibited after 1985. [5] The international trade of 2,4,5-T is restricted by the Rotterdam Convention. 2,4,5-T has since largely been replaced by dicamba and triclopyr. Human health effects from 2,4,5-T at low environmental doses or at biomonitored levels from low environmental exposures are unknown.
