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 use of DDT in the United States was banned in 1972, except for a limited exemption for public health uses. Public concern about the usage of DDT was largely influenced by the book, Silent Spring, written by Rachel Carson. [9] The ban on DDT is cited by scientists as a major factor in the comeback of the bald eagle in the continental United ...

[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 ...
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.
The researchers found that YouTube's recommendations system forwarded these accounts graphic videos of school shootings, tactical gun training videos and how-to instructions on making firearms ...
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.
