In the United States as of 2014, atrazine was the second-most widely used herbicide after glyphosate, [16] with 76 million pounds (34 thousand metric tons) of it applied each year, [19] [20] nearly identical to its usage in 1974, of 76.8 million pounds. [21] Atrazine continues to be one of the most widely used herbicides in Australian ...
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".
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 ...
A crop-duster spraying pesticide on a field A self-propelled crop sprayer spraying pesticide on a field Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others (see table). The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant ...
AtzA is an atrazine-dechlorinating enzyme with fairly restricted substrate specificity and plays a main role in the hydrolysis of atrazine to hydroxyatrazine in soils and groundwater. [3] Atrazine Hydroxyatrazine is a hydrolase (an enzyme that catalyzes the hydrolysis of a chemical bond ), which acts on halide bonds in C-halide compounds.
DDT was used extensively for agricultural use in the 1950s and 1960s to control grass grub and porina moth. It was also used on lawns and for market gardens. Some 500 tons was being applied annually by 1959. By the 1970s its use was restricted and it was finally banned in 1989. Residues are still found in livestock and in marine mammals.

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.
