Additional information on atrazine’s registration review, reregistration, and food tolerance reassessment is available in the atrazine dockets: Community water systems (CWS) are required, under the Safe Drinking Water Act, to monitor for atrazine. Atrazine’s effectiveness and safety is well documented throughout the United States and around the world, with nearly 7,000 scientific studies conducted on the product. Atrazine is useful in the farming fields or to in the crops to kill the weeds. It is used in primarily in agriculture, with the greatest use on corn, sorghum, and sugarcane. Atrazine is an herbicide widely used for control of broadleaf and grassy weeds. United States Environmental Protection Agency, In September 2020, EPA released the Interim Registration Review Decisions for atrazine, propazine, and simazine, Atrazine ecological exposure monitoring program, Triazine cumulative human health risk assessment, FIFRA Scientific Advisory Panel Meetings on Atrazine, The Preliminary Work Plan (June 2013) described our process for reevaluating atrazine, recent actions, planned human health and ecological risk assessments, and the expected review timeline, The Final Work Plan (December 2013) addressed public comments received on the Preliminary Work Plan and finalized our anticipated schedule for registration review, Atrazine Ecological Risk Assessment (June 2016) evaluated potential risks to animals and plants, Letter to National Corn Growers Association on registration review of atrazine (August 2019), Atrazine Regulatory Update (October 2019), Atrazine Proposed Interim Registration Decision (December 2019), Atrazine Interim Registration Decision (September 2020), 2006 Atrazine Interim Reregistration Eligibility Decision (RED) (PDF), Memorandum of Agreement with registrants (2004) (PDF), View Atrazine Monitoring Program Data and Results, 2006 Atrazine Interim Reregistration Eligibility Decision (PDF). Under the AMP, CWSs are selected for intensive monitoring based on a history of atrazine use and a screen of EPA's data collected under the Safe Drinking Water Act. Taking more medication will not improve your symptoms; rather they may cause poisoning or serious side-effects. Atrazine is a member of the triazine chemical class, which includes simazine and propazine. Using farm machinery to cultivate weeds from fields adds to farmers’ labor, fuel and equipment costs and increases the potential for soil erosion. A watershed can be decommissioned from the monitoring program if the 60-day running average falls below the CE-LOC for two consecutive years. If a watershed shows atrazine concentrations above this level of concern in any two years of monitoring, atrazine registrants must initiate watershed-based mitigation activities in concert with state or local watershed programs to reduce atrazine exposure. This monitoring program is required by the 2003 Atrazine Interim Reregistration Eligibility Decision (IRED) and the 2004 Atrazine Memorandum of Agreement (MOA). We do carry a full line of selective herbicides of which many are labeled for use on Bermuda. Fits soil-saving conservation tillage systems. To a lesser extent, it is used on residential lawns and golf courses, particularly in the Southeast United States. What is atrazine used for? Atrazine History. Data from the U.S. Environmental Protection Agency (EPA) show that farming without atrazine would cost corn growers $28 per acre in lost yield and/or increased weed control costs. In the cumulative assessment, EPA reviewed all available scientific data, including published toxicity and epidemiology literature. For ecological risks, each of the triazines (atrazine, propazine, and simazine) was assessed separately. Atrazine’s history dates back more than 50 years. Atrazine 4L is a restricted use post-emergent and pre-emergent herbicide formulated by Drexel Chemical Company. This website is focused primarily on atrazine-specific legal matters. Atrazine is a controlled-use herbicide that is a water-soluble white powder that is odorless. Atrazine is one of the most widely used herbicides in the U.S., and is found in 94% of U.S drinking water tested by the USDA — more often than any other pesticide. The information is being presented to enable the public, the press and decision-makers at all levels of government to make decisions based on sound science and in accordance with the principles of the Data Quality Act. It is used to safely control annual broadleaf and grass weeds in cornfields, sugarcane fields, and turfs. Specifically, atrazine is a chlorotriazine herbicide.1It is used for broadleaf weedsboth before and after they sprout. Farmers use atrazine to control weeds on well over half of the country’s corn acreage, about two-thirds of sorghum acreage and 90 percent of its sugar cane. View Atrazine Ecological Exposure Monitoring Program Data and Results, View Atrazine Data Collected under the Safe Drinking Water Act. Research has proven the positive effect atrazine has on farm production: Among dozens of herbicides evaluated by scientists, atrazine is the only product which provides all of the following key agronomic features: Atrazine is a popular weed control tool because it is economical to use, extremely effective against a spectrum of weeds, and very safe to the crop. Het remt de fotosynthese. View Atrazine Monitoring Program Data and Results. There is a reason that atrazine is one of the leading herbicides; unlike many other herbicides, atrazine has a wide spectrum of uses, applications, and utility. In July 2018 as part of EPA’s registration review process, the Agency released the cumulative human health risk assessment for the triazines. The herbicide is broad-spectrum and is effective against broadleaf weeds and grasses. An estimated 7 million people were exposed to atrazine in their drinking water between 1998 and 2003.The highest levels of contamination are in the Midwest where it is widely used on corn fields. Atrazine is an herbicide produced by Syngenta AG, a global company based in Switzerland. There is a reason that atrazine is one of the leading herbicides; unlike many other herbicides, atrazine has a wide spectrum of uses, applications, and utility. Atrazine is in a group of man-made systemicherbicides called triazines. Atrazine is a chemical compound widely used as an herbicide in commercial crops and home lawn care. As a pre-emergent, it prevents germination of weedy broadleaf and cool-season grass seeds, and as a post-emergent it kills actively growing annual cool-season weeds. Atrazine is usually applied once during the growing season (USDA NASS, 2000). For more than half a century, atrazine has been a mainstay of corn, sorghum and sugar cane farmers for its proven control of a broad range of destructive weeds. As part of the decision, EPA finalized mitigation measures to protect human health and mitigate potential ecological risks. Because the runoff washes the chemical into streams, rivers, and groundwater, it’s one of the most common pollutants found in American waters. Atrazine is an herbicide widely used for control of broadleaf and grassy weeds. The triazines have a common mechanism of toxicity, and therefore EPA has conducted both individual chemical and cumulative human health risk assessments. That’s not even the worst part. These mitigation activities can include, for example, education, stewardship and outreach programs for growers and distributors. children who crawl and play on lawns treated with atrazine or simazine and, workers who mix, load, and apply atrazine. As part of registration review and decades of study, EPA is considering amendments to the 2004 Memorandum of Agreement that would end the requirement for continued drinking water monitoring under the AMP. Read the simazine human health risk assessment. Over the years, the Agency has consulted with the FIFRA Scientific Advisory Panel (SAP) on a variety of atrazine topics. Read the propazine human health risk assessment. Do not use more than prescribed dose. (. It has also been used to keep weeds from growing on both highway and railroad rights-of-way. In Australia, atrazine is used to control weeds in summer crops such as sorghum, maize and sugarcane, and it is also widely used in Western Australia for control of weeds in lupin and Triazine Tolerant (TT) canola. Also, you may apply atrazine to an entire terraced field with tile outlets if you use no-till and high crop residue management practices (i.e., remove little or no crop residue). In particular: Upon publication of the Federal Register notice, the atrazine Interim Registration Decision will be available in docket # EPA-HQ-OPP-2013-0266. The SAP is composed of independent scientists who advise on technically challenging scientific assessment issues. Related terms: Biochar; Contaminant; Adsorption; Crustacean; Groundwater; Herbicide Atrazine is used primarily on corn, but also on other crops. In this document EPA is finalizing the following new, stronger protections to reduce exposure to atrazine. Atrazine is a member of the triazine chemical class, which includes simazine and propazine. Atrazine is een onkruidverdelgingsmiddel dat behoort tot de groep van chloortriazines, samen met onder andere simazine. Atrazine is an herbicide used to control weeds. The Agency has consulted with the FIFRA Scientific Advisory Panel on 12 occasions on various topics regarding the evaluation of atrazine data and key aspects of its risk assessments since 2000, all of which are listed in the table below. Since the program's inception, up to 33 watersheds have been monitored for atrazine in corn-, sorghum- and sugarcane-producing areas. It is used on golf courses, Christmas tree farms, and in residential landscaping. Production experts estimate yield advantage in sugar cane ranges from 12 to 50 percent. As you explore AtrazineFacts.com you will find timely, factual information which allows farmers, journalists, bloggers... and others, to stay up to date with atrazine litigation and related coverage. EPA currently regulates on an aquatic plant Concentration Equivalent Level of Concern (CE-LOC) of 10 ppb as a 60-day average concentration, which ensures that atrazine levels will not cause significant changes in aquatic plant community structure, function and productivity. This reduces soil erosion from U.S. cropland by 56 to 85 million tons per year, according to an analysis by Paul Mitchell, a University of … The average number of herbicide applications on the typical US corn crop is 1.5 (USDA ERS, 1997a). It is the most common chemical contamination in the ground water of the United States. The totality of available atrazine monitoring data collected through the AMP is robust and comprehensive, which enabled the EPA to refine and characterize its most recent (2018) human health risk assessment.
