Atrazine is a chlorinated herbicide of the triazine class. [2] It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), [3] soybean [3] and sugarcane and on turf, such as golf courses and residential lawns.
Atrazine is used on many U.S. crops, including corn and sugarcane. It has been banned in the European Union and several other countries and has been found to disrupt the endocrine system.
In 1990 sulcotrione was introduced for post- emergence weed control in corn. Isoxaflutole opened the market more broadly for HPPD inhibitors when it was introduced in 1996 for corn and sugarcane, and for use as a pre-emergence herbicide that could control broadleaf weeds as did sulcotrione, but also additional grass weeds.
An example of pre-emergent pesticide application is atrazine application for corn. Similarly, glyphosate mixtures are often applied pre-emergent on agricultural fields to remove early-germinating weeds and prepare for subsequent crops. Pre-emergent application equipment often has large, wide tires designed to float on soft soil, minimizing both ...
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 ...
The EPA considered much of the data submitted by the company from 2013 to 2021 to be insufficient, and found that a required study looking into the weed killer's effects on thyroid development ...
The new findings come as the application of pesticides to crops on farm fields has exploded since the 1980s. ... Application of dicamba and 2,4-D has also increased for corn crops — of which 5.4 ...
When 2,4-D was commercially released in 1946, it became the first successful selective herbicide, triggering a worldwide revolution in agricultural output. It allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crops, because it kills dicots (broadleaf plants), but not most monocots (grasses).
