The product is used at application rates of 0.008–0.0155 pounds per acre (9.0–17.4 g/ha). [16] The estimated use in US agriculture is mapped by the US Geological Service and shows that from 1992 to 2017, the latest date for which figures are available, up to 120,000 pounds (54,000 kg) were applied each year.
In the same report, it added the "yield loss plus increased herbicide cost may result in an average estimated loss of $28 per acre" if atrazine were unavailable to corn farmers. [4] In 2006, the EPA concluded that the triazine herbicides posed "no harm that would result to the general U.S. population, infants, children or other... consumers." [5]
Resistance increases pesticide costs. For southern cotton, herbicide costs climbed from between $50–$75 per hectare ($20–$30/acre) a few years ago to about $370 per hectare ($150/acre) in 2014. In the South, resistance contributed to the shift that reduced cotton planting by 70% in Arkansas and 60% in Tennessee.
The combined effects of herbicides, nitrogen fertilizer, and improved cultivars has increased yields (per acre) of major crops by three to six times from 1900 to 2000. [ 3 ] In the United States in 2012, about 91% of all herbicide usage, determined by weight applied, was in agriculture.
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 ...
