Atrazine, the second most commonly applied herbicide in the U.S., has been used for more than 50 years and “there is simply no other comparable product that offers as many benefits,” stresses David Bridges, Ph.D., agronomist and president, Abraham Baldwin Agricultural College, Tifton, GA. “Despite the phenomenal growth of the use of glyphosate in field corn, nearly 60 percent of all U.S. field corn acres is treated with atrazine,” Bridges says. Moreover, 50 percent of U.S. field corn treated with glyphosate is also treated with atrazine, he adds.
Bridges will present findings from his study at the 2012 Southern Weed Science Society Annual Meeting, which will be held next Wednesday, January 25, in Charleston, SC. In “A biological analysis of the use and benefits of chloro-s-triazine herbicides in U.S. corn and sorghum production," Bridge reports that atrazine provides irreplaceable benefits to farmers of field corn, sweet corn and grain sorghum, including weed control, application flexibility, crop tolerance and tillage compatibility.
“As the price of corn rises, the economic benefits of atrazine become even more pronounced, and it becomes even more important to keeping American farmers competitive,” Bridges reports.
Syngenta, the principal registrant for atrazine, provided resources and support for Bridges's research. His paper is part of a program by Syngenta to examine the value of atrazine in the agricultural economy. For more information about atrazine, visit www.atrazine.com.
