Description

Atrazine was first registered for use in the U.S. in 1958. It quickly became the preferred herbicide of corn growers, controlling both grasses and broadleaf weeds and being used either as a postemergence or preemergence application, unlike the primary alternative herbicide of the time, 2,4-D (Muller 2008). Over 50 years later, atrazine is still an important weed management tool for corn growers, and was the most widely used herbicide until recently when only glyphosate was used on more acres.
