By the end of the 1950s, atrazine was introduced for weed control on railroad tracks and rights-of-way and in com production in Europe. The initial federal approval in the United States occurred in December 1958 when the US Department of Agriculture (USDA) registered Geigy Atrazine 50W for use in com and for nonselective weed control in noncrop areas. In 1959 Atrazine 80 W was registered, which in 1970 was trademarked as AAtrex and quickly became a leading herbicide in the United States. 

Up to the late 1960s, only dry formulations of atrazine were available. Ciba-Geigy Corporation later developed the first water-based, flowable concentrate formulation of an herbicide, AAtrex 4L, which was approved on January 15, 1970. This development launched a new era in herbicide formulation technology. The water-based formulation improved the manufacturing process, minimized dust, was easier to package and to load into application equipment, and easier to mix. Gradually, more and more farmers who used atrazine switched to the liquid formulation, which is now the preferred formulation. 

Ciba-Geigy also improved atrazine dry formulations, developing a 90% WDG - AAtrex Nine-O - that greatly minimized dust. Approved by the USEPA on December 10, 1975, it was the first WDG formulation sold in the United States. 

AAtrex Nine-0 Ciba-Geigy next developed AAtrex Nine-O, a 90% concenttation of atrazine in a WDG. AAtrex Nine-0 attracted immediate interest when launched in 1979 because of its handling qualities. The granules flowed freely from the bag and were easier to measure. This type of formulation was new to growers, and it fit in an important agricultural niche. It now is a major atrazine formulation.
