Atrazine was invented in 1958 in the Geigy laboratories as the second of a series of 1,3,5-triazines. [26] Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropylamine. Like other triazine herbicides, atrazine functions by binding to the plastoquinone-binding protein in photosystem II, which ...
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 .
Mesotrione may be pre-mixed with other herbicides to provide more complete weed control. For example, Acuron is the name used by Syngenta for a mixture containing bicyclopyrone, atrazine and S-metolachlor in addition to mesotrione. Brand names for mesotrione include Callisto, Instigate, Meristo, Resicore and Tenacity.

“They caused substantial damage, entire lawns and turf grass were damaged,” Cloyd said. Cloyd said armyworms haven’t been a big problem since then, but he has noticed more phone calls in 2024.
Atrazine Chlorohydrolase (AtzA) is an enzyme (E.C.3.8.1.8), [1] which catalyzes the conversion of atrazine to hydroxyatrazine. Bacterial degradation determines the environmental impact and efficacy of an herbicide or pesticide. Initially, most pesticides are highly effective and show minimal bacterial degradation; however, bacteria can rapidly ...
