Aminocyclopyrachlor is a chemical compound of chlorine from the group of pyrimidines .
properties
Aminocyclopyrachlor is a white crystalline solid with a characteristic odor. It is a weak acid.
use
Aminocyclopyrachlor, its potassium salt and methyl ester are used as a herbicide . It is structurally similar to aminopyralid and was developed by DuPont . It was approved in the USA in 2010. The effect is based on the influence of the auxin . The compound was assessed by EFSA in 2005. In 2011, the New York Times reported that aminocyclopyrachlor was blamed for conifer death. In the European Union and in Switzerland, aminocyclopyrachlor is not approved as a crop protection agent.
