Arsenic - PowerPoint PPT Presentation


Overview of Herbicides Classification and Groups

Herbicides are classified based on their chemical nature into inorganic and organic types. Inorganic herbicides, such as arsenic acid and copper sulfate, do not contain carbon atoms, while organic herbicides, like glyphosate and 2,4-D, contain carbon atoms. The classification includes various groups
