Mecoprop or Methylchlorphenoxypropionsäure ( MCPP ) is a herbicide of the class of auxin herbicides. The main application is directed against broad-leaved weeds such as thistles, dandelions, winches and cranesbill. It is often used in combination with other herbicides such as similar 2,4-D, dicamba or MCPA.
