In many cases, minor changes to your product label will not impact upon the original safety and efficacy assessment, but we need to check that this is the case, and whether those changes need to be supported by data.
Some label changes do not require an application. These are detailed in the Labelling Handbook.
There is specific guidance on adding undersown crops to your label.
For all other changes, submit application form CRD1 with the other documents and information required for your application.
