The Applicant Guide: Application Requirements for Trials Permits

Trials Permits

If you wish to carry out experimental/research and development work on an

you must apply for a Permit for Trials Purposes ("Trials Permit", previously known as an Experimental Approval) which will allow storage and use of the active substance/product for the experimental work.

A Trials Permit may not be necessary if the experimental active substance and/or plant protection product is not going to be released into the environment See 'What type of research and development work will require a Trials Permit' in The Applicant Guide.

See The Applicant Guide for full details of each Permit type. The following summarises the information to be submitted for each application type.

Administrative Trials Permit

For this type of application you will need to submit:

  1. Covering letter explaining your application
  2. Completed CRD 7 application form. There are no restrictions on the number of active substances that can be included on an individual application form. However, separate application forms will be required for microbial ("biological") pest control agents that are to be used as plant protection products. A separate fee will be required for each application form (see the guidance document on application fees); and,
  3. If any of the restrictions detailed in The Applicant Guide will provide difficulties in carrying out the experimental work then this should be indicated in the covering letter so that we can consider this aspect when we process your application. In this situation you will need a separate application form for each active substance.

Extrapolated Trials Permit

For this type of application you will need to submit:

  1. Covering letter explaining your application.
  2. Completed application form CRD1
  3. Relevant correspondence (including any previous advice from CRD and if relevant/available, a copy of any product authorisation(s)).
  4. Reasoned scientific cases to address the consumer, environmental and operator exposure areas of the risk assessment;
  5. Reasoned scientific case justifying the maximum area on which you wish to carry out your experimental work.

Consumer-Assessed Trials Permit

For this type of application you will need to submit:

  1. Covering letter explaining your application.
  2. Completed application form CRD1.
  3. Relevant correspondence (including any previous advice from CRD and if relevant/available, a copy of any product authorisation(s)).
