UK Field Trials


Rothamsted Research has applied to release another experimental GM crop into the environment. GM Freeze led objections and many others joined us in submitting to the public consultation, which has now closed. We will update this page when Defra publishes its response to the application.

Experimental GM crops can be grown in open fields in the UK if they are granted consent by the Department for the Environment, Food and Rural Affairs (DEFRA). A list of current applications and consents is published online. This includes non-agricultural releases such as medical uses of GMOs.

When researchers apply for consent for a GM field trial they submit detailed scientific papers. These are reviewed by the Advisory Committee on Releases to the Environment (ACRE) and also made available as part of a public consultation.

GM Freeze submits evidence to most of these consultations and can also help you understand how to get your concerns across through the consultation process. Applications can be made at any time and consultations only last a few weeks so make sure you are signed up to our email list to hear about them in time to make your views known.
