A plant protection product (PPP) may only be used according to its authorisation. The areas of use shall be specified on the label. Therefore, all plant protection products that are to be used in walk-in tunnels must be risk assessed and authorised for such use. Please use our new guidance if you want to apply for an authorisation for use in walk-tunnels.
Cultivation of raspberries in a walk-in tunnel.
Cultivation in walk-in tunnels has become more common. A walk-in tunnel is an un-heated, covered cultivation area and the structures are large enough to walk in and work inside.
A plant protection product that is authorised for field uses has not been risk assessed for the conditions in a tunnel. The risk assessment for field uses is not relevant to estimate the risk of exposure for those who use the product in the tunnel or to estimate the residues in the crop. Correspondingly, a plant protection product authorised for use in green houses has not been risk assessed for walk-in tunnels as it lacks relevant risk assessment concerning effects on the environment (ecotoxicity and environmental fate) as well as effects on those who live nearby the field (residents).
If you need to use a plant protection product in a walk-in tunnel, you may only use products authorised for such use. The authorised areas of use for a plant protection product shall be stated on the label and in the directions of use. This means that a plant protection product is allowed to be used in walk-in tunnels if such use is included as an area of use on the label.
If you are a holder of an authorisation and would like to have your product authorised also for use in walk-in tunnels you must apply for an amendment. If you would like to apply for a new product, the use in walk-in tunnels and relevant risk assessments must be included in the application.
The assessments that are required for an authorisation for use of a plant protection product in walk-in tunnels are
a risk assessment for use in fields for the evaluation of effects on the environment (ecotoxicity and environmental fate) and of effects on residents
a risk assessment for use in green houses for the evaluation of exposure of operators, workers and residues in the crop
an assessment of efficacy, either for green house or field uses
Even if your plant protection product is already authorised for use both in green houses and in fields you must apply to get the product authorised for use in walk-in tunnels. If the use in walk-in tunnels is already covered by the current authorisation, for instance in terms of doses and application rates, no further risk assessments will be required.
The Swedish Chemicals Agency has made a temporary guidance for an application for use in walk-in tunnels. Corresponding information is planned to be included in the guidance document of the Northern Zone at its next update.
