Exemptor given extension of use to include peat-free

Exemptor has been given an extension of use in peat-free growing media used for ornamental crop production.

The Chemicals Regultion Division (CRD, part of the Health & Safety Executive) has given an extension of authorisation for a minor use of a plant protection product (No. 1107/2009) in the UK to Exemptor, which has as an active ingredient of 10% w/w thiacloprid.

Product authorisation holder is Bayer CropScience and marketing company is Everris (ICL).

This extension of authorisation ends on the final expiry date of use for the authorised product (unless otherwise stated).

This extension of authorisation for minor uses applies to all UK parallel trade products issued under Article 52 of Regulation (EC) No 1107/2009 for which Exemptor with MAPP 15615 is the reference product.

CRD advise to use no more than two applications of any neonicotinoid insecticide (e.g. acetamiprid,

clothianidin, imidacloprid or thiacloprid) on any crop. Where a neonicotinoid insecticide has previously been used on the crop (e.g. as a seed treatment or soil treatment), use no more than a single foliar application of any neonicotinoid.

Exemptor should always be used in conjunction with other insecticides of a different mode of action.

This Extension of Authorisation relates to the use of ‘Exemptor’ (M15615) incorporated into reduced peat and non-peat based organic growing media at a rate of 400 g product per cubic metre of growing media.

The product must not be used on non-organic type growing substrates (e.g. hydroponics, rockwool, ceramic). Exemptor may be used as a compost-incorporated treatment for raising the following protected and outdoor container grown ornamental crops only: bedding plants, pot plants and hardy nursery stock.

"It is particularly good news for growers of fleshy rooted perennials susceptible to vine weevil, such as Primula and Heucheras, as well as vulnerable hardy nursery stock genus including Rhododendrons and Azaleas," says Andrew Wilson, ICL technical manager.
"The EAMU is particularly timely as, following a mild winter, vine weevil pressure is likely to be high this season and the adult beetles are starting to emerge from protected structures. Applied at the recommended rate of 400 grams per cubic metre of growing media, Exemptor provides up to 38 weeks control – effectively a full season in the annual life cycle of vine weevil."
