Summary

Steam sterilisation or pasteurisation of soils are not permitted for weed control; along with Azadirachtin (from neem) and lime sulphur, they may be used with prior permission only in protected cropping structures and only as a single response to a particular pest problem. Soil Association Organic Standards. Paragraphs 4.10.5 and 4.11.10.

Difference

Soil Association standards have further restrictions to the EU Regulation 2092/91. Soil Association standards restrict the use of steam sterilisation or pasteurisation of soils. These methods are not permitted for weed control; with prior permission, they may be used only in protected cropping structures and only as a single response to a particular pest problem. EU Regulation does not refer to these practices.

Justification

Steam sterilisation and pasteurisation are energy intensive methods, which impair soil biodiversity and are generally incompatible with organic soil management principles. As the methods require only the use of water and energy, their absence from the EU Regulation could be interpreted as allowing unrestricted use of the methods for pest and disease control.
