Preservation and biodegradation laboratory

Breeding under laboratory conditions of the most important timber pests (Hylotrupes bajulus, Lyctus brunneus, Trichoferus holosericeus) and of certified fungal strains that degrade wood in different service conditions (Basidiomycetes, Ascomycetes, Deuteromycetes) can be undertaken. These organisms are used for the evaluation of the protective effectiveness of wood preservatives and the natural durability of wood genotypes.

research

- In field tests and realistic tests for the evaluation of eco-friendly wood preservatives
In field tests have performed in accordance with the European standards or in some experiments the standards had modified to obtain a result that permit of evaluating the prevision of service life of wooden object.
 
- Laboratory tests
Laboratory tests are performed in accordance with the European standards.
Screening tests and accelerated decay tests are performed before to start a standard test on new product.

- Natural durability of domestic and non domestic wood species (e. g. Chestnut, Paulownia, Eucaliptus, Douglasia…ecc.)
The knowledge of natural durability allows of using wood species with respect to the hazard class and the service life of wooden artefact. The Knowledge of natural durability allows a more rational utilize of wood limiting the use of wood preservatives only when they are really necessary and promotes the use of local natural resources.

service

- Efficacy tests of wood preservatives against fungi and insects and tests for the determination of the natural durability of wood species in accordance with European standards:

Efficacy against basidiomycetes fungi with laboratory test (application by vacuum- pressure: UNI EN 113, threshold value or conferred durability; application by surface treatments: UNI CEN TS 839)
Efficacy against basidiomycetes fungi with in field test (UNI EN 252)
Efficacy against soft rot (UNI CEN TS 807)
Efficacy against blue stain fungi (UNI EN 152-1 e UNI EN 152-2)
Efficacy against Hylotrupes bajulus (preventive action: UNI EN 46-1 and UNI EN 46-2; eradicant action: UNI EN 1390)
Efficacy against Lyctus brunneus (UNIEN 20-1 and UNI EN 20-2)
