Diagnostic service — Urban trees & green spaces
Identify what threatens your trees with molecular certainty.
Amoterra's Diagnostic service detects pathogenic fungi involved in urban tree decline. A standalone service, distinct from MYCOTERROIR, dedicated to municipalities.

A service dedicated to municipalities
Cities and green-space services: tree health responsibility is yours. You need fast, reliable pathogen identification.
Among our clients: Mulhouse, Roubaix, Montpellier, Paris, Versailles, Nantes Métropole, La Rochelle.
Two questions, two analyses
The service answers two complementary questions: plant health (which pathogen?) and soil biodiversity (what mycorrhizal potential?).
Plant health
You want molecular identification of the fungus causing decline?
Targeted pathogen analyses — confirm visual diagnosis, assess risk, adapt response.
Soil biodiversity
You want to know the mycorrhizal biodiversity state of your site?
Global mycorrhizal analyses — know the mycorrhizal patrimony, follow stress impact, guide management.
Pathogenic or wood-decay fungi

Mycorrhizal fungi
Analyse the mycorrhizal biodiversity of a soil
The Diagnostic characterises mycorrhizal abundance and diversity.
Abundance
- Mycorrhization rate in roots
- Number of living spores in soil
Diversity
- Taxa identification compared to the Marjaam reference database
- Distribution by genus: Archaeospora · Claroideoglomus · Glomus · Paraglomus · Diversispora · etc.
- taxa*: genus or species (from DNA sequence analysis)
Trades
A service tailored to your trades
Diagnostic is particularly relevant for urban-tree and sports-facility managers, and for landscapers supporting them.
Municipalities
Urban trees, parks, alignments: identify what threatens your tree heritage.
