PHYTOPATHOGENIC FUNGUS STUDIES UNDER LABORATORY CONDITIONS

Expertise: one responsible expert by pathogen since 1993
BPL accreditation since 1998
FONGICIDE EFFICACY STUDIES ... from screening to preliminary and off season studies:

• Mode of action studies (curative, speed of penetration, systemicity, efficacy duration...),
• Formulation comparisons,
• Rainfastness



FONGICIDE RESISTANCE RISK ASSESSMENTS STUDIES

Before registration
• Method development,
 • « Baseline »,
 • Cross sensitivity,
 • Long term selectivity

After registration
• « Monitoring » across Europe,
• Specific studies on resistant strains (fitness, cross resistance,...)

    

Facilities:
• Laboratories (270m²) equipped with a vacuum area (120m²) for pathogen studies under isolated area,
 • Fully automated greenhouse (150m²) for experiment plant material production all year long
Type of trials:
• In vivo : entire plants and leaf discs,
 • In vitro : Petri dish and titration microplates

Pathogenes:
• Plasmopara viticola,
 • Erysiphe necator,
• Botrytis cinerea...
