The Agricultural Technical Institute for Seed Potato
inov3PT's missions is to provide solutions and innovations to the players in the sector (seed potato growers and Growers Organisations, laboratories, breeders, technicians, experimenters, etc...) in order to consolidate the strenghts of the French seed potato but also to transfer the results and develop their impact.
inov3PT also provides reference services, technical support, expertise and training, both nationally and internationally.
​
inov3PT is financed by seed potato growers and, as an agricultural technical institute, also benefits from a CasDAR grant as part of the National Agricultural and Rural Development Programme (PNDAR).

SaveTuber project
​
A key step towards a biocontrol solution
​
FN3PT/inov3PT and the CNRS began collaborating in 2012 to identify cultivable microorganisms capable of combating Dickeya and Pectobacterium. The SaveTuber project is a key step towards developing a biocontrol solution that can be used to protect against these pathogens.

The Ralstonia solanacearum species complex (RSSC), one of the most damaging pests worldwide includes species Ralstonia solanacearum, R. pseudosolanacearum and R. syzygii. The genetic diversity of R. solanacearum in mainland France remains poorly characterized.
The work presented in this publication provides a valuable tool for epidemiological studies of these strains.

Blackleg
​
Preserving the quality of seed potato
​
Blackleg disease is a major cause of plant rejection. A collaboration between the FN3PT and the CNRS's Institute for integrative biology of the cell (I2BC) is seeking to improve knowledge and molecular diagnosis of this disease. This work will lead to proposals for new practices to limit the agronomic and financial losses caused by this disease.

COMITE NORD
​
A variety of workshops
​
On 2 July, almost 180 seed potato growers and field staff, came to find out about the trials set up by the Comité Nord. The workshops were varied : blackleg, fertilisation, weed control, late blight, viruses and even a demonstration of palox washing. The inov3PT team was on hand to run the 'research' centres on blackleg and brown rhizoctonia.

The Pseudomonas sp. PA14H7 strain has previously shown interesting activity against the bacteria responsible for blackleg and soft rot in potatoes.
Further understanding of this strain is essential to optimise its use as a biocontrol agent.

Phylea project
​
Knowing the age of tubers
​
Against a backdrop of climate change and the withdrawal of synthetic sprout inhibitors, defining the physiological age of tubers is becoming essential for better management of decisions on planting, storage instructions, processing and marketing. The main aim of the Phylea project is to identify a rapid tool for predicting this physiological state.
