Plant health risks associated with side streams from potato processing

Aims:

The main objectives of the project are to support the competitiveness of the Finnish food chain and the management of biological risks by enhancing the safe use of the recycled nutriens in agriculture and thereby reduce the amount of the generated loss and waste.

The purpose is to increase awareness and understanding of  plant health risks associated with side streams from potato processing and prevent the spread of plant pests in the potato production.

The project’s results enable the evaluation and guidance of the use of various side streams originating from the potato processing as recycled nutrients, as well as the evaluation and development of legislation within this sector.

The project will include a literature review, mostly focusing on assessing if the processing requirements regarding the side streams from potato processing, necessitated by the current fertiliser legislation , are efficient enough to prevent the spread of plant pests in potato production.

Based on this survey, the project will furthermore assess the impact of various starch potato industry processes on the survival of plant pests in potato cell sap, validate methods for testing potato wart from potato and soil samples and assess the applicability of side streams from potato processing as research matrix.
