Abstract

Soft rot caused mainly by the bacterium Pectobacterium carotovorum is a major cause of potato post-harvest storage losses. This work reports on pre-symptomatic detection and monitoring of soft rot under laboratory and commercial research store conditions by means of an array of gas sensors (specifically metal oxide, electrochemical, photoionization and non-dispersive infrared).

Two different types of time course experiments were completed. The first set of experiments, under laboratory conditions, evaluated a prototype instrument with various representative sample types for different stages of disease progression in potato tubers. This allowed for optimisation of all parameters for subsequent testing in a potato store. The second set of experiments evaluated an optimised sensor array for soft rot monitoring under realistic potato store conditions. Results showed that a number of gas sensors could detect and monitor early soft rot development with considerable accuracy.
