Development of CIPC best practice recommendations for low-temperature (pre pack) box stores


Until its final use in October 2020, CIPC was the most important sprout suppressant used in GB potato stores. Because of its importance, AHDB Potatoes funded a programme of research on CIPC covering the efficiency of application, its uniformity of distribution in stores, residue removal and alternatives to CIPC. This study was designed to expand on work in an earlier project, which suggested sprout control in low temperature stores could be improved by making applications earlier, while crops are warmer, during the period of pull-down to holding temperature.

The aim of this work reported here was to determine if the effects of this pilot trial could be repeated, and, if so, how useful this may be as a means of improving sprout control in crops stored at low temperature.

CIPC was applied once as a hot-fog, at 50% (7g tonne-1 ) and 100% (14g tonne-1 ) rates, to replicate boxes at 10°C, 7°C or 3.5°C early in storage (during temperature pull-down) or after a period of storage at 3.5°C. Store temperature at the time of application, did not have an important effect on tuber CIPC deposit concentration, with application rate having the main effect.
