Optimising combinations and timings could be answer to loss of CIPC

With a new decade of challenges and opportunities ahead in the potato sector, the 30th Cambridge University Potato Growers Research Association (CUPGRA) conference at Robinson College in the UK focused on building business resilience.

By using combinations of existing sprout suppressant technology and new physiologically-targeted treatments, the possibility to achieve equivalent results to chlorpropham (CIPC) is ‘within reach’, a new study has found.

Looking at novel alternatives to CIPC, Dr Mac McWilliam, research and development director at PepsiCo, said: “We have relied on CIPC for 68 years, but it is time to think differently. Research from Cranfield University has identified combinations of physiologically targeted treatments which confer storage durations equivalent to that of CIPC in processing potatoes.”

These included applications of 1-methylcyclopropene (1-MCP) and targeted ethylene to connect the timing of application of ethylene to the physiological status of the tuber, in short and medium-term storage situations.
