R414 CIPC Application in Box Stores

Aim: To evaluate the impact of modified application practices on the distribution of CIPC in box stores and to determine how store parameters influence CIPC behaviour.

Industry Challenge

CIPC (Chlorpropham) is an important sprout suppressant used during storage. Applications above 36 and 63.75g/tonne for fresh and processing sectors respectively are no longer permitted in the UK. Therefore, it is essential for the potato industry to establish ways of optimising use of the chemical in this sector, which is dominated by box storage.

Collaboration

Sutton Bridge crop Storage Research (SBCSR) and the University of Glasgow

Approach

Trials will determine whether modified CIPC application practices can be used to improve sprout suppression in box stores. For example, the use of coverings to prevent fog dispersal into store roof spaces, the balance of airflow and the recirculation of CIPC fog using low volume speed-controlled fans. These will be assessed for their effects on CIPC distribution, residue levels, fog particulate behaviour, sprout control efficacy, CIPC leakage and potential for reducing CIPC inputs.
