Ensure stewardship recommendations are followed
The new Stewardship recommendations on Chlorpropham (CIPC) this storage season (2013-14) have limited its use in low temperature stores to only one application, before pull down to holding temperature. Crops in stores that have been configured correctly, and treated soon after loading is completed, have been holding well, even at dose rates below the maximum permitted on the label. However, in some other stores it is acknowledged that sprout regrowth is occurring and where this has happened, ethylene has been used. Some other stores have had an application of spearmint oil.
NAAC applicators group chairman, Nick Green says, “All of the CIPC applicator members are sticking robustly with the Stewardship group recommendations to treat low temperature stores only once with CIPC and they are actively helping store managers with alternative sprout control strategies.” He stresses that sprout control is most successful in stores where positive ventilation systems are used to achieve a uniform distribution of the CIPC fog.
David Walker, Chairman of the Fresh Potato Suppliers Association (FPSA) comments that it is crucial that the industry stick to the Stewardship Guidelines on CIPC use as the industry cannot afford to have any further MRL exceedances.
There are pressures on stores and managing crop supply onto the market is going to be challenging. This season is demonstrating that ensuring that stores are fit for purpose and having a clear sprout control strategy is vital. The further in advance that you can plan unloading, may well determine how successful the season is.
