Potato sprout control: How to keep mint oil as a fog?

Mint oil has been used successfully in the pre-pack sector in the UK to control sprouting. Its use in warmer storage this season is generally new.

Storage conundrum in Britain: ‘To store or to sell your potatoes?’

If crops were treated with Maleic Hydrazide (MH) pre-harvest, in line with best practice recommendations, British potato will now be facing a decision on whether to apply in-store sprout suppressants such as spearmint oil and ethylene, writes Anthony Speight in a report published by AHDB. Speight says some processing crops may have been treated already. But uncertain demand heading into spring poses the question on whether to sell potatoes that are in store at the moment or keep them for longer.

European Union: Temporary chlorpropham MRL gets green light

It’s a green light for a temporary Maximum Residue Limit (MRL) for the sprout inhibitor, chlorpropham. That level may be 0.4 mg/kg in ware potatoes. A European Union Standing Committee agreed to this in a digital vote. The temporary MRL is expected to take effect around the summer of 2021. The exact starting date depends on further decision-making within the EU. The current 10.0 mg/kg MRL will remain in force. That’s until the temporary MRL comes into effect. The use of Chlorpropham has been banned. But, ware potatoes will still be delivered under the current MRL. That’s in the 2020/2021 season.

Important potato diseases and tips to manage them in storage

This article was written by Canadian potato specialists, Dr Eugenia Banks (Ontario Potato Board) and Mark VanOostrum (WD Potato Ltd), and we publish it here with permission. They write: An essential requirement for a long storage period is that the storage conditions match the needs and the end use of the crop. The storage requirements of the crop can be assessed before harvest by doing several test digs which allow to determine – if present – the distribution and level of tuber infection. If there are risky areas in a field such as low spots that have blighted potatoes, skip those areas, do not harvest them.

Early seed potato harvest presents dry rot risk

With the Scottish seed potato harvest beginning a fortnight ahead of normal, SRUC consultant Dr Stuart Wale has reminded growers of the threat from dry rot, according to a news article published by Potato Review magazine. He recommends two fungicide options in this situation: Gavel (imazalil) and Storite Excel (thiabendazole) which can be used alone or in mixture.

How to make a potato store more efficient and get better sprout control

A well-sealed store will decrease your energy bills, and increase the efficiency on sprout suppressants like ethylene and spearmint oil. In this article, Adrian Cunnington, Head of Sutton Bridge Crop Storage Research at AHDB Potatoes shares some tips for assessing and improving your potato store. The loss of approval of CIPC will inevitably mandate change within the potato industry. For many it may mean using alternative sprout suppressants. Others may choose to go chemical-free, moving to varieties with a longer dormancy period, or by storing at lower temperatures. For all though, optimising storage conditions and reducing operating costs are likely to be high priorities.

One such factor is dormancy, say specialists at AHDB’s at Sutton Bridge Crop Storage Research unit. The current data on varietal dormancy is of variable quality and AHDB has commissioned a trial to generate relative dormancy data from a range of varieties representative of the different end markets for potatoes.
