Amateur gardeners accused of fuelling national potato shortage by spreading dangerous fungal blight


* Commercial farmers have suffered wettest summer in 100 years
* Downpours left fields waterlogged and much of the crop left to rot
* It has also made potatoes particularly vulnerable to fungal infections
* So-called 'late blight' is caused by fungal spores spread on the wind
* The Potato Council says 'grow your own' gardeners make it worse

Commercial farmers across the UK have suffered amid the wettest summer in 100 years, with downpours that have left fields waterlogged. Here a farmer shows some freshly dug new potatoes


Farmers say the situation has been made worse by the army of ‘grow-your-own’ gardeners. 
The Potato Council says they are responsible for spreading the blight because they can’t identify it quickly and do not know how to control outbreaks.

To blame? 'Grow your own' gardeners, 
like this woman on an allotment in Peckham, 
south London, have been accused of 
unwittingly helping to spread a disease affecting potatoes
Farmers say the situation has been made worse by the army of ‘grow-your-own’ gardeners. 
The Potato Council says they are responsible for spreading the blight because they can’t identify it quickly and do not know how to control outbreaks.

While farmers routinely douse crops in fungicides to kill off the spores, gardeners tend to avoid using such chemicals. 

As a result, even small garden or allotment plots of infected potatoes can threaten farms across a wide area.
The Potato Council warned they were responsible for a ‘disproportionate amount of overall blight pressure’ in warm, wet seasons.

Council chairman Allan Stevenson said it would be better if amateurs left the growing of potatoes to the professionals.

The Duchess of Cambridge recently told a group 
of gardeners in Newcastle that she grew her 
own potatoes, but had suffered a poor crop this year
He told The Grocer magazine: ‘People should be encouraged to grow their own vegetables to learn about the origins of their food.

‘But the blight risk is real, and it would be preferable if people bought healthy, well-produced potatoes from their retailer, rather than grow their own.’ 

The spores can survive through the winter months on vegetation, in the soil and on any potato plants that are not properly cleared at the end of the harvest.

Tesco and Sainsbury’s have warned of shortages of UK-grown vegetables and higher prices in the run-up to Christmas. 
Stores have doubled the price of popular varieties such as Maris Piper over the past year, while further increases on all types of root vegetables are expected.

Farmers will routinely douse their crops in
 fungicides in order to kill off the spores 
but that has not helped this year
Some retailers have even put up warning notices saying that fresh produce was not up to the normal ‘beauty pageant’ standard because of the rain.

The Potato Council has contacted amateur gardening organisations to produce a special blight fact-sheet and other guidance and advice on growing potatoes.

It has also recruited hundreds of ‘blight monitors’ to check on the development of late blight both on allotments and in commercial crops.
