Plant disease poses gin threat
An invasive plant disease is posing a threat to one of the UK鈥檚 favourite tipples.
A pathogen called Phytophthora austrocedri is spreading through juniper trees in Scotland, which produces 70 per cent the UK鈥檚 gin.
The warning comes from experts at the Plant Health Centre, including Professor Fiona Burnett from Scotland鈥檚 Rural College (伊人直播).
In a blog for Plant Health Week (21-27 September), Prof Burnett, along with Sarah Green from Forest Research and Prof Sarah Gurr from the University of Exeter, also highlights the threats faced by the Scotch whisky industry from diseases such as Ramularia, which can slash barley yields.
The Phytophthora austrocedri pathogen has entered Britain through the plant trade and may have got into juniper woodlands through well-intentioned planting schemes.
It lives in the soil and spreads in both soil and water, infecting juniper roots and killing large numbers of juniper trees especially on wet sites.
Although gin 鈥� an industry worth 拢3.2 billion to the UK economy 鈥� can be produced from spirits derived from a wider choice of grains or even potatoes, it relies on juniper berries for its traditional and distinctive flavour.
Luckily for gin drinkers, researchers in Scotland have found that some junipers are resistant to P. austrocedri and it is hoped that natural regeneration will allow juniper populations to recover over time. Science is also helping to identify juniper sites that are less vulnerable to the pathogen and which can be targeted for conservation and protection.
Members of the public can also take simple steps to help protect the gin industry.
These include cleaning soil from boots, bike tyres and dog paws before and after visiting forests, moors and woodlands to prevent disease spreading to new sites.
Prof Burnett said: 鈥淧lant Health Week is a chance to flag that everyone can play their part in protecting Scotland鈥檚 plant health assets. Whisky is equally at risk to gin through barley diseases which slash crop yields. But the principles of best plant health practice such as sourcing seed and plants with care and avoiding moving problems inadvertently in soil apply equally to field crops and the plants in our moorlands, gardens, forests and fields.鈥�
Prof Gurr said: 鈥淎t a time of heightened awareness of the impact of epidemics on human health, we must also remember that disease has a huge impact upon plant health.
鈥淔ood security and crop protection rely heavily on breeding for disease resistance and upon the widespread spraying of fungicides and insecticides.
鈥淗owever, despite such disease protection strategies, we still lose around 20 per cent of our crops to disease.
鈥淲e hope Plant Health Week will raise awareness that disease devastates not only human life but also crops and the very calories we need to sustain us.鈥�
Scotland鈥檚 Plant Health Centre was launched in 2018 and is funded by the Scottish Government through its Rural and Environment Science and Analytical Services Division.
It brings the plant sectors for forestry, horticulture, environment and agriculture together to co-ordinate plant health knowledge, skills, needs and activities across Scotland.
The Centre Directorate is headed up by the James Hutton Institute, and has sector leads from Scotland鈥檚 Rural College (agriculture), Royal Botanic Garden Edinburgh (horticulture and environment) and Forest Research (forestry).
