Save our tatties! New approaches for virus control in Scottish potato crops.
Potato is the second most important food crop in the UK, and the underpinning seed potato industry contributes >£1 billion to Scotland’s economy. Aphid-vectored viruses threaten potato harvests because infected crops are downgraded or destroyed. Historically, Scotland has maintained low virus levels in potato crops, but this is changing due to the warming climate, new virus variants, loss of crop protection products, and aphid resistance to insecticides.
