FERA Science has unveiled a new DNA barcoding test to support UK potato growers in tackling wireworm infestations, a pest that continues to cause significant crop damage and economic losses.

The test enables growers to accurately identify wireworm species present in their fields, allowing for targeted management strategies. By distinguishing between different Agriotes species, the tool helps inform decisions on cultivation practices and crop protection measures, reducing the risk of costly yield losses.

Wireworms, the larval stage of click beetles, have become an increasing concern for UK potato production in recent years as changing climate patterns and reduced pesticide options create favourable conditions for their spread. The new diagnostic tool offers growers a scientific approach to mitigate these risks.

FERA Science said the DNA barcoding method is fast and reliable, providing results that can guide integrated pest management (IPM) plans. The test is part of a broader effort to provide farmers with precision tools to improve resilience against pest pressures in a sustainable way.
