Severe Crop Losses Due to Stolbur Plant Disease

Mon 9th Jun, 2025

A troubling plant disease is wreaking havoc on the agricultural sector in Germany, leading to significant crop losses for farmers, particularly in the production of sugar beets and potatoes. Initially impacting sugar beets, the Stolbur disease has now spread to threaten various vegetables, including potatoes, celery, and other crops.

In Baden-Württemberg, the Ministry of Agriculture has reported not only yield reductions but also quality deterioration in crops such as beetroot, celery, cabbage, onions, and carrots. The spread of Stolbur is attributed to a specific species of leafhopper, which poses a serious threat to local supplies of potatoes, vegetables, and sugar.

The President of the German Farmers' Association has expressed deep concern over the rapid spread of the reed leafhopper, noting its movement from Baden-Württemberg through Rheinland-Pfalz, Bavaria, and Hesse, and now reaching northern regions, including Lower Saxony and Saxony-Anhalt. There is a pressing call for effective measures to combat this pest.

According to agricultural representatives, the situation is dire, particularly in southwestern Germany. Reports indicate that last year, farmers faced yield losses of up to 25% in all significant sugar beet cultivation areas, with sugar content severely diminished. In the potato sector, losses have been as high as 70% in some instances.

Experts from the state farmers' association highlight that the viability of some farming operations is now in jeopardy, as the disease evolves into a substantial economic risk for entire regions. They underscore the urgent need for the regular approval of effective plant protection products, alongside targeted support for practical research into resistance breeding and sustainable control strategies.

Despite the severity of the situation, agricultural associations and authorities have noted that there is no evidence to suggest that Stolbur poses health risks to humans. Additionally, any potatoes or vegetables exhibiting rubbery textures or signs of decay are not permitted to enter the marketplace.
