European sugar supplies gained ground in 2025 as coordinated pest management strategies reduced populations of the reed glass-winged cicada, the insect vector responsible for bacterial diseases threatening sugar beet crops across Germany and neighbouring regions.

The South German SBR Task Force reported that sugar beet yields and sugar content in the current campaign exceeded 2024 levels, following implementation of integrated control measures combining resistant varieties, adjusted crop rotations and targeted insecticide applications. Cicada populations decreased compared to previous years, reducing infection rates in commercial beet production.

The improvements matter to industrial bakers because SBR (Syndrome Basses Richesses) and Stolbur diseases have caused yield losses ranging from significant reductions to complete crop failures in affected areas since the pest emerged as a commercial threat several years ago. Germany remains a major European sugar beet producer, with Südzucker AG operating as one of the continent's largest sugar manufacturers.

Over 150 agricultural specialists, government representatives and crop processors convened at Südzucker's Offenau facility on 15 October 2025 to assess control effectiveness and coordinate research priorities. Dr Georg Vierling, Head of Beet Cultivation and New Plants at Südzucker AG, indicated that emergency insecticide approvals will be required again in 2026 to maintain population suppression whilst permanent approval pathways are pursued.

"Our medium-term goal is to obtain regular approval for effective insecticides against the reed glass-winged cicada," Vierling stated. "Accelerated and simplified approval procedures for these plant protection products are therefore urgently needed."

The regulatory framework remains uncertain. The Task Force has requested permanent insecticide approvals, modifications to EU agricultural regulations that currently limit bare fallow periods and expanded research funding for breeding programmes, storage stability studies and biological control alternatives.

Breeding research focuses on developing beet varieties with tolerance or resistance to the bacterial pathogens. Current programmes address the genetic mechanisms governing host-pathogen interactions, aiming to reduce dependency on chemical controls over the longer term.

The cicada's range continues expanding geographically, now affecting potato and vegetable crops alongside sugar beet. The South German SBR Task Force, established in October 2023, coordinates experimental work across designated model regions and comprises representatives from grower associations, the Institute for Sugar Beet Research in Göttingen, and Südzucker AG.

For industrial bakers monitoring ingredient markets, the 2025 results indicate stabilisation rather than resolution. Sustained control measures and regulatory support will determine whether European sugar beet production can maintain sufficient volumes to prevent supply disruptions or price volatility in coming seasons.
