Montenegro’s wine sector is facing extreme heat, drought and vineyard pest pressure, increasing the importance of monitoring, irrigation, laboratory diagnostics and precision-agriculture technology. The country’s food safety and phytosanitary authority reported that inspections continued to detect adult Scaphoideus titanus grapevine leafhoppers in Godinje, Šušunja, Lješkopolje and Nudo.
Populations were lower than during earlier monitoring, when adults were also recorded in Jelenak. Harvesting was already underway in some monitored vineyards, while grapes at other locations had been picked because of extreme heat and drought. Scaphoideus titanus is the principal vector associated with Flavescence dorée, a major grapevine disease in Europe. Detection of the insect, however, does not confirm that vines are infected, as vector surveillance and phytoplasma testing are conducted separately.
Climate and pest pressure increase demand for vineyard data
The combination of changing grape maturity and continued pest surveillance is increasing the value of timely information for growers. Early harvesting can limit dehydration and quality deterioration during heat, but it can also affect the balance between sugar, acidity, phenolic maturity and potential alcohol. Producers therefore need more detailed information on how individual vineyard blocks are developing. This creates demand for vineyard sensors, weather stations, soil-moisture monitoring, remote sensing and laboratory analysis.
The same systems can support irrigation decisions as drought conditions intensify. Insufficient water can reduce yields and stress vines, while poorly timed irrigation can influence berry composition and wine quality. Precision irrigation allows growers to use soil and plant information to target water application rather than treating an entire vineyard uniformly.
Vineyard structure creates different technology investment models
The 2024 Agricultural Census recorded approximately 2,553 hectares of vineyards in Montenegro. Of that area, about 495 hectares were operated by family agricultural holdings and 2,058 hectares were controlled by business entities. The census counted 1,562 family holdings with grapevines and 18 business entities, combining a substantial business-operated production base with a fragmented group of smaller growers.
Larger operators can spread the cost of automated weather stations, mapping, remote sensing and laboratory capacity across larger areas. Smaller family farms may face more difficult investment economics. Shared services could provide an alternative, with agricultural laboratories, producer associations and specialist agronomy companies offering monitoring without requiring each grower to own the equipment.
Weather stations could serve several nearby vineyards, while drone or satellite analysis could be purchased periodically and laboratory testing conducted centrally. Disease-surveillance providers could also monitor several producers under standardised protocols, creating a business model based on access to vineyard information rather than direct ownership of technology. Montenegro’s relatively small geographic scale could support deployment of such services across multiple wine-growing areas. Digital platforms could combine weather data, pest observations and vineyard records to generate alerts, while coordinated surveillance and digital disease maps could help address risks that extend beyond individual properties.
Traceability and laboratory services gain importance
Vineyard monitoring can also strengthen traceability. Premium wineries can document monitoring, treatments, grape origin and harvest conditions for quality control and regulatory compliance, including when selling into demanding export markets. Climate variability makes consistency between vintages more difficult, increasing the importance of information that helps producers respond to weather conditions.
Laboratories could see additional demand as growers rely more heavily on data. Plant-pathogen detection requires specialist testing, while grape and wine production involves repeated analysis of sugar, acidity and other quality parameters. Precision agriculture also increases the role of agronomists, since sensors and software only provide value when their information supports practical vineyard decisions.
Agriculture support programmes underpin investment
Montenegro’s agriculture policy already includes support for vineyard investment. The agriculture ministry launched a dedicated 2026 support call for primary viticulture investment, while a separate programme supporting wine-sector processing and innovation closed after requested support reached the available budget ceiling. The level of requested support indicates investment demand where financing is available.
Future support can distinguish between straightforward capacity expansion and technologies designed to improve vineyard resilience, including monitoring systems, irrigation controls, diagnostics and data tools. Disease management also requires measures beyond detection. Growers need information on vineyard hygiene, treatment timing, removal of infected plants where required, and management of abandoned or unmanaged vines that can contribute to wider phytosanitary risks.
For smaller producers, access to these services may be more practical than direct ownership of precision-agriculture equipment. The latest surveillance does not indicate an immediate wine-industry crisis. The phytosanitary authority reported lower Scaphoideus titanus numbers than in earlier monitoring, while detection of the insect alone does not establish the presence of Flavescence dorée. The development instead highlights the growing importance of managing biological and weather-related variables through more timely vineyard information.
