Reduction also possible in the 2025 field trial: challenges due to frost and site conditions
In 2025, we once again conducted a field trial together with Certis Belchim to test and improve the VineForecast algorithm. As in the previous year, this showed that the algorithm can be used to minimise plant protection measures without the vines being more severely affected by diseases. However, the evaluation of the results was not very favourable, especially for Oidium [...]
Plant protection documentation from 2026 - What will change for your business
Plant protection documentation from 2026 will bring important changes for agricultural and horticultural businesses. From 1 January 2026, extended documentation requirements will apply to the use of plant protection products. The aim of the new regulations is to improve the traceability, transparency and standardisation of records within the EU. For companies, this means more mandatory information, clearer requirements and the gradual [...]
Plant protection reduction through VineForecast in the 2024 field trial
Efficient and sustainable plant protection is a cornerstone of modern viticulture. In 2024, Certis Belchim tested the VineForecast algorithm in field trials on a Müller-Thurgau vineyard in Spiesheim, Germany. The aim was to reduce the number of plant protection measures to a necessary minimum while ensuring effective control of Peronospora and Oidium. The result was promising: up to [...]
VitiMap - The infection map for Peronospora and Oidium
Since 2019, VineForecast has been helping wineries to minimise the risk of crop failures due to fungal infections or weather risks and to optimise their spraying schedules. To do this, the system calculates disease and weather forecasts without the need for weather stations. Instead, artificial intelligence calculates microclimate and disease forecasts with a resolution of 25 metres x 25 metres. Our aim is to provide a responsible and realistic [...]
Botrytis cinerea (grey mould, grey mould rot) - Fungal diseases in viticulture #3
Grey mould (Botrytis cinerea) is a mould fungus or parasite that can cause considerable damage to green vine tissue and other cultivated plants such as fruit trees or ornamental plants. Wine grapes such as Pinot Noir, Chardonnay or Semillon are usually particularly susceptible to botrytis due to their high sugar content. One of the most striking symptoms of Botrytis infestation is a greyish fungal turf. For this reason, botrytis is often also [...]
Oidium (powdery mildew of grapevine) - Fungal diseases in viticulture #2
Oidium (powdery mildew of the grapevine) is an important fungal disease in viticulture, which is known in particular for its negative effect on the flavour of the wine. The infestation is visible in the form of a completely mealy-grey coating on the young shoots of the vine. However, the similar name should not lead to confusion. This is because the two fungal diseases differ greatly in terms of [...]
The influence of leaf wetness on vine diseases
Leaf wetness - the key variable for the prognosis of a fungal disease Our last guest article by plant biologist Janna Einöder was about downy mildew and how it can infect and damage vines. The central variable for an infection of the vines with the fungal disease is the duration of leaf wetness, because only if vine leaves are wetted with water for a sufficiently long [...]
Peronospora viticola (downy mildew of grapevine) - Fungal diseases in viticulture #1
Like all plants that grow in a natural environment, vines and their development are heavily dependent on the weather. Sufficient rainfall, good soil quality and moderate sunlight are a guarantee for optimal plant growth - and make the winegrower happy. Unfortunately, however, it is not only the grapevine that is heavily dependent on the weather, but also its worst enemies are [...]
