What should we call a plant disease when the scientific name of the pathogen keeps changing?
Many diseases affecting crops and forest trees have lacked established Swedish names. Instead, people have often used the scientific name of the fungus, bacterium or virus causing the disease. But scientific names can change as researchers learn more about how organisms are related.

To make communication clearer, the Swedish Society for Plant Pathology has now recommended new Swedish names for a number of diseases affecting forest trees, sugar beet, cereals, oilseed crops and legumes.

Professor Magnus Karlsson at SLU is a former member of the naming committee behind the initiative:
“Pathogens and the diseases they cause are not the same thing. Clear disease names make it easier to communicate across research, advisory services and practice".

A PCR-loving mallard nests every year outside our PCR lab. This year’s ducklings were carefully rescued and relocated. Their mother was guided through the building to rejoin them. Together, they waddled off towards the river :)

What determines which harmful fungi thrive in our soils? 🌍🍄

A new global study published in Nature Communications reveals that the structure of the surrounding landscape plays a key role in shaping soil-borne pathogenic fungi — organisms that can affect both crop production and ecosystem health.

“Our study shows that landscape structure can be just as important as local soil conditions in explaining how plant pathogenic fungi spread and establish in the soil,” says Petra Fransson, referring to results based on soil samples from more than 500 sites across six continents.

The research shows that landscape complexity and surrounding land use influence fungal communities worldwide, and that these effects vary depending on ecosystem type and spatial scale.

Today, on the International Day of Plant Health we want to celebrate the amazing PhD students at the Department 🌱
This day, initiated by the Food and Agriculture Organization of the United Nations, highlights the importance of protecting plant health for food security, biodiversity, sustainable forestry, and resilient ecosystems worldwide. Healthy plants are essential for both people and the planet. Our PhD students contribute with research ranging from forest and agricultural plant pathology to microbiology and disease epidemiology

Together, they are helping to build knowledge for healthier forests, sustainable agriculture, and more resilient ecosystems for the future. 💚

What happens beneath our forests may be just as important as what we see above ground 🌲

In a new article in Nature, Professor Paul Kardol and colleagues highlight how different tree communities shape hidden energy flows underground through complex interactions between roots, fungi, and soil microbes. These unseen networks influence carbon cycling, nutrient exchange, and ultimately forest resilience in a changing climate.

"We were surprised to see that mixed forests didn’t lead to more functional soils. Instead, they showed slightly poorer results than some of the forests with a single tree species", says Paul.

Join us online today for Ke Zhang's docent lecture:
Scots pine blister rust in Swedish forests: current epidemics and foresight

Scots pine and Norway spruce are the backbone of Swedish forests, with major ecological, economic and cultural importance. But a damaging fungal disease, Scots pine blister rust, is becoming more severe, with recent outbreaks linked to changing weather conditions and a warming climate.

In this lecture, Ke Zhang will present new research on how the disease spreads, how climate change may influence future epidemics, and how resistant pine trees could help protect forest health in the years ahead.

Attend live online or watch the recording afterwards.

New international research platform will reduce nitrogen losses in agriculture 🌱

SLU is participating in the new international initiative AgNUE, which aims to reduce nitrogen losses in agriculture and thereby decrease both climate and environmental impacts.

Nitrogen not taken up by crops can lead to emissions of, among other things, nitrous oxide and leaching into water bodies. More efficient and sustainable solutions in agricultural systems are therefore crucial.

“What feels particularly important about this initiative is the international and interdisciplinary collaboration, which is essential for addressing such a complex issue,” says Sara Hallin.

AgNUE is coordinated by Aarhus University in Denmark and brings together 14 partners from universities and research institutes across Europe and the United States. The platform is funded with up to €24 million from the Novo Nordisk Foundation and an additional €6.5 million from the United States.

Healthy soils are the foundation of our future. They support food production, biodiversity and climate resilience, yet they are under increasing pressure.

The EU project MultiSoil aims to change that by bringing together researchers and stakeholders across Europe to develop practical ways to understand, measure and improve soil health.

Curious to learn more about Europe’s soils and what we’re working on? Watch the video and follow the project as it unfolds.
