🌱 International Day of Plant Health🌱

Today, we highlight an often-overlooked topic: plant health – vital for food security, biodiversity, and sustainable agriculture.

In our current research at Hochschule Bonn-Rhein-Sieg and Julius Kühn-Institute, we’re tackling a key question:
How can we detect plant diseases and pests before visible symptoms appear?

🔬 The answer: With the nose of chemistry!
We analyze volatile organic compounds (VOCs) that plants emit when under stress or attacked by
🦠 bacteria,
🍄 fungi, and
🪲 insect pests.

Using advanced GC-MS technology (gas chromatography-mass spectrometry), we aim to identify these unique molecular “scent signatures” and use them as an early-warning system to detect harmful organisms before they cause damage.

🧪 Our goal: to “sniff out” plant diseases and pests.

A collage of images related to plant pathology research using VOC analysis. It includes laboratory equipment such as a GC-MS system, air sampling pumps, a beetle on a leaf, decayed potatoes, and fungal-infected samples. In the center, a speech bubble over the GC-MS instrument reads: “Pflanzenkrankheiten und Schädlinge 'erriechen'” (which translates to “Smelling out plant diseases and pests”).

Wow, I learn something new every day. They talk about matrix effects in #AnalyticalChemistry but blood analysis is no doubt full of stuff like this, where taking biotin interferes with... a lot of seemingly unrelated blood tests!

Field trip to gather some first VOC samples of the invasive Asian hornet (Vespa velutina).
Really productive day, thrilled to get the data in the lab later.

Trying to wrap my head around why on Earth I thought taking instrumental analysis was a good idea. Pretty sure past me decided my life was just too easy and I needed some suffering

An open textbook on a wooden desk, displaying a detailed technical diagram with labeled components. The desk holds a white keyboard and an iMac with a dark screen. In the background, shelves with small figurines and a framed picture are visible, along with a sign that humorously reads, “You can’t buy happiness, but you can buy goats, and that’s kind of the same thing.” The room has a cozy, dimly lit atmosphere, suggesting a late-night or deep-focus study session.

In the quantitative lab at

Students keep forgetting to dry their samples before they start their analysis. So I made a sign to remind them. In hindsight maybe not the most effective way, though.

A dark wooden sign labeled in Elven script with the German text: "Probe trocknen Quanti rocken. Wasser da bis nächstes Jahr." Translation: "Dry sample, rock the Quanti lab. If there is still water we will see you again next year."

Here is the link to my YouTube webinar on batch correction in #metabolomics #analyticalchemistry. It introduces the QC-MXP software but does not do into much detail. Early next year there will be a paper and some deep dive YouTube tutorials. youtu.be/B6iGZgnLZE8?...
