What if plants are telling us more than we can see?
In crop protection, many decisions are still made after stress has become visible: after symptoms appear, performance drops or a problem is already underway.
However, plants begin reacting long before we see damage. When they’re hit by pests, disease, environmental pressure or treatment effects, they are already shifting their internal chemistry – well before anything is visible to the eye.
This is where metabolomics becomes valuable: not as a buzzword, but as a way of reading the chemical signals a plant produces, and understanding what those signals are responding to before the symptoms show.

From symptoms to signals
Growers, breeders and technology developers are working in a more complex crop protection landscape: fewer conventional tools, increasing resistance, climate variability and growing pressure to demonstrate performance with stronger evidence.
Traditional approaches often tell us what has happened. Metabolomics can help explain what is happening inside the plant right now, and why.
As Dr. David Liscombe, Vineland’s Senior Research Scientist in Biochemistry, explains: “Plants are responding much earlier at a biochemical level. Metabolomics lets us measure those signals before symptoms appear.”
That shift matters. It moves the questions from reaction to interpretation: “what went wrong?” to “what is the plant dealing with, and what should we do about it?”
Why this matters now
For product developers, breeders and sector partners, this prompts a different kind of question: not simply whether something worked, but why it worked, when the signal appeared and what that could mean for future decisions.
Those questions are becoming increasingly important as the sector looks for more predictive, precise and sustainable approaches to crop protection.
For many organizations, the problem isn’t too little data. It’s knowing which signals actually matter, early enough to shape product development, screening, validation or positioning decisions.
Metabolomics can help reveal:
- Early chemical indicators of plant stress
- Differences in plant response across treatments, varieties or growing conditions
- Markers linked to resilience, susceptibility or treatment response
In other words, it adds a new layer of evidence, one that leads to better questions, stronger interpretation and more confident decisions.
Turning complex signals into practical insight
At Vineland Research and Innovation Centre, our work in plant metabolomics is focused on exactly this challenge: translating complex chemical data into clear biological answers that can be applied to real horticultural and product development questions.
The promise is not simply more data. It is better interpretation by connecting what’s happening in the plant’s chemistry to the what matters: stress, resistance, product performance and crop resilience.
That has implications for teams developing crop protection products, biologicals, biostimulants, resistant varieties or diagnostic tools; and for anyone trying to understand plant performance before the outcome is obvious.
As Dr. Liscombe notes: “The long-term opportunity is predictive. As we build datasets and validate biochemical markers, we move toward tools that help industry make decisions before problems become visible or costly.”
A more predictive future for crop protection
For the horticulture sector, this points to a broader shift: crop protection decisions that are less about reacting to damage and more about decisions based on the evidence for how plants actually respond under pressure, and acting sooner.
This is the kind of applied science that becomes most valuable when it is shaped around real industry questions.
The next opportunity in crop protection may not come from spotting symptoms sooner, but from understanding what plants are telling us earlier.
