Fungi and Compost Team Up to Fight Plant Nematodes
In the world of farming, tiny worms called plant‑parasitic nematodes can cause big problems for crops. Scientists have found that certain fungi, known as nematophagous fungi (NF), can help keep these worms in check. A new review looked at how combining these fungi with organic matter—like compost or mulch—might work better than using either alone.
Rigorous Selection of Evidence
The researchers followed a strict method to pick studies. They started with over 600 papers and ended up keeping just 33 that met their criteria. This careful selection gives confidence that the conclusions are solid.
Which Fungi Make the Cut?
- Trichoderma – the most common choice in commercial products.
- Paecilomyces – appears more often when organic matter is added.
- Other promising but rarely field‑used types: Talaromyces, Pochonia, and Arthrobotrys.
How the Partnership Works
The alliance between fungi and organic matter seems to help the fungi colonise plant roots more effectively. This, in turn, boosts enzymes that break down soil components and improves overall soil health. The right kind and amount of organic matter, the choice of fungal species, local soil conditions, and timing all influence how well the system works.
Beyond Pest Control
These fungi also help recycle nitrogen and keep soil structure stable. That means they offer multiple benefits to farms, not just pest control.
What’s Still Unknown?
- Performance on large‑scale farms.
- Cost‑effectiveness for farmers.
- Detailed biological mechanisms.
A Greener Future
Overall, pairing fungi with compost shows promise for a greener way to protect crops. This approach could align with global goals such as reducing hunger, using resources wisely, fighting climate change, and protecting land ecosystems.
