Tagetes patula tall (BIO) is a specially selected, tall-growing Marigold known for its exceptional effectiveness against harmful nematodes in the soil. This organic variety distinguishes itself from regular Marigolds by its strong root growth, deep rooting, and wide root branching. This brings the plant into much closer contact with soil organisms, significantly enhancing its effectiveness against soil nematodes.
While many Marigolds are primarily valued for their ornamental value, Tagetes patula tall BIO was developed with a clear agricultural and ecological function: naturally suppressing root nematodes without chemical pesticides. This makes the species particularly valuable for organic vegetable gardens, crop rotation, soil improvement, and sustainable agricultural systems.
Tagetes patula tall BIO responds to nematode infection by releasing a toxic, natural compound in the root zone. This substance has a nematicidal effect, specifically against soil nematodes that penetrate the root.
The most effective results are seen in the control of Pratylenchus penetrans, a common and harmful root nematode that mainly causes problems in crops such as potatoes, carrots, onions, leeks, strawberries and various greenhouse vegetables.
Important to know:
| Fights well | Do not fight directly |
|---|---|
| Pratylenchus penetrans | Cyst nematodes |
| Root-penetrating nematodes | Root knot nematodes |
| Other infecting species | Stem nematodes |
Nematodes that do not penetrate the roots are therefore not eliminated by this chemical reaction. Nevertheless, the plant has an indirect positive effect on soil life by improving overall soil health, which can limit disease formation in the long term.
Because this variety is 100% organically grown, it can be used safely in organic cultivation methods. The plant contains no chemical residues and contributes to a living, healthy soil structure. This makes Tagetes patula tall BIO particularly suitable for:
✔ organic vegetable gardens
✔ soil restoration after intensive cultivation
✔ crop rotation and rotation systems
✔ small-scale and professional agriculture
The best results are achieved by allowing the plant to develop for a full growing season. The longer and deeper the rooting, the stronger the effectiveness against nematodes.
Besides active nematode control, Tagetes patula tall BIO offers a second major benefit: soil improvement. The plant produces abundant green foliage, which—just like its extensive root system—is converted into rich organic matter after it dies.
The result:
better soil structure
increased air and water permeability
stimulation of beneficial microorganisms
healthy growing soil with stronger crop development
This makes the Tagetes not only a fighter, but also a builder of fertile soil.
Although this variety focuses on its functional aspects, Tagetes patula tall BIO does have ornamental value. The flowers appear in shades of yellow, orange, and brownish-red and attract beneficial insects such as bees and hoverflies.
Modest in ornamental value, but exceptionally powerful in cultivation value.
