Naturally protects plants against various harmful nematodes in the soil, such as rose nematodes (which cause rose fatigue), diverse negative root nematodes, potato cyst nematodes, and beet cyst nematodes.


The product is a concentrated blend of specifically acting herbal concentrates and is non-toxic to humans, animals, and the environment. The product is not persistent; it breaks down in the soil and leaves no residues behind.


Nematodes – Soil Nematode Concentrate provides preventive action against pests in the soil. The substance is absorbed by the plant roots, thus enabling them to establish their own defence mechanism. Parasitic nematodes will no longer feed on the roots. Consequently, their population decreases, and the nuisance will eventually cease altogether.


Edible crops can be safely consumed.

Directions for Use

Nematodes – Soil Nematode Concentrate can be applied in ornamental or vegetable gardens, on balconies or on your lawn.


Administer preventively as soon as the plant, shrub, or tree begins to sprout, especially if there has been significant past damage. Even when harmful nematodes and damages are already visible, Nematodes – Soil Nematode Concentrate can be applied.


Shake Nematodes – Soil Nematode Concentrate before use. Pour or spray with coarse drops onto a damp soil, preferably before rainfall. Otherwise, generously water the soil with 5 to 10 mm of water.


Nematodes – Soil Nematode Concentrate remains effective for about 4 weeks. The treatment can be repeated if necessary.





Preventive – minor infestation/20 ml/1 litre water/20 m²

Curative – severe infestation/40 ml/1 litre water/20 m²


Stored away from direct sunlight in a cool, dark place, this product remains of high quality for over a year, even after opening.


Background Information

Rose Fatigue

A common ailment in roses. The culprit is a minuscule nematode that gnaws at the roots, hindering the rose’s growth and flowering. Rose fatigue arises from these tiny worms attacking the roots. This disease manifests as roses having many flowers, sparse leaves, and constant aphid problems. Planting a new rose? Ideally, place it where a rose hasn’t been before to prevent infestation in the new rose. If this isn’t feasible, it’s recommended to dig at least 50 cm deep and introduce fresh soil. Treating the soil preemptively with Nematodes – Soil Nematode Concentrate prevents issues and stops nematodes from thriving.


Potato Cyst Nematodes – Potato Fatigue

wo types of potato cyst nematodes exist: Globodera rostochiensis (yellow potato cyst nematode) and Globodera pallida (white potato cyst nematode). These are highly specialised nematodes that in the open ground, recognise only the potato as their host plant. Without nearby potato roots, these nematodes remain dormant within the cyst. As soon as the potato plant emits specific attractants, they become active and seek the root system. Larvae penetrate the root system and hinder plant growth. Without potato cultivation, a cyst’s content can survive up to 15 years. Thus, once infected, it remains infected! At high densities, the damage can reduce yields by up to 80%.


Beet Fatigue – White/Yellow Beet Cyst Nematode

With the white beet cyst nematode, plants sporadically lag in growth. From the six-leaf stage, plants can fall away. Root system damage reduces water uptake, causing wilting on dry days. The root system of affected plants is bushy and heavily branched. Tiny white cysts, the size of a pinhead, can be seen on the roots. Yellow beet cyst nematodes die off substantially during non-host plant cultivation. The decline can reach up to 70%, unlike white beet cyst nematodes, which diminish by about 35%. The infection is rarely found on plots with a rotation of host plants in a ratio of one to three or more. Beet varieties resistant to white beet nematodes aren’t resistant to the yellow beet cyst nematode. Even resistant cover crops barely affect this nematode’s population.


Free-Living Nematodes

Other free-living nematodes mainly cause damage in cold, wet springs. They are found in all light soils, such as sandy soils, valley soils, loam, and light clay soils. It’s typical to see rows of normally growing plants alternating with rows of lagging ones. Within a row, affected and unaffected segments might alternate. The Netherlands has identified about ten different types of free-living nematodes. Apart from growth retardation, the nematode causes a bushy root system and truncated roots. Crops with taproots, like sugar beet, carrot, and chicory, suffer significantly from free-living nematode infestations. Potatoes, onions, maize, peas, and beans are also susceptible.
