Tagetes are effective against nematodes
The marigold, an effective nematode killer
The bright orange-red flowers of the Tagetes look very pretty. At the same time, the plant is extremely easy to care for and thrives in the bed and flower box without problems. But not only her appearance makes the marigold flower a popular ornamental plant. It is also suitable for ecological nematode and pest control and thus ensures a very good soil environment.
Tagetes act like a natural soil cure
Tiny nematodes, the nematodes, are found almost everywhere in nature. The relatively small, colorless or white worms prefer moist environments. Some species are successfully used as beneficial insects in biological pest control.
Other species, on the other hand, cause massive damage to crops. These respond to the infestation with symptoms such as:
By planting marigolds, the tiny pests can be superbly controlled and the soil permanently improved.
Effect of tagetes
The marigold secretes through its roots a fragrance that attracts the nematodes. As soon as they suck on the roots or penetrate into the root system, the pretty summer flower releases a highly effective toxin, which kills the pests.
In order for the marigold to be effective, you should plant the affected areas with Tagetes for at least three months, from spring to autumn. For a thorough soil culture, plant exclusively tagetes on the infested soil. Alternatively, you can transplant the marigold and effectively curb the noxious activity of the roundworms.
Student flowers as green manure against nematodes
Some roundworm species avoid tagetes because they specialize in weeds and weeds as host plants. In this case, enrich the green manure with Tagetes and apply a not too thin mulch layer in the bed. As a result, the host plants are effectively suppressed and the nematodes die as a result. Remove wakeful wild herbs consistently so that the nourishment is removed from the nematodes.
