Sticky nightshade

(Solanum sisymbriifolium)

Sticky nightshade comes from South America and is related to the potato. The catch crop Sticky nightshade is suitable for the control of potato cyst nematodes and improves the soil structure.

We introduced this crop in the Netherlands in 2001 and, together with the University of Wageningen, we have succeeded in making this crop more suitable as a cyst nematode killer.

Sticky nightshade kills about 70% of the nematode population, provided the crop has been able to develop well.

The nematode-reducing effect is almost the same as that of soil decontamination (80% control) and considerably greater than that of black fallow (50% killing).
