Oilseed radish is used as a phytosanitary crop that suppresses populations of beet cyst and root-knot nematodes. The crop's root system induces the hatching of larvae from cysts but prevents their development and reproduction.

crop Oil radish,
where this is mentioned in the description.
The crop exhibits resistance to the beet cyst nematode Heterodera schachtii, as well as root-knot nematodes of the species Meloidogyne chitwoodi, Meloidogyne fallax, and Meloidogyne hapla. The mechanism of action involves root exudates stimulating the hatching of larvae from cysts; however, the lack of conditions for feeding and development leads to the death of the pest population, thereby interrupting its life cycle.
Genetic resistance to the beet cyst nematode is determined by the dominant gene Hs1Rph, localized on chromosome d. In breeding practice, the effectiveness of pest suppression is classified by resistance levels, such as BCA 1 or BCA 2, and varieties capable of simultaneously affecting Heterodera schachtii and Meloidogyne species are designated as having dual resistance.
