The use of special resistant varieties of sinapis and fodder turnip for clearing the fields of nematodes has long been known. In Europe, they are mandatory in crop rotation before beets and potatoes, as both crops suffer greatly from these pests. In addition to nematode resistance, the varieties must have a rapid initial development and cover with their roots maximum space in the soil. The roots of the turnip and the sinapis attract nematodes, but in resistant forms the enemy due to lack of food can not complete its development cycle and thus the population of nematodes in the soil is greatly reduced below the threshold of economic harmIn addition, due to the activation of microbial life due to the roots of catchcrops, residual cysts / galls in the soil are more parasitic and the corresponding nematode population is more difficult to recover. If necessary, "biofumigation" of the field can be practiced by mixing saturated resistant catch crops in the soil.

SERVAL | Nematode-resistant variety sinapis alba
SERVAL is a specially selected nematode-resistant variety of sinapis with a deep and richly branched root system. On infected areas it achieves an excellent cleansing effect from nematodes.
SERVAL is a lure and enemy for nematodes. For a full effect, a higher sowing density is recommended to cover the maximum contaminated soil layer.
ARENA | Nematode-resistant variety forage turnip
ARENA is a variety of forage turnip, which is resistant to nematodes and can be used to restore soil health.
ARENA has almost no tendency to form roots, which provides a more complete frostbite. Almost 2/3 of the valuable mass for green manure grows underground. It leaves behind a rich organic mass, loose soil layer and effectively reduces the attack of nematodes.
