Catch Crops and Catch Crops Mixtures

General

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 harm. In 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.
