The crucifers (Cruciferae) — among them all cabbage species, oilseed rape, and representatives of the cover crops such as rape derivatives, white mustard (Sinapis alba), fodder radish (Raphanus sativus var. oleiformis) and others — enrich the crop rotation enormously. The overabundant flower display of oilseed rape (Brassica napus) and of the crucifers coming into flower, the cover crops, and — unintentionally — the weeds charlock and wild radish (Raphanus raphanistrum), constitutes a nectar source that draws in an abundance of flying insects.
