Therefore, it is essential that the available products are used appropriately, resistance management strategies are implemented, that the drop-leg technique is used to avoid pollinator exposure and preferably that the pest threshold is achieved. The most common pests are: – Brassica pod midge (Dasyneura brassiceae): the adult lays eggs in the pods and the larvae feed on the inside of the pod wall, leading to pod-shatter. Biscaya and Mospilan are good options for chemical control. – Green peach aphid (Myzus persicae): they can infect crops already at emergence and transmit the Turnip yellows virus (TuYV), with an infection rate of 60% in Spain. Using a pymetrozine is the only viable alternative. – Rape stem weevil (Ceutorhynchus napi): the larvae bore through the stem during the spring for up to 5 weeks. – Pollen beetle (Meligethes aeneus): the adults feed at the bud stage, causing abscission blind stalks. Indoxacarb, thiaclopridacetamiprid and pymetrozine are currently the options for chemical control.
