A lack of effective chemical options in oilseed rape has accelerated the rise of cabbage stem flea beetle (CSFB). This beetle is now pest enemy number one in this crop, with its management resting on a rapidly developing, variable and complex set of alternative solutions.

Without effective chemical protection, CSFB has become more problematic. Critically, the pest can destroy a plant’s growing point and cause crop failure. Learn about the beetle’s life cycle and the factors that influence crop risk.

Our research has identified the key components of an integrated pest management (IPM) strategy for CSFB and used a traffic-light code to indicate the current reliability for control. Effective management relies on a combination of these components.

CSFB has developed resistance to pyrethroid insecticides to various degrees, so it is essential to target – even avoid – sprays as much as possible.
