Lily beetle’s destructive days are numbered
TIME may be up for the scarlet lily beetle (Lilioceris lilii), a common pest that is a voracious predator of lilies and fritillaries, destroying their leaves and flowers.
The beetle larvae hide underneath plant leaves and cover themselves in their own poo for protection.
Researchers at BASF’s nematode facility in West Sussex believe that Nemasys Fruit and Veg Protection treatment may kill off the damaging pest.
Scientists think that the nematodes (parasitic worms) in the product kill the lily beetle larvae and pupae.
A Nemasys spokeswoman said: “A single treatment may be sufficient to control the pest throughout the season, but as the mature larvae and pupae are found in the top few inches of soil it is best to re-treat, ensuring the soil remains moist in summer.”
Nemasys products are available online at
nematodesdirect.co.uk and nemaslug.co.uk and can be ordered from good garden centres.
