Vine weevil (Otiorhynchus sulcatus)

Improving control of vine weevil on hardy nursery stock

Chemical control of vine weevil larvae is difficult due to the withdrawal of the most persistent products for use in growing media and to current restrictions on using the remaining products on flowering plants and/or in peat-free substrates. Growers need more information on effective chemical control of adults. Available biological methods for vine weevil control within Integrated Pest Management (IPM) programmes include entomopathogenic nematodes and a fungus (Met52). However, growers lack confidence in Met52 and current nematode application methods are labour-intensive. This project will address key knowledge gaps to improve control methods on hardy nursery stock.
