How to identify Vine Weevil
Vine Weevil larvae, which are white, legless grubs with a brown head, feed on the roots of your plants which will cause the plant to die as a result.
Adult Vine Weevil are long, dull black beetles. They have dark yellow markings on their wing cases and are roughly 9mm long.
The adults will eat away at the leaves leaving odd shaped notches of leaf margins in the summer season.
How Exhibitline HB works
Exhibitline HB is an organic control of the Vine Weevil pest. It should be used to treat the larvae of Vine Weevil. Exhibitline HB consists of a beneficial Nematode (juveniles) species.
Nematodes are applied through irrigation systems and provide a fast and effective control of Black Vine Weevil. After Exhibitline HB has been applied, they will get straight to work by entering the natural body openings or penetrating the pest cuticle of the Vine Weevil larvae. Once they get in, they release bacteria. Bacteria develop within the insect and it dies of septicaemia. The Nematodes will reproduce inside the body of the Vine Weevil larvae which begins a cycle until the nematodes run out of a host pest.
Exhibitline H can treat the following:
• Black vine weevil (Otiorhynchus sulcatus)
• Strawberry root weevil (Otiorynchus ovatus)
• Chafer grub (Phyllopertha horticola)
How to use
Use Exhibitline HB immediately upon receipt or store in a 5ºC fridge for no more than 2 days and use it when Vine Weevil larvae are present. Apply to plants in moist soil or growing medium. Avoid application in direct sunlight and ensure there is plenty of water in the soil to make sure the root ball is treated properly. Aim to apply in the evening.
