Agrovista Amenity has confirmed that Lanzarta has now received full registration approval in the UK to control large pine weevil, available as a post-transplant forest application.

The insecticide has been specifically developed for the control of weevil, which is one of the most destructive pests affecting UK forestry.

Causing significant damage to newly planted conifer trees, adult beetles feed on the bark, often girdling the stem and ultimately killing the plant. On heavily affected sites, between 50% and 100% of newly planted conifers can be destroyed.

Lanzarta can now be used as a nursery pre-treatment and as a post-transplant forest application.

Supplementary applications can be made using handheld equipment such as knapsack sprayers to target later-emerging weevil generations.

Stika spruce remains highly susceptible to large pine weevil damage, with approximately 35 million Stika spruce trees planted annually, which accounts for around 50% of the UK's £2bn forestry industry. "Effective protection during establishment is critical," says Agrovista.

Containing 190g/l chlorantraniliprole, Lanzarta is a Group 28 insecticide which controls large pine weevil following ingestion of the active substance.
