Agrovista Amenity is pleased to announce its appointment as an approved distributor of Lanzarta, the newly authorised solution for controlling Hylobius abietis (large pine weevil) in Sitka spruce and other pine woodland.
The recent Emergency Authorisation (EA) for Lanzarta, manufactured by Syngenta, marks a significant milestone for the UK forestry sector, enabling forestry managers to safeguard newly planted and naturally regenerating saplings from the damaging effects of Hylobius weevil. The authorisation, secured by Confor (Confederation of Forest Industries) on behalf of the industry, permits the sale of Lanzarta between 15 April and 13 August 2025.
Application is allowed once per season within forest settings between 15 April and 30 September, using a knapsack sprayer for targeted treatment of young trees.
Containing the active ingredient chlorantraniliprole, Lanzarta offers an effective and environmentally responsible solution to the growing Hylobius problem. Its advanced SC liquid formulation binds quickly and securely to tree bark, preventing wash-off and ensuring long-lasting protection against feeding pests. By protecting young trees through the crucial early years, Lanzarta helps reduce restocking costs, ensures more consistent woodland establishment, and allows natural pest populations to diminish over time.
“Hylobius weevils pose a significant threat to young woodland, and the approval of Lanzarta is a major step forward in ensuring effective protection,” says Ed Smith, Landscape & IVM Manager at Agrovista Amenity. “With its long-lasting binding properties and ease of application, this product will be an invaluable tool for forestry managers looking to safeguard their investment and promote sustainable woodland growth.”
Sitka spruce, the dominant conifer species in UK forestry, is particularly susceptible to Hylobius feeding damage. Approximately 35 million Sitka saplings are planted annually, making up around 50% of the country’s £2bn forestry trade. The lack of effective treatment options in recent years has left reforestation efforts vulnerable to severe losses, highlighting the importance of Lanzarta’s introduction.
Incorporating Lanzarta into an integrated pest management approach—alongside cultural control measures such as extended fallow periods, ground cover management, and habitat manipulation—can further enhance protection against Hylobius weevils.
Agrovista Amenity will be distributing the product nationwide to support forestry professionals in protecting young trees and promoting woodland establishment.
