Pitcher GR is a new biorational for the suppression of Black Vine Weevil eggs and early instar larval stages. It is being hailed as a timely new tool in the IPM armoury for controlling this problematic pest.

Available from ICL

Developed by independent UK-based biopesticide company Ecospray, Pitcher GR is available exclusively in the UK and Ireland from ICL and its distributors.

Efficacy on Vine Weevel Eggs

“Based on a stabilized form of garlic extract, when applied to growing media, this active substance – Diallyl polysulphide, shows efficacy on vine weevil eggs and early instar larval stages.” ICL’s Sales Development Manager, Martin Donnelly continues “Dissolving through the cuticle, it starts a cascade chain reaction causing the egg or instar to die due to overwhelming oxidative stress.

Beneficial Nematodes

“Reducing reliance on conventional crop protection chemistry, Pitcher GR is a biorational recommended for use in conjunction with beneficial nematodes in an integrated pest management (IPM) programme,” explains Martin. “After using Pitcher GR, it is important to wait a minimum of six weeks before making a second application, or applying beneficial nematodes.”

Containerised Ornamentals

“For use in containerised ornamental plants growing outside or under protection, Pitcher GR is a very timely addition to our Vine Weevil IPM programme,” says Martin. “With the imminent loss of thiocloprid containing products, such as Exemptor, and with MET52 no longer available, growers will have to embrace a biological approach to controlling this pest."

"Used correctly, our Seeka beneficial nematodes are proving highly effective at controlling vine weevil larvae. Pitcher GR now gives growers the opportunity to bolster overall control by targeting younger stages of the pest."


To help growers, ICL will shortly be holding a series of dedicated Webinars on IPM control of Vine Weevil covering Pitcher GR: Larvae control using the Seeka range and how best to implement an integrated approach to controlling this potential devastating pest.
