A biorational pesticide for the suppression of vine weevil eggs and early stage instar larvae. It is approved through an Extension of Authorisation for Minor Use (EAMU) in containerised ornamental plants, both protected and outdoors.
The active ingredient in Pitcher is garlic extract. Contained within the active ingredient are a unique range of Diallyl polysulfides (DAS). It is these compounds that provide the lethal biochemistry.
- When a Vine Weevil egg or early stage instar encounters Diallyl polysulfide (DAS) molecules they penetrate through the skin
- Rate of passage through the cuticle is dependent on sulphur chain length
- Once the DAS dissolve through the cuticle of the organism the lethal biochemistry starts
- This leads to a cascade chain reaction within the organism which it can’t regulate causing it to die due to overwhelming oxidative stress
- Rate of passage through the cuticle is dependent on sulphur chain length
- The action of DAS is initiated following a reaction with intracellular low molecular weight thiols (LMT’s) and protein thiols in the organism
- The oxidative stress affects many cellular processes so it is very unlikely that resistance could ever evolve to the chemistry
