Pitcher

Pitcher GR The new biorational approach against Black Vine Weevil Granular biorational insecticide

Part of an IPM solution to the problem of Black Vine Weevil

No resistance or re-entry periods

Low impact on non-target organisms

Pitcher GR

DID YOU KNOW? ICL trials have demonstrated the efficacy of Pitcher when used as directed (see next page).

Pitcher is the new biorational pesticide for the suppression of Black 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.

How is it created?

How does it work?

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

The action of DAS is initiated following a reaction with intracellular low molecular weight thiols (LMT's) and protein thiols in the organism

This leads to a cascade chain reaction within the organism which it can't regulate causing it to die due to overwhelming oxidative stress

The oxidative stress affects many cellular processes so it is very unlikely that resistance could ever evolve to the chemistry

When garlic is subject to mechanical stress, it releases two sulphur compounds which creats a range of DAS

Application

Rates of use

Pitcher is a granular biorational insecticide which is applied as a topdress over containerised ornamentals. Application can be via gloved hand (not a preferred method of application) or a suitable handheld application device.

Maximum individual dose = 240kg per Ha per season This converts to 24g per m2 Based on trials data two applications at 120kg per Ha provides meaningful suppression of vine weevil eggs (reference Fig 1).

When to apply It is important to know when to apply Pitcher for maximum efficacy and therefore understanding the Vine Weevil life cycle is a key part of utilising this product.

This converts to 12g per m2 for a single application .

Application timing is critical in order to affect eggs and young instars while they are near the surface of the container. Always water in following application in order to activate the granules.

It is important to note that all stages of the lifecycle can be present throughout the year in protected crops. It is important that you check your plants in these situations for the pest.
