Tree Injectable Imidacloprid Full Registration Soon Australia

Steve

I have been working with Bayer Environmental Science for a number of years to get this product up and running.
We have the draft label of SilvaShield 200SL, with inclusive rates for Pandanus Leafhopper.
The internal damage is pretty ordinary when using the suspension concentrate formulation, but the new solvent based formulation avoids stem damage as the pressure flow in is very low.
We also have been trialing this formulation on multi species as well with spectacular success.
As a new member l am not entirely familiar with this interface, the file attachment button will not work otherwise I would have posted the files.

Check out this thread all about attaching files.

If the files are too big in size email them to me and I can manually load them. Private Message me for my email address.

Also I brushed the topic here in this post where there's lack of label for tree injections, the lantana beetle here in Brisbane was a shocker.

Hi Trev

Good to see you are here as well, received an email from Eric this morning with an invitation to join, and did so.

I inject oxytetracycline into palms using bullets, and a needle to control lethal yellowing. The leafhopper is the vector that passes it from tree to tree. Does this product also control lethal yellowing?

vl2007

Is this product Merit?

Steve

We do not have Lethal Yellows in Australia at present,this product will kill the vector, but the only problem is the virus has already been transmitted.
Our Pandanus leaf hopper is host specific as far as l know and like a lot of hemipteran insects it would probably make a good vector.
SilvaShield 200 SL is exactly the same product as Merit Tree Injection, in the past it has been called Confidor 200SL,Merit 200SL.
In the US Merit Tree Injection is 17.1% in Australia it's 20% its the same amount of active but expressed differently 171 cc by volume to volume, ours is grams of active to volume.

How was a wettable powder supposed to go through the vascular system ... force it through with pressure? Surely not ... what happened to plant anatomy classes?

Steve

I am not refering to a wettable powder or suspension concentrate, specific solvent based formulations wont tear vascular tissue as the active ingredient is in solution.
This formulation injects at very low pressure (20psi) or less, if any at all, the stem virtually sucks it in.
The old pandanus image shows internal damage caused by imidacloprid technical material in a suspension concentrate when injected at label rates.

Steve,

I understood that this was Beyer's soluble formula of Imidacloprid but the earlier pressurised injections were using a non-soluble form that clearly required enough pressure to rupture the cells.

As you wisely point out any injection system should not require use of high pressure. My point was that it amazes me that this was not immediately obvious. Pressure was required because the suspension blocked the transport system.

Of course we could resort to foliar sprays or soil injection and avoid stem injuries altogether. Perhaps someone could explain how injected Pandanus will deal with the breach to the periderm.
