Polyphagous Shot Hole Borer (PSHB) treatment protocols and delivery methods

Over the past 10 years the Polyphagous Shot Hole Borer (PSHB) has reared it's ugly head in several countries (US, Israel, South Africa) and different control and treatment strategies have been developed.

I would like to find out some practical experiences that have been learnt in the field.

What chemicals have the best results (short term and long term)?
What organics and bio stimulants are recommended to boost tree health?
What is the optimal treatment intervals for reactive treatment vs preventative treatment?
Which tree genus responds best to which treatment protocol?
Is truck spray effective, and which surfactant works best to penetrate the tree's vascular system?
As an arborists what are the advantages and disadvantages of the professional injection systems?
What injection systems are best for private use?
Research that was published in the Journal of Economic Entomology in January 2019 concludes that:

"There are no sustainable control options for polyphagous shot hole borer other than maintaining tree vigor and removal of severely infested host material."

It also evaluates the effectiveness of therapeutic treatments of an injected systemic insecticide containing emamectin benzoate (EB) alone and in combination with a systemic fungicide.

Does anyone have experience with the injection of emamectin benzoate formulations that are not specifically designed for tree I.V.?
Right now the only labeled product with emamectin benzoate active ingredient is TreeAge. Right now the product is still patented and cannot be distributed under any other name. The only way TreeAge is to be applied is as an injection. Are you asking about different application systems like Quik-jet? After having used both I recommend the Tree IV over the Quik-jet.
