Bayer 2in1 Systemic Rose&Flower:dosage+safety?

[stefpix]

Hi
I got some granules of container plant dosage Bayer 2 in1 Systemic Rose & Flower Care with .22% Imidclorprid as active ingredient.
It was on sale at Lowes and was a good deal.
I wanted to use it before taking in for the winter some orchids and plants in small containers I have outside.

Does anyone know the dosage for small and medium container sizes? The label only gives the dosage for shrubs and roses in the garden.

I have been searching the web but no indication of how many tbsp /tsp per pot.

There is a Bonide systemic that is .22% imidclorprid
Bonide
that has dosage for different pot sizes.
So I was wondering I could more or less use that dosage.

Would the slow release 6-9-6 fertilizer in the Bayer burn the roots?

There is a version with Disulfoton that I read is way more toxic so I made sure to get the version with Imidclorprid.
