Tebuconazole

I have a bottle of a pesticide/fungicide labeled for ornamentals. It is imidacloprid as the pesticide and tebuconazole as the fungicide. It is a soil drench and works well for my roses.

Here’s what I want to do. I have some apples that were grafted last year, and I have no intention of letting them bear fruit for another two years.

Could I use this product on my apple trees, since for at least the next two years, they are ornamentals in the sense I am not letting them form any fruit and have no intention of eating anything from them?

Constantly reapplying fungicide here when it rains every other day is getting to be time-consuming and expensive. A once a month soil drench would be cheaper and easier.

Does anyone have any thoughts about this before I do it?

Greetings,
I use a fungicide product containing tebuconazole labeled for fruit trees named “TebuStar 45WSP. I’ve had excellent results over the last 3 years, losing no fruit to rot or other diseases. In reviewing most Growing Guides, Tebuconazole (formely” Elite 45WSP") is generally rated the equivalent to fenbuconazole, the active ingredient in Indar. I purchased mine on line from a grape growing supply company for a very low price.
