Experiment against fungus and insects ? [botany]

[Externet]

Good day.

I was reading about a "Bordeaux mixture" for prevention of fungus and damaging insects for plants and trees.  It is a simple water solution to spray hydrated lime + liquid soap,  supposed to not deterr/harm pollinators if applied before blooming.

What is your opinion instead of spraying such mixture; spraying only the liquid soap onto foliage and branches to make a sticky layer and dusting windward with the hydrated lime powder after with the hope of hydrated lime sticking better to the plants (until next rain ?)  -Or, a better approach you may have heard of- ?

That's not Bordeaux Mixture. The key ingredient in Bx Mixture is copper, in the form of copper sulphate. As far as I know it is a fungicide. I have not heard of it being used as an  insecticide. https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/bordeaux-mixture
