There, your position amazes me. K is in the formula of many liquid fertilizers. It is essential for all plants. The question is that of the dosage ...
Its effectiveness against powdery mildew and some other fungi (Marsonia, Botrytis ...) is supported by multiple trials with protocol. It is, like all "non-worrying preparations", quite relative! It is approved in the vast majority of countries, Europe, Canada, USA for "organic" cultivation. It is marketed under different trademarks (Armicarb, for example).
This would be linked to the effects of drying, therefore comparable to a "burning" of the hyphae of the fungi. In this case, it is rather the salt (therefore both - bicarbonate and sodium or potassium) that would play a role. But the mechanism is not really scientifically established, to my knowledge.
It is little or not effective on fungi which "sink" very quickly into the parenchyma, such as downy mildew. I would have to verify the authorization, but I believe late blight is not on the list.
There is a risk of "burns" (as, moreover, with sulfur): the dose is 0,3 to 1%. From 2%, there are leaf burns (I actually made the mistake of overdosing - I confused a level teaspoon and a rounded teaspoon - a treatment and directly observed this effect!)
A document to download. The astredhor is a professional organization which advises horticulturalists. As such, like the services of the chambers of agriculture, he is not in the habit of talking bullshit, the responsibility being far too great. He does "field trials" on a lot of subject:

The vegetable garden without getting tired
Re: The vegetable garden without getting tired
It had been several days (weeks) that I had to harvest the chard, but laziness obliges I thought that just like the zucchini harvested previously that they would come by themselves to the kitchen, but no!
Suddenly, yesterday I decided to harvest a bunch and cook them with béchamel sauce. Too too good!
The day before yesterday I noticed a rodent attack in the leeks, so suddenly I had to take out the traps (first outing in 2021). But nothing caught yet ...

At the beginning of the week, I had a little mess in the vegetable garden, I found a hole, it seemed strange to me for a vole, but I set a trap anyway. I caught a mouse.

rodent attack in leeks,
Beautiful chard! Here half of my plants have gone to seed.
A priori mice attack. Put the traps all over your leeks with a cheese crust.

Re: The vegetable garden without getting tired
Sown or planted early ???
My first lifts, spontaneous, have almost all risen. They had suffered the cold and have vernalized.
Plants raised in early summer keep getting taller ...
The origin is the same: seeds that fell to the ground last year.

Sowing on 10/04/2021 and transplanting on 13/05/2021.

The cold snap at the end of April ????
It would be fine-tuned - staggering 10-day seedlings in 10 days.

May was no hotter than April:

Re: The vegetable garden without getting tired
Yes indeed.
I remembered the frost at the end of April, and the damage it had caused ... Arborists and winegrowers in tears ...
All this could have favored the vernalization, of which I remind you that it is not "negative temperatures" which are necessary. "Cool temperatures" around 8 ° C, at the right stage of the seedling and for enough time, may be sufficient (I'm vague because I don't have the precise data in mind) ...

For chard I do not know, but I looked for celeriac to be able to make them early at home, and remember it was temperatures below 12 ° from six leaves. It really surprised me, because it doesn't seem really fresh, and above all I put my sowing back, it was always a little early, but not that much.
