What time of day to spray for mites?

Im spraying grandivo, non oil for mites.
Im old and my garden is lots of work so i cant find an ideal time.

5am to 6:30 it gets sun before i can finish.
7pm no direct sun but its 90f still.
9pm im so tired

What temps is safe i hear 85f and below.
I hear humidity is best.
I hear night so leafs stay wet.

If i get up at 5am im unable to finish before sun hits them.

I was told direct sun will cook the leaf but even 6am?
Im considering 9pm to 10:30 its below 85f but pitch black.

Or i could spray until conditions are harsh then stop and start the next time its dark?

Spraying just before light out is probably best.

Like a few minutes before lights out.

It gives the plants all night to dry off.

Its outside. Ill hire a friend to help or half half.

Do you have a fogger?

Don't leave them wet, that's asking for botrytis

As early as possible and preferably with a breeze after spraying to dry out

You don't have to do the whole lot at once, spread it over a couple of days and you'll be fine
