@marknmt ,
The link you post in post# 9 did not work.

@JohnLivo , most if not all spray amount should be in this link. It is under Guide Category.
Spray amounts guide.

As for less toxic chemicals, please check out this link.
Low-Impact Spray Schedule (2019 Edition).

Also under Guide Category.

Reading these two links, it will answer a lot of your questions.
