So, I was sitting around thinking, why don't the microbes die when they are sprayed??? My sprayer pumps like 30psi and about 30 feet so I am wondering how these little microbes aren't killed during the spraying process.

sdreefers,

Good question, and to be totally fair, some microbial loss is unavoidable. The bacteria will survive almost anything, but the fungi and protozoa are a bit more sensitive.

The only way to know for sure is to use a sprayer that's already been tested, or take a look at the tea under a microscope before and after it's been through the sprayer.

In order to minimize damage, many people use sump pumps, or pumps designed to allow larger particulate. In addition, a nozzle tip that has no right angles, lower psi, larger droplet size and more of a rainbow effect when spraying.

I like to use a watering can with a fine nozzle. A thrifty drench!
