How often can I foliar spray Potassium Silicate?

If you knew botrytis or PM spores were in your garden and got a bottle of potassium silicate, how often would you spray?

I'm playing catch-up to prevent an outbreak but I don't know what would be considered too frequent of applications. Most people / companies say once a week but I've already done two applications spaced out by 2 days and there have been no visible problems with this. No phytotoxicity or anything funky.

Any thoughts?

You should be fine but once a week is likely good enough. Spraying more isn't necessarily provide better results and could possibly lead to issues if you keep spraying every 2 days. I use it myself but I start spraying about once a week in the spring. I spray everything in my yard. Since I've been using it as a foliar I haven't had PM on anything in a couple years. I also add a little sesame oil. Sesame oil is the active ingredient in Organicide 3 in 1 garden spray.

Awesome, appreciate the response. I unfortunately didn't find out about it until last week. Do you use the sesame oil in flower too?

Botrytis and PM spores are all around me

I try to choose strains that are resistant and also try to avoid subjecting them to conditions that encourage mold/fungal growth
