Surround on foliage

[Fygee]

To help prevent sunburn during the Vegas summer, I'm giving a go at using Surround kaolin clay on my avocados and green portions of my mangoes.

Is it bad for the plants to have Surround on the foliage? On one my mangoes some of it got on a new cluster of leaves and they died after a week. Mature leaves seem to be okay...for now.

Thoughts?

I've used it for years in S. Texas Summers. No problem, other than it always seems to rain after I apply it! D

If you use caolin with acid water its possible it can cause aluminum toxicity .
Certain plants at various stages are more tolerant of aluminum.

We have super hard water in Vegas. Very alkaline for tap.

Guess this may be the first time that's actually been a good thing. Lol.
