Sil-Matrix on Mango?

[HIfarm]

I was just wondering if anyone has tried Sil-Matrix on mango for fungus control.  I saw some on sale (or clearance?) at my local co-op & saw it was listed as a fungicide, miticide, & insecticide.  I didn't have time to look it over too well as I saw it at the check out but I picked it up anyway (2 1/2 gal for $25 sounded like a deal).  I have had time to now check it more & see it is a soluble silica and it is primarily effective against powdery mildew. I was hoping it might also have some activity against anthracnose but that is not claimed on the label.

Has anyone tried this product on mango?  If so, verdict on effectiveness?

Thanks,
John

Effectiveness against powdery mildew is reason enough to have it, but Potassium Silicate products also harden leaf surfaces against temperature extremes, wind and drought, and against chewing or penetration by insects or germinating fungal spores;  silicates also stiffen branches.

Thanks, Har, I'll have to give it a try.
