Brexil Ca + B, which is carried by Helena Chemicals.  If you are not in the trade....

There are several other similar products at other suppliers.

I'd like to try the boron and calcium.  Any recommended product I can purchase?  Thank you.

I use Solubor as a foliar spray on grapevines & a soil drench on stuff like cados and mangos.  Less is more regarding B.  Most plant foods contain B.

Depending on your soil profile Ca can be applied via gypsum or lime.

What I recommended is specifically to spray on OPEN mango bloom.

Our baby mango plants have been doing great up until recently. Is this anthracnose, BBS, powdery mildew or some other form of disease? Can it be treated or no? What is our best course of action in this situation?
Thanks guys!

This is powdery mildew damage.  Copper sprays can suppress the spread of powdery mildew and anthracnose, etc.

If you have a sprayer with a very good jet agitator inside the tank, you can spray elemental Sulfur--- only in cool weather.

Perhaps some of the live, biological sprays would work, but I have never tried those;  I assume they won't work if the trees have been sprayed with Copper in the last month or two, so it is either/or.

Thanks Har. Any particular spray you can suggest? Or perhaps post a link to a good product?
Thank you
