What's New

In this study, calcium, potassium, and sodium silicate are tested against a common synthetic fungicide for black root rot disease suppression in strawberries. The short story is calcium and potassium silicates are tied in the end for effectiveness, and each achieves an equal or greater resistance in the infected strawberry plants tested against the synthetic fungicide. But granted the high pH of potassium silicate (and higher cost) we declare calcium silicate the winner!

Why do we think calcium silicates are the best?  CW Grow is a calcium silicate mineral called wollastonite and when compared with potassium silicate, wollastonite is easier to use and safer for you and the environment.

The researchers also found that all of the silicates improved the immune system of the plant which confirms again that silicon works at both the physical level, re-enforcing cell walls to make the spreading of fungal diseases from cell to cell more difficult, as well as increasing the strength of the plant’s immune system to fungal and bacterial diseases.
