Wollammo!™ Prevent and Eliminate  Powdery Mildew and Promotes Healthy Cell Growth

Wollastonite will prevent and helps eliminate powdery mildew while  promoting  healthy cell growth.

Wollammo!’s high quality wollastonite has been shown to be beneficial to plants in a variety of ways. Most notably, in our research trials powdery mildew was virtually undetectable with wollastonite admixture above 10%.

An admixture above 10% wollastonite also correlated with sharp reductions in the presence of thrips and fungus gnats, insect pests with a sub-soil life phase in which the wollastonite crystals lacerate and impale their soft bodies. At a microscopic level, wollastonite’s needle-like structure penetrates soft-bodied insect larvae and pupae, interrupting the life cycle without the use of pesticides.

Wollammo!™ has unique properties that allow it to break down into calcium, magnesium and silicate in a highly bio-available form that balances soil PH throughout the growth cycle. This allows the plants to uptake silicic acid and promotes strong cell walls that better resist insect feeding and spore penetration. This also supports increased plant growth and elevated product yields.

Wollastonite (CaSiO3) is an extremely useful calcium-silicate mineral mined in St-Onge, Quebec. This rarely-occuring earth mineral is only found in in a few places worldwide.

Wollastonite has a wide range of uses thanks to its unique organic makeup. For agricultural use, it provides a source of plant-available silicate, carbon neutral calcium, and magnesium as well as many other beneficial trace elements and micro-nutrients.
