Pure Bloc turns the natural whiteness of our freshwater diatomaceous earth into a practical crop-protection tool.

On treated plant surfaces, it forms a visible white mineral film. That film helps reflect sunlight and reduce heat loading on exposed fruit and foliage, supporting sunburn and heat-stress management when used as directed.

Pure Bloc begins at the deposit that gave Pure Mountain its name. The material is naturally bright white, and its color belongs to the mineral itself.

Pure Bloc requires a different finish from the dry-use products in our line. We process it with water mixing, spray application and the even, visible coverage of a mineral particle film in mind. The result is a product prepared specifically for orchards, vineyards and other crops.
