Sunflowers, dirt, stone and sand cannot block the corruption in hard mode. Anything else such as raw ore, or building material such as any form of brick can stop it. By building a 4-5 block width wall into the ground (not around stone as it can pass through stone around the wall) Where as with dirt, it can only travel 1 dirt block inwards creating more corrupt grass or onto dirt that has a free leading space (no block connecting to that part of dirt block)
