To pull (mine/take) Corrupted Dirt, you will need to equip either a Diamond Mining Cell or Lumite Mining Cell. Alternatively you can also "purify" Corrupted Dirt by placing a Healing Beacon close enough or by throwing Purification Bombs and turn Corrupted Dirt into simple plain Dirt blocks by that. These can easily be mined with basic Excavators then. Currupted Dirt can be made by throwing Corrupt Bombs at ordinary Dirt blocks - while Rocky Dirt or Brown Mushrooms will stay unfaced by that and Grass blocks will turn into Corrupted Grass.
