Personally I leave it in place.  The kiln will kill the mold spores and the jointer/planer will remove it.

Let the machines do the work.  Kiln dry it, sterilize, then plane and edge.

I'm not a fan of the idea of filling my shop, my lungs, and dust collector with mold spores. I'd mix up a mildly diluted household bleach mixture and spray it on with a garden sprayer now.

Although you might kill the mold now by using a fungicide, the spores that have been created will still be there.  Further, if conditions are ok for future mold growth, the mold can come back unless the fungicide has a long life or time of activity.

In general, adding liquid water (with or without a chemical in the water) to the wood with a species like oak, and even in hard maple, when the wood is partly dried will make any checks a lot worse...the instant swelling of the surface when wetted will pull the checks deeper

Mold and mildew fungi grow only on the surface of wood as there is no food for the fungi inside the wood.  So, it is correct that light planing or even brushing will eliminate the fungi after drying.  Also, it is true that the kiln heat over 133 F will kill them as effectively as a fungicide.  The heat will also kill the spore, so the residue after drying is not an issue, other than dust of any type, including wood dust, can be unpleasant to many people.  In fact the fungi residue is easy to remove after drying with a stiff brush without water.
