Coconut Oil as Fungicide?

[Im Just Saying]

I read in an older thread while searching about mildew that that coconut oil is an natural fungicide. I noticed today that my newest phal (acquired 1 week ago) has some white on a root and a patch on the stem. It doesn't look fuzzy or slimy however I don't recall seeing it a few days before. I'm taking it home tonight to repot (it is in sphag) however I wanted to treat the affected areas as well. Can anyone chime in to the effectiveness of this as a fungicide? Does it need to be in liquid form to apply?

Hope I can get this answered quickly as I have to rush to my local nursery after work. Thanks everyone!
