need anti-fungal concentration of copper Sulfate

[Peter O'Brien]

My sunroof leaked for the entire summer, and now I have a nice bouquet of
fungal flora sprouting under my floor mats.  I recall that CuSO4 can be
used as an antifungal on plants, and want to try to use it to deflower my
carpets.  Does anyone have a suggestion or reference as to the minimum
necessary concentration for the antifungal activity of this solution? 

 Please reply by e-mail after removing the spamproofing phrase from my
