When 5 grams of FUMIDIL-B is used to a gallon , this amount is only 20%
of the bottle contents of 25 g, and will only contain 0.1 grams (=100
mg) of fumagillin. This is exactly the same dose as you get in using the
bottle of 25 g (with 500 mg of fumagillin) to 5 gallons.

No, you are not; Fumidil-B is not only fumagillin
but also some other stuffs needed for the preparation.
