Is there a chemical / solution we could spray on our shoes / boat that would kill this binger of doom? Although I'm shocked the stench alone of our river gear doesn't do the trick!

If you click on the link to the govt. page on one of the posts you find the answer to your question. Amazing how this interweb works.
Anglers and other recreational users of Gunpowder Falls and surrounding waters are especially urged to make sure they don’t contribute to the spread of Didymo or any other aquatic invasive species. The public is asked to clean anything that comes into contact with stream water by scrubbing away all dirt and debris before leaving a stream. At home, disinfect equipment by soaking in a 5% salt solution (1 lb/ 5 gal) for several minutes, or scrub well with dish detergent and rinse well. If disinfection is not possible, let equipment dry completely for at least 48 hours. Anglers may want to consider having two sets of equipment in order to move safely from one spot to another.
From another page:
Anglers need to take the following precautions to avoid spreading Didymo:
· Before leaving the river, remove all plants and algae from shoes, waders, life vests, boat hulls, trailers
· Treat equipment with a 2% bleach solution or a 5% salt solution or dishwashing detergent
