My soil pathogen test said I had a high level of Pythium in the soil. They recommended using metalaxly (Ridomil Gold: Subdue MAXX) to "reduce Pythium to a manageable level". Does anyone have experience with these agents?

Subdue Maxx is the original version of metalaxyl. Ridomil is off patent. Either works well.
But so do these others:
Aliette or Prodigy Signature (aluminum tris)
Banol (propamocarb)]
Heritage/Quadis (azoxystrobin)

I used all the fungicides you mentioned - this past year in an elegant sequence, tied into my fertilization and insecticide program.
Quadi(r)s is fairly new to the market and expensive.
Ridomil Gold - hard to find in small quantities.
All my $ and labor still did not defeat my fungus - I could get them to almost 50# in 10 days but they'd be flat by 14 days. This was the gardens first year and there may have been a serious imbalance of microbes that might assist keeping the fungus in check - working on that problem.
By chance did you have wood stacked where your garden is now? Still working on the problem. Good luck

Hey John...I couldn't get them past softball size...Turns out it was Fusaria...same problem go flat in days but I'm also not sure if the pumpkins were ever pollenated with the problem...they would black spot...and fuzz over....used only captan and daconil but this year going to try something harder on fungus! I did have a wood pile close to the patch that has been removed but I'm sure there is plenty of stuff buried there. Chuck

Your looking at root rot, a big problem since it spreads and kills plants. Farmers end up alot of times digging up the bad areas with high concentration, and then replacing the soil.
