Soybean Rust! (Geeky Fungicide Question)
This invasive species, new to the Americas in 2004, is hosted by legumes and kudzu, travels long distances by wind, and has moved into my garden for a second year! Also, Maryland did not have a good hard freeze this winter to kill off last year's spores.
The rust starts at the bottom of the plant and moves up. At first it is hardly noticeable and may look like dirt splattered on the leaves from rain.
DISEASE: Soybean Rust
PATHOGEN: Phakopsora pachyrhizi and P. meibomiae
HOSTS: Soybean and kudzu are the most important hosts, but there are over 90 other hosts known for P. pachyrhizi. (Mostly legumes, but as anyone south of Mason-Dixon Line (an hour north of my home) knows, the South abounds in soybeans and KUDZU! -- talk about an invasive species!)
http://www.apsnet.org/edcenter/intropp/lessons/fungi/Basidiomycetes/Pages/SoybeanRust.aspx
It seems that the following are the recommended fungicides. I cannot find them by these names for the home gardener -- does anyone know if they are available?
Trade names, examples Active Ingredient Manufacturer/Marketer
Abound™ 2.08F, Amistar™,
Heritage™, Quadris™ azoxystrobin Syngenta
Reason™ 500SC fenamidone Bayer
Disarm™ 480SC,
Evito™ 480SC fluoxastrobin Arysta
Sovran™ 50WG kresoxim methyl Cheminova
Cabrio™ 20EG,
Headline™ 2.08EC,
\Insignia™ 20WG, pyraclostrobin BASF
Compass™ 50WG,
Flint™ 50WG,
Gem™ 500SC trifloxystrobin Bayer
Table 1. QoI fungicides commercially available or expected to be available soon in the U.S. (Updated 2012)

Re: Soybean Rust! (Geeky Fungicide Question)
Maybe this will help.
I tried to find more information about the disease, but it seems that it's still an ongoing research thing. Usually if you don't grown any host plants for X number of years, the spores will die. Not being able to find that information is annoying at best since I dislike using biocides.
