Hi Mark, I did a lot of chasing around last spring trying to get hold of Prosaro to treat a smut - Prosaro is a mixture of tebuconazole and prothioconazole and is also labeled for Stagonospora sp. I found the Prosaro at a crop protection services (http://www.cpsagu.com/map/Default.aspx) place about an hour away - but it is sold in 2.5 gallon jugs for well north of $1000 - for crop spraying. Crop protection Services seems to have a lot of locations in eastern NC. I paid them a visit and chatted to the manager and he very kindly gave me a couple of pints in exchange for a look around my garden. In the meantime I'd also contacted Bayer, the manufacturer, and after about 3 weeks got a call from the local rep - who was also very understanding and shipped me a few more pints - also free of charge! I'm good with Prosaro now for a few years but - to get to the helpful part - the crop protection place also sold tebuconazole - and 2.5 gallons was well less than $200. The prothioconazole is the on-patent component which massively jacks the price up, although it is excellent because although the two compounds are of a similar class, they have different modes of action and therefore chances of resistance are much lower.
