Glyphosate Impact on Disease? the need for Manganese??

The short answer is no glyphosate and or RR varieties do not impact disease severity and no again it does not impact your fertility management between non RR and RR varities. The long answer is it depends on your soils, the pH of your soil(high pH soils so that excludes most of you) .  One really needs to review some key basics.  Dr. Bill Curran sent a nice set of links to discuss the issues surrounding some claims that with Soybeans growers should add Manganese and or that diseases may increase.  There are three articles you need to familiarize yourself with to be knowledgeable about whether Managanese applications are useful. Some farmers might find they may have an issue. It appears that the majority of farms will most likely not see any impact.
