Ive come across a handful of publications and online sources offering credit to both these men for "solving" phylloxera. Does anyone one have a clear/accurate picture of what these two contributed to solving the epidemic?
Hi Troy. Riley was the entomologist who is credited with realizing the American rootstocks were resistant to Phylloxera. Munson was a horticulturist in Texas who had a nursery/vineyard of native vine species on land in hill country with a very high limestone content and was instrumental in identifying the rootstocks best suited to the conditions in French vineyards - a project he undertook with a commission from Cognac. Texas and Missouri coming up big to save European wine!
Here is a good book on the topic. Pretty detailed description of the whole history.
