None of the info I have suggest they were attempting to address Erwinia 
specificly though they may have done so inadvertantly. A portion of Morrison 
project, or a extension of it, examined the effects of the suberization 
Walter had mentioned earlier on several factors of growth and flowering in 
irises when planted at different times of the year.

Irises were dug, suberized for a 2 week period, soaked in a commecial 
fungicide, dried, and then planted. As was a freshly dug group soaked as a 
control. This was done in several months.

FYI: To date, drying of rhizomes (suberization) had been the most effective 
treatment for bacterial soft rot here. Though, a drying period of more than 
two weeks is required to be effective. Over 90% of the irises that do die 
here, do so from soft rot.

Comparing the mean temperature in the area to the recorded deaths for 
different months in which the rhizomes were planted to an Erwinia Growth vs. 
Temperature profile might yield some inferences of value.
