I saw that J Fisher from OL had suggested Erythromycin or sulfa drugs for axial rots in phrags, so I did an internet searh on "plant antibiotics" and came up with PlantMedia [email protected]
I talked to Dr. Walhi (strong Indian accent, guessing at the spelling), who was quite familiar with Erwinia. Most intriguing was the life history acount, that orchids during the fast growth season (spring /summer) produce a lysing enzyme at the leaf axials to allow the new growth to get through. This produces a favourable environment for erwinia, and it cues in on this enzyme production.
I guess this environment is also low in oxygen since it smells like erwinia is a fermenter. So good airflow is crucial.
Dr Wally's first antibiotic choice would be Timentin if it wasn't so expensive, and has a huge order backlog, otherwise Carbenicillin and Cefotaxime were his next best choices. 5gr quantities should cover use on several plants, and the price was in the $50 to $60 range in this quantity.
