CULT: ROT: Historical note

The subject of rot toggled my memory of reading something about it in an 
uncle's Iris notes.

So I checked, and offer the following for historical interest.   
Geographical location was Lynbrook, NY.

(I'm new at this, only having my first blooms this year from inherited 
rhizomes, so cannot offer anything from my own experience.  But, whether 
it be Dial, Clorox or whatever, in this era of gaining antibiotic 
resistance, I haven't noted anyone suggesting scooping out the soil 
around the rhizome as an aid.)
 

Extracted from Howard R. Glutzbeck's "Notes of 1933":

===== BEGIN QUOTED TEXT =====
It was noticed about Sept. 1st that iris rot was gaining a big foot among 
the seedlings undoubtly due to the continuous wet humid weather and also 
the wild cherry tree shading the bed, and preventing the ground from 
drying out on the sun shining days.  Trot also developed among the stud 
but was checked and controlled by the following methods -

When an affected plant was discovered, often the condition of the leaves 
told the story, the ground around the rhizome was carefully scooped out 
leaving a depression.  then the base of the rhizome was examined for the 
infection.  All rot was carefully scooped out and with aid of a small 
insect duster "Cupro-Jabonite" was blown into all the cleaned parts that 
had been affected by the rot.  The depression in the soil was not filled 
in as it was believed that the sun and wind would help matters too.  This 
turned out to be correct.

In a few cases just the soil was removed around the rhizome and the rot 
scraped out - no antiseptic applied.  This worked too.

In cases where the rot had gained such a headway that the main fan was 
rotted away, this was removed.  Decayed part scraped out and well dusted 
with "Cupro-Jabonite".  Drainage cuts made in this depression to avoid 
the collection of water.  This was done to save the side fans and in 
nearly every case proved successful.

Altho in this latter case there will be no blooms in 1934 but the 
seedlings was not lost and will undoubtably bloom in 1935.

At the time of this writing the rot seem to be well controlled.

Note #53-2 (Neen x Wm R. Dykes) was one of those seedlings;  one of it's 
progeny was subsequently crossed to become "Spun Gold".
