A notable lack of this phenomenon is caused by the deficit of one element in the soils around Walla Walla, Washington and Vidalia, Georgia. For 10 points each:
[10h] Identify this phenomenon, which is caused by the chemical syn-propanethial-S-oxide after it is produced by LFS. A description is acceptable.
