What is edema in plants?
Oedema is a physiological disorder that develops when roots take up water faster than it can be used by the plant or transpired through the leaves. Water pressure builds up in the internal cells of the leaves causing them to burst, leaving dead cells that are visible as a blister, primarily on the undersides of leaves.

What is a good fungicide for geraniums?
Immediately treat all of the geraniums with a fungicide such as Camelot O, Compass, Daconil, Disarm O, Eagle, Heritage, Spectro, Strike, Pageant Intrinsic, Phyton, Protect or Terraguard. Repeat this sequence on a weekly basis, rotating modes of action (MOAs) to avoid resistance, until pustules are no longer appearing.
