Hi all,
Noticed this the morning on one of my 'Sancerre' bulbs (planted this year) - the photo shows it more than the naked eye:
It reminded me a lot of the first post in this thread -
The thread "Tulip Color Breaking Virus?" in
Lilies forum - especially once I noticed that the top didn't look quite as orderly as the others. It is the shorter of two stems from a double-nosed bulb (the taller one is behind it), so I checked the other stem for symptoms.
Edit: Four bulbs in this pot - two 'Corsica' and two 'Sancerre'. The side of the pot away from the camera was two 'Sancerre' (one double-nosed); closest to the camera was two 'Corsica'. I will need to confirm if the left most pair are double-nosed 'Corsica', or a 'Sancerre' and 'Corsica' in close proximity. The tallest pair are definitely the double-nosed 'Sancerre'.
Having seen this, I checked my other bulbs and found faint patterning on 'Navarra' (also planted this year; behind it is a healthy 'Tresor'):
None of these pots have been sitting out in the rain and I've been using Richgro's Beat-a-Bug (Natural Insect Spray) to try to keep insects off them, although I have seen a number of small black insects flying around (no aphids or thrips on the liliums, though - the aphids have been confined to the roses on the opposite side of the house and I have been effectively controlling them with Beat-a-Bug).
At this stage I am planning to isolate the pots (easier said than done, since space is limited), although I strongly suspect 'Sancerre' is showing virus symptoms. Unfortunately both 'Navarra' and 'Sancerre' are white, so colour-blotching may be hard to identify in the blooms!
