can anyone recommend a fungicide for use on Verbena seedlings ?
We bought a 'bargain' tray last week and potted them up into 3 inch individual pots. They are in a South facing cold Conservatory i.e. no artificial heat. Did not notice anything amiss when we potted up, but over last few days a white powdery 'fungus' has appeared on the tops of the leaves
thanks

I can't recommend any chemicals but you could try either of the following:
5g of bicarbonate of soda, 10g soft soap to 1 litre of water
or
1 part full cream milk to 9 parts water
Spray all effective leaves until they are well wetted. Repeat as necessary.

Georgie,
used your full cream milk method, twice over last five days, problem appears to be solved ...
many thanks

What's the ventilation like? Fungus thrives in damp stagnant air.

Robert,
plants are in a South facing cold conservatory, there are 2 side windows, double sliding doors and 4 roof vents which can all be manually opened, circulation has never been a problem. What has been hectic this last week/10 days is the variable weather/temp.
We have gone from -3C heavy frost, +3C snow on the ground, up to +12C (outside) and +25C in the conservatory, not quite all in one day but pretty close ha! ha! we have been running about like 'whirling dervishes' (well ... retired dervishes ;)) trying to keep some kind of even temperature which of course means a good air circulation.

Oh you are welcome. It was a tip I picked up from this site a couple of years back I think. ;D
