black stuff on sunflowers
« on: May 29, 2009, 23:31 »
Hi all - tried using search facility for this but didn't get anything - we're back from hol and quite a few of our sunflowers have a sooty/shiny stuff on the leaves with some distortion of the leaves too - any ideas? Have googled sunflowers+ black stuff, sooty mildew but nothing in particular...

Are there aphids - greenfly etc around?

I try to take one day at a time, but sometimes several days all attack me at once...

no sign of aphids so it's not black mould growing on the honeydew... the plants look a little sad but not unhealthy, though where the worst patch is the leaf is a bit wrinkled...

perhaps some kind of rust?

I think it's black spot. Happens on stems as well. Some of mine have got it. Does not generally have much effect on plants. Despite that I should give up now, if one doesn't get you, another one will.  :(

They say there's power in positive thought.....but don't think it works when you are sure that something nasty will happen :ohmy: :unsure:

Oh? What's going to happen? Most plant diseases don't kill most plants.

Savbo, despite the pessimism on this thread, I would keep going  :D

If the leaves drop off, remove them as good plant hygiene is a good practice.  Make sure the plant is under no more stress than it needs to be - water properly and perhaps make sure it's been fed if the soil could be depleted.
