sooty mould.......

Hi All,

I have had to spend all day removing loads of the foliage on some of the furry leaved wildflowers in the garden because they were full of grey mould. I presume ( perhaps incorrectly) this is to do with the dry spring we have had ( other than of course the last few days). Looks like a visit to Wilkos for some sulphur is in order. Anyone else had this?

 

Grey mould or sooty mould Lolli, two very different problems.

Sooty mould is usually caused by secretions of pests such as aphids or scale insect.

 

Sorry, I wasn't thinking properly when I posted the title. It isn't the black stuff.


Lots of little spots of dusty pale gray mould-very disfiguring and disheartening considering I have spent the early part of spring watching these little flowers grow up.


Bit concerned about some of the furry leaved foxgloves to be honest-nothing on them yet but................



edit-should have taken a pic or two before binning it all.

 

Mildew perhaps?

 

I would say so, am I right that the mildew on one plant is different to others- ie if I have it on forget me nots and dead nettles, the foxgloves and phloxes won't be affected?


Any good cures you have come across Pete?

 

I don't know anything about it, but I seem to remember I have often seen it towards the end of the "season" for Forget-me-nots and so on?? Is it a normal sort of a thing?

Courgettes too ...

 

No, I haven't ever had this happen before whilst I have had forget me nots that is, and the red dead nettle have it. There is/was loads of it.

 

"I presume ( perhaps incorrectly) this is to do with the dry spring we have had"

I would have thought that damp would bring the moulds on more, but maybe we have had enough moisture, AND warmth?

Spray with a fungicide to keep anything at bay and prevent reinfecting?

 

It's my only option.

But not having had this problem here bfore I am at a loss as to which one to use. I will probably settle with sulphur.

 

I'd just use a normal fungicide that says it works on mildew.

I have a feeling that mildew tends to strike when plants are dry at the roots, and not making much new growth.
Thats why it tends to be common at the late part of the season on container plants.

"Nimrod T" was the buisness on mildew, but I dont think you can get it now.:(

 

I tend to spray Holy hocks and foxgloves etc at the same time as roses. At the moment Im Using Nimrod, they probably have banned it now but as Ive got a 1 litre bottle....... !!!!!

I rekon sulphur should work fine.

 

Lollipop,Nimrod T is not a product to be used in these enlightened days and I'd not recommended it's use.

If this link is anything to go by I dread to think the harm it does to the environment.

 

Must be one of those things that we can build bombs from or something-I don't know.



Because of the sort of slapdash technique I tend to have have I can't be trusted with pesticides or herbicides, I reckon I can't do much harm with a liberal dosage of sulphur though.

 

Paul are you referring to the sprayable sulphur that you directed me to some months ago?

The one for roses

 

Yes Pete.
