Do sunflowers get blight?

[glallotments]

I've just picked aome sunflowers from our plot and some of the leaves have blackish brown patches which look just like blight. Anyone know if sunflowers can succumb to blight?

I have never seen blight on sunflowers, or Jerusalem Artichokes.

Dear GA,
they probably have powdery mildew.

The answer is no and yes!
If by "blight" you mean Phytophthora infestans (potato/tomato blight), the answer is No.

On the other hand, if you are seeing something like this

it could be a fungal attack by something like Alternaria helianthi.

For a full (?) list of sunflower diseases there's one here. EEEEK

And good morning to you Alan - an early start?
Sally - It's definitely not any sort of mildew and does look more like Alan's photo but in larger patches - I'll check out the link. I never knew sunflowers were so prone to disease.

The flowers are OK so I can still bring a bit of sunshine inside!
