I'm 99 per cent sure that my pyracantha is suffering from scab. Has anyone found a fungicide that is effective? I understand that many of them have no effect.

Scab on Pyracanthas? Can you give us a quick peek of your scab please?

Sorry, all evidence removed and burnt: main symptoms: berries which form but the majority turn brown/black. Some defoliation. Symptoms not "sudden" enough to be fireblight. I read somewhere that a fungicide has to contain a certain ingredient to be effective against pyracantha scab, but I can't remember what it was! Am hoping someone will know....

Yes there is a fungicide for,pyracantha scab. You seem to,have done all the right things.

Amy pears nearby?  Pears and pyracantha suffer the same scab so need to be kept well apart.

Jusf checked out that fmgicide....the chemical ingredient is myclobutanil and apparently there are a number of sprays on the market

Wow, scab on pyracantha. Something new to add to my list of things to worry about.

Thanks, Verdun. That is just the info. I wanted. I will now be able to identify the most effective fungicide. Thanks again. P.S. No, no pears - one less worry!
