A camera lens can be misleading so I’m less than certain it’s what I’m seeing, but some varieties of apricots are highly susceptible to scab. I would guess Monterey Fungus Fighter might be a solution if that is the case. Indar is what I use for it.
Yes, that looks like peach scab. I use sulphur on it. This year I wanted to see if some apricots were sensitive to sulphur so I skipped the sulphur on the cots, but they are as healthy as last year. So, I don’t think there is any sensitivity problem on my varieties. I have more spotting this year since I was not using the sulphur. You need to spray at dime or so sized to abort this disease, its too late for this year.
I’m not sure how well propiconazole works on it Alan. I think chlorothalonil (fungonil for backyard growers) is the best of the synthetics?
Scott,
The Fungonil label says not to use past shuck split. Was wondering what would be the reason.
Alan,
I used Monterey two weeks ago. Had two days of rain at the start of last week and I could not get up to the orchard until today.
They got Captan & Immunox today. But we are expecting rain on again Tuesday & Wed. this coming week.

To my knowledge and experience, only the SI’s have kickback and can dry up scab after it has begun on the fruit. Chlorothalonil is good for preventing it but useless after the fungus is on the fruit. Indar, the sterol inhibitor I use, won’t clean up the fruit but will stop it from rotting before it is ripe.
