Cherry tree disease

Hello, I need help on a cherry branch, there are a lot of black dots on the tips of the branches. The cherries are already turning red, so I'm afraid to spray something poisonous. what can I use?

 

I can’t help re what it might be, but I wouldn’t spray anyway unless I had a definitive diagnosis.

Cherries can get a fungal disease called Cherry leaf spot and I believe you can spray to help prevent it but possibly not as a domestic gardener, but very early before the leaves open. I believe it does little damage to the actual tree or fruit production.

 

We sprayed in early spring for diseases. But, unfortunately, it still happened. Well, I'll just wait until we harvest the crops
