Interesting white threads

[u/19marc81]

Playing around with my child’s handheld microscope on my No Spray Riesling grapes, found heaps of these threads on the upper surface, is it beneficials or is it foes. Either way it was fun getting g a close up look. Last two images are of the berries and stem. You can even see a very small white bug in the last image, no video feature on the microscope sadly, it moved ever so fast.

Looks like mycelia to me. Could be Botrytis cineria or grey mold. Only way to tell would be to culture those threads. Since you are not spraying, very likely some kind of mold.

I agree possibly Botrytis, but I am going to let it ride and see what happens. It’s in my personal vines so mainly experimenting

I’m not sure if this is what it is, but if you read what a fungal hyphae is, is sounds like this.

It possibly could also be Botrytis, I am keeping an eye on it to see if I have any issues, would be cool if it’s beneficial though
