Found several of these spots on the trunk of a young mulberry tree, anyone know what causes this? Could this be sunburn or frost/freeze damage?
I’ll also add that it did leaf out and the unfurling leaves got zapped by a bit of cold a few weeks ago

Knowing where you live would help, but it could be a Cobalt Milkweed Beetle if you live out west.
I live in SE Michigan
When I get damage like that on figs it is usually cold damaged buds letting Grey Mold get started. I’d draw around the border of the dead spots with marker to see if it gets bigger.

Perhaps a Grape Flea Beetle? Bud swell is time to monitor vineyards for cutworms and flea beetles - MSU Extension
Flea beetle in general is a good possibility; where on the property are you seeing most of these beetles?
They are pretty much all over the yard but haven’t noticed them on buds at all. Going out now to check the buds on grapes.
Searched for 2 hours, but can’t truly match the problem on this tomato plant. Not TMV (the problem goes from leaf margins or spots, not from center of leaf), and the color doesn’t seem right for early blight or septoria. Ideas? Grafted Early Girl with resistances listed on plant tag. I can run out and take more photos if needed. The tan spots aren’t soft, but rather the leaf gets brittle where it’s browned. Problems are working from bottom of plant upward.
Four-spotted sap beetle / Picnic beetle (Glischrochilus quadrisignatus)
Not a good thing to have but probably not too problematic since they mostly feed on damaged or overripe fruit & vegetables. If they are a problem, then good sanitation and bait traps are the best solutions. They love anything fermented.

I came across this today. Would anyone have any comment on whether it will work?
Thanks TJ and Braddy for your help identifying this bug
Found this on my plum scaffold today…its been a super dry spring to this point looks like sap (clear in colour) is building pressure and is splitting bark open to relieve the pressure? Leafs all look good, only happening to one scaffold any thoughts?
Its coming out of intact bark with pressure bubbles/splits not at site of old or new pruning cuts
asymptomatic gummosis, I would just keep up a regular fungicide spary plan.

Scarlet Malachite Beetle (Malachius aeneus)
Good bug. Adults eat other insects and pollen. Larvae prey on soft-bodied invertebrates like grubs and aphids.
