moldy crud on sepals
 

Oh no... having a pretty nice sunny day today and then I found this crud on sepals of small fruit, two plants one cluster each affected... It looks to me like grey mold or similar getting started on the place where aphids had been feeding. :(
I was going to ask advice first but then I panicked, being a very windy day as well with all vents open and quite a gale blowing through the greenhouse, so I dabbed the surface with a little peroxide and then pre-emptively removed fruit and or affected sepals.

What would you do?

And the other one:

Oh good grief! Now what, :?::evil:
Looks a bit like insect crud. Is it sticky or flaky? Crusty?
I also see tiny black dots on the stems...

I get that on my fruit trees at the same spot but never on tomatoes.
I wrap duct tape sticky side out about a foot wide on the trunks.

Yeh... gross. Spent the whole morning pruning to make sure there's air circulating around those fruit... Killed a few ants and yes I found still more aphids throughout. :bummer::cry: It's really bad.
I was expecting a guy to come in March or April and fix the window in which sill there is a nest of ants, but other work came up and I guess I fell to the bottom of his list. :evil:
Maybe I should do sticky tape around tomato stems? :?!?:
As for the crud, some bits were just like a dry damaged leaf, but there was also some visible grey mold - just enough humidity for that on a sunny day. Today is even more humid, so no regrets about sacrificing the affected fruit... that stuff spreads fast if you don't pinch it!

Re: black spots - I think those are just the usual tomato glands (which should be full of ahem aphid killing goodies - huh?) - but I will take a second look.
