Rose buds not forming well

Looks like my Roses are poorly, lots of buds and flower but some do not open and bloom well. Does these pictures reveal anything.

    Most of mine look like that just now - but in my place it's because they've had three days practically non-stop rain as soon as the buds on my late flowerers and the buds on my second-flush roses had nicely swelled up and were about to start opening.

    Balling. It can happen with peonies too. Dianthus can also get a bit manky with rain too, mostly the doubles. 
    The buds get a bit stuck due to weather, when they don't have quite enough oomph to open properly, although it can also be down to the honeydew secreted by aphids, especially with ants farming them, causing petals to stick, as someone on the forum informed us earlier this year.  I expect that can happen with roses too, as they often get targeted by aphids.

    What can I do to prevent this happening, I'm using a 'Rose Clear' bug gun which should take care of Aphids etc but the spray gun states 4 times per year is max treatment.

    Apologies @len-tikular. I was looking at the bud in the 2nd pic which was reminiscent of the issue with peonies.  :)
    I freely admit I know next to nothing about roses.  :)

    ..sprays are no good, there isn't much you can do about it, as we live in a generally humid climate and this affects roses and other plants at certain times of the season, more than others..
    ..it's a common fungus, you can't get rid of it..

    Some things you can do..
    ...reduce the humidity around plants by providing good air circulation, reducing ground cover, deadhead any infected flowers  and dispose of fallen leaves and petals; and generally maintain good garden sanitation.  I find mulching is good.. 

    ... not all roses are affected that much, I have some 70 roses and hardly notice it on most, and if it's there I largely ignore it, but if I have a rose that continually suffers from it, and spends too much time looking unsightly, then I will get rid of the rose... simple as that.. and replace with another, that will be less susceptible...  trial and error on that usually..

    ...really not worth worrying about it too much.. 
    ..try and adopt a more relaxed attitude to gardening with roses.. none, and I mean none, are perfect..
