Rose Clear/Rose Clear 2 has been withdrawn (due to banned? chemicals) and replaced by Rose Clear Ultra - so make sure you're not using old stock.
RCU is an insecticide so it's harmful in that it is killing off potential food supply. And the active ingredient acetamiprid is a neonicotinoid - implicated in the decline of the bee population.

Rose Clear Ultra contains acetimiprid and triticonazole. The first is a synthetic neo nicotinoid, the second a fungicide - the second ingredient is more dangerous to birds than the first. Generally though, unless you let the birds actually drink the solution, or spray them directly with it, or spray their feed (peanuts, fat balls, whatever you might feed them with) directly with it, or use it in a room which has a caged bird within, it's not something to worry about too much. I'd worry more about bees - don't spray open flowers, and always spray at dusk, when the bees have stopped working, and preferably only use the product (or any insecticide) when essential. Pesticides and fungicides will inevitably affect the environment to some extent, particularly those used in soil.

Imidaproclid and thiamethoxam, both neo nicotinoids, were both temporarily withdrawn in the EU from 2013 for a total of two years to see what the effect (if any) was on the bee population. Any products people had containing these were legal to use up until November, 2013 only. These may be reintroduced for use at a later date, depending on results.

Thanks for that info Urbanite/Bamboo. I wouldn't want to harm the birds, but at the same time want my roses to look good. I'll try and keep it down to a minimum.
Urbanite just for the record it's new stock RCU.

But will your roses still look good when there's no bees left? I will 'fess up - I used RCU once last year on a rose that had bad mildew after being buried under builders' rubble for months. It didn't touch the mildew, couldn't bring myself to spray a second time and I ended up cutting the rose right back at completely the wrong time of year. Gave it a good mulch this spring and it has bounced back to health.

Well I spray roses with Roseclear every fortnight from April through August. Luckily most of the gardens I now tend do not have roses - managed to eradicate most of them over the years, I can't stand 'em, far too much maintenance, all that spraying, feeding, deadheading and pruning, not to mention getting stabbed by the thorns. I don't mind the occasional one, but really, they are such a bunch of disease prone things, they've either got black spot or mildew, and aphids love 'em too.

Well, I have to say Bamboo, as a complete amateur my roses are looking exceptionally well this year. A lot of my roses are not susceptible to disease. I know they can be a pain in the butt (I let the wife look after the thorny ones) lol. Having said that I am now retired so I have all the time in the world to look after them, I quite enjoy the challenge.
Watch this space next year I will probably have to eat my words and tell you I've dug them all up.

Treetop, I'll confess there is a rose I particularly like, and which I bought twice in different houses for myself - its Korresia, a small, yellow flowered fragrant rose, very disease resistant, never had a moment's trouble with it apart from aphids. But for customers, they like low maintenance, and so do I - and you can say a lot of things about having lots of roses, but low maintenance wouldn't be on the list!

If you've the time to care for them yourself, and you love 'em, no reason why you shouldn't have them.Some of the flowers are beautiful, and I particularly like fragrant ones.

Thanks for that Bamboo, I'll definitely check it out.
