Can I use this while my roses are in flower?

It is a better strategy to use the fungicide before growth starts in the spring. Spraying in summer can be done but best in the evening when it is cooler. Once the plant is sprayed it is best to not repeat the treatment for another three months. Having said that there is a risk of the foliage being burnt by the treatment if it is less than a few weeks old. If this happens the damage is usually to the tender new growth and looks like it has been touched by frost. Try to use the spray when there is no wind and avoid over use. A light application of fine a mist is best. It also helps to remove or pinch out any parts that are damaged by fungal infection before spraying. Dispose of the removed infected pieces in the houshold black bin, not in the composting. Any tools used like secateurs should be wiped down with a antibacterial agent or methylated spirits after use.

Does this contain difenoconazole, azoxystrobin, propiconazole or myclobutanil?

In response, this product contains Trifloxystrobin & Tebuconazole and none of the ai's you mentioned

Will this work for brown spot on a camelia and clamentis?

In response, Fungus Control and Protect is effective against a large number of fungal diseases, especially leaf spots. However, it is not possible to identify the disease from your description. The suggestion would be to try the product that is approved for use on all ornamentals. Please be aware that, if it works, it will stop any further infection but the existing damage will remain.

Will this control box blight?

Sorry it works well for fungus black spots but I haven’t heard of box blight.

Great for my roses

Worked to clear black spot on my rose. Luckily I caught it fast so can't comment on fixing terrible black spot but it worked for me. My rose leaves are clear and it's blooming when it wasn't before.

Guard not attached

Can't see any way of contacting the seller so - the red trigger guard was off when it arrived. Package not damaged. I can't tell whether it's damaged or unclipped. But the spray seems to work, so I'll give it a go!
