Incredible for black spot, mildew and aphids
I have a a small enclosed patio full of plants (including 6 roses) riddled by powdery mildew, downy mildew, black spot and aphids. This year after the late winter pruning I had to prune my roses again in March due to heavy black spot.I tried many remedies, all of which effective only for a few weeks.A spray mix of horticultural soap/oil and potassium bicarbonate was the most effective but didn’t prevent this outbreak (very wet winter in London). When I added this product to the mix all the problems disappeared and beneficial insects are thriving (for the first year I have lady bugs!).Two months on and despite the rain the plants are well.The product is easy to mixIt smells a bit of sulphur when applied but it doesn’t last.As the only downside it leaves a dry milky deposit on the leaves (similar to what copper does, but white), but the benefits outweigh this.

This works!
I use this every year. Spray with a fine sprayer after pruning, fertilising and mulching in the Spring (March), then again a month later.( If you do see black spot appearing then remove leaves straight away and destroy by burning them. ) I also Spray in June then July. One pack treats my 50 roses with enoughleft for the following year. Make sure you spray underneath the leaves and stems. A fine pressure sprayer is better than a hand sprayer and makes this product go further. My roses are in excellent condition, glossy leaves, no blackspot, yellowing and blooming well.

Improved roses
Used to prevent blackspot on roses. It didn't dissappear altogether, but definitely improved the plants

Works well on large area
It doesn’t completely remove black spot initially. But it improved the health of my roses. The black spot has reduced considerably and it seems to keep the mildew off my leeks. It’s good value for money if you have a few roses and is cheaper than the pre mixed ones. So far seems a good product, it also doesn’t contain a pesticide which a lot of black spot products do, so it’s been helpful in not knocking out my natural predators.Very happy with this product.

Start early! Roses & hollyhocks.
Bought this for my huge climbing rose which was very badly affected in 2016 by blackspot. Unfortunately I didn't buy it early enough to dress the ground or spray before the new leaves were fully emerged. However, I've given the rose an occasional spraying and the blackspot is much reduced from last year. I appreciate that diseases of roses are linked to variety of rose and location, and must admit my climber is not in a good location. I feel the product has done a good job in difficult circumstances and enabled me to have a lovely display of Madam Henri Carrier.As this product can be used against rust on hollyhocks I used it on mine which had severe rust last year. This year's hollyhocks (in same spot as previous years) have been fairly clear of rust and still have a good amount of healthy leaves.
