250grm pack

Bought with the spray bottle so I can use repeatedly, it is great for blackspot.

Does what it says on the tin,

Very little mildew or black spot on my rises this year, such a difference. The one thing you absolutely must do is to start spraying before the leaves start appearing - seems a bit strange spraying stalls but it works. I spray every couple of weeks. Dilute the powder in a hand spray and it lasts for months.

This product has good instructions and seems to do as I hoped.

Would have preferred a liquid one but this mixed well and has been sprayed on so time will tell as to whether it has worked or not

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.

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.

Does what it says in the box.
