Which? recommends Bayer rose blackspot products

Two Bayer Garden products have been recommended by Which? Gardening for tackling blackspot on roses: Multirose² Ready to Use and Systhane Fungus Fighter.

Blackspot is caused by a fungus that over winters among fallen leaves or in dormant infections on young stems and buds. Infected roses exhibit 'black spots' on the leaves that then turn yellow and drop off, with the plant eventually dying. The destructive infection is difficult to fight because the spores travel in the air.

Which? Gardening trialled the products by first infecting 'Silver Jubilee' roses, a modern variety that is more resistant to blackspot than older varieties, and then surrounding them by the more susceptible 'Frensham' roses. Treatment was started at the first sign of an infection.

Bayer Gardeen product manager Alison Mulvaney said:

"We're delighted to have been 'Recommended' by Which? Gardening for two of our products. Our philosophy is 'science for a better life' and innovation is our constant; we are always seeking to develop products that tackle the challenges gardeners face with minimal environmental impact. It is this approach that directs our product development strategy, each new product taking six to ten years and about €260 million to develop, trial and bring to market.

"At the end of this process we are able to bring to market highly effective products the help gardeners tackle tough problems like blackspot. By giving our products a 'Recommended', Which? Gardening has agreed that in this instance our approach has worked."
