What's the different between Yates Copper and Yates Lime Sulphur for fungal problems on roses and fruit trees

I have bought both products but would really like to understand the difference. My roses are falling victim to die back. I want to control this when I prune but not sure which one is more effective. Can I use this on my pruners to ensure I don't transmit it from one bush to another?

Hi Tina,

Now that it is winter and your fruit trees and roses will need pruning and some tidying up, this is the time to spray your plants with lime sulfur. The lime sulfur can be sprayed on the leafless stems which will clean up any diseases or pest that tend to over-winter on the plants. Spraying the soil underneath the rose bushes will help to control fungal spores and rose scale. Lime sulfur can be used on stone fruit to control diseases such as leaf curl, brown rot, rust and shot hole but only when the trees are dormant and leafless and just prior to bud swell. Lime Sulfur can be used on citrus, roses and vegetables to control specific pests and diseases during the spring/summer but you will notice that the concentration rate is at a much lower rate than what is used on deciduous plants. Copper sprays such as Yates Leaf Curl Copper Fungicide Spray and liquid copper can also be used to control and prevent fungal diseases at different times during the plant's growth. e.g. both of these products can be applied to the rose foliage when the disease is first noticed and then applied every 10 - 14 days to give ongoing control. These copper sprays can also be used on fruit trees to prevent against fungal infection at bud swell time to prevent problems such as leaf curl and shot hole. The Liquid copper and Yates Leaf Curl Copper Fungicide Spray can also be used during the spring/summer months to control other fungal diseases. Both of these products are registered for use on a broad range of fungal problems. With regard to your pruners, it always pays to keep them in good working order and serviced regularly. When pruning, to prevent the spread of disease, dip the pruners into a solution of bleach before moving onto the next bush or tree that you are pruning.
