RoseClear Ultra provides the new industry standard and is a vast improvement on the original RoseClear, where re-application was needed every two weeks to give disease protection. Each treatment with new RoseClear Ultra now lasts twice as long.
Nothing could be better than the 3-in-1 action of RoseClear Ultra concentrate. A single spray as soon as you see the first few greenfly or blackfly will kill them within 24 hours so helping to prevent them multiplying into a huge population that could otherwise weaken your plants and disfigure the growth of stems, leaves and buds. The systemic spray will be absorbed through the leaves and move around the plant to give the treated plants, including any new growth, internal protection from both pests and diseases.
If rose blackspot was a problem last year you should collect up and dispose of any leaves that show the tell-tale signs of disease and start spraying your roses early in spring when the new leaves first start to unfurl. This will provide a clean start to the season that can be maintained with more regular treatments (do not compost infected leaves as the spores will survive and re-infect your prize plants).
Always read the label and product information before use.
