Black Spot Disease On Roses – Rotating Chemicals
Q: I believe my unhappy roses have black spot disease. What should I do?
A: Black spot disease can rapidly make a rose raggedy. You can prevent the disease from affecting new leaves by spraying with a rose fungicide. The best practice is to rotate between at least two different fungicide chemicals. Propiconazol (Infuse), chlorothalonil (Daconil), and tebuconazole (Bioadvanced All-in-One) are commonly available. Follow label directions exactly. If you haven’t fertilized, you should do that now to encourage new growth.
