well i bought some Schultz "Garden Safe Fungicide 3". It's 3 garden products in 1 and organic. Fungicide( Controls black spot, rust, powdery mildew), Insecticide( Controls whiteflies, aohids & itger pests), and Miticide( Controls spider mites & other mite pests). Look's good, i'll be applying it for 7 days straight, and maybe 7 more so it doesn't get infested again. I'll let you know how it works.
