NATRIA Rose and Flower Insect, Disease and Mite Control, Ready-to-Use, 24 oz

My roses consistently get black spot and other problems due to the high humidity and extra hot sun. I've tried several products but this one seems to work best, especially if mites get onto the new flower buds. Try it before the sun gets too warm or late evenings, as roses don't like wet leaves.

I have used every products on the market including this products but nothing worked except one crazy item that may shock you as following... before I mention it I would like to say that there is no single products or artical explains the cause of plant disease like finagle however, they just sell you a product to treat it well, the only item I used to kill every single disease and underground hateful insect is by mixing 1/2 a cup of bleach to 5 gallons of water then feed each plant 5 cups of the mixture. I swear it cured my Rose bushes from all diseases and they grew faster than ever also they started to produce a huge flowers and they produced dark-shiny leaves. Spraying the leaf because it's infected with diseases such as fungle and others will not solve the problem because the problem is under ground not above it. I respect this product and the other products in the market so that's why I gave it 5 stars but trust me bleach is sounds crazy but it did work as if a miracle happend.
