Downy mildew on roses treated with trichoderma

Our customer, Mark Neuhaus describes: “I have a beautiful 20 year old rambler rose, which has been regularly infected from downy mildew (botrytis cinerea). After spreading Avengelus F around the roots, I have been spraying the leaves every 2 months with a suspension, made out of water and 3 cups of Avengelus F and thus far the success ist evident.”
