Castings tea is great for introducing more beneficial organisms to our soil and as a foliar spray. But here's some info on using tea sprays to prevent powdery mildew on roses and ostensibly any other leaf that is prone to the disease. A c+p and the link to the whole article. Also a youtube vid if you want to make it yourself.
Castings Teas suppress disease and pests on vegetation and will boost the crucial microbial activity known as the Soil Food Web (SFW) which is so crucial to organic soils. Perhaps the most widely used and known use of teas is to suppress/eliminate black spot and powdery mildew on roses. By spraying Castings Tea on the surface of leaves, you are doing two things. First, you coat the leaf with millions if not billions of microbes all competing for a food source. Some, for instance protozoa, eat bacteria which may be eating decaying plant material. Others eat other microbes and their wastes. In the end, there are not enough resources for the harmful molds and fungi to flourish. In addition, you are also coating the leaf with a protective surface that protects the leaf cells from attack by foreign spores or airborne microbes. Finally, by inoculating the soil with Castings Tea, microbes break down nutrients for uptake into plants thereby increasing plant health and the plants own disease resistance/suppression.
