Leaf rust is a fungal infection, and generally Trifecta Crop Control works well to treat fungal infections on plants. We have not specifically tested Crop Control on leaf rust but our customers have reported successful experiences treating rust, including one that left a 5 star review on Amazon of our RTU product. They reported that it took the rust away almost immediately, but they did not report what specific plants they were using it on.
Does this work on leaf rust on strawberries and blueberries?
