Breeding of resistant lines has seen minimal acceptance in the Americas but more widespread success in Europe, though the durability of this resistance is always a concern. More recently, biofungicidal methods of control have emerged in studies with some promise being shown by the organism Microsphaeropsis ochracea in reduction of initial ascospore inoculum of up to 70-80 percent. While still requiring a fungicide application, the use of the proposed mycoparasite allows for a delayed and lower volume use of chemicals.
