Susceptible cultivars are A203 and 849. Dr. Akinsanmi outlined the specific conditions/time when spores are abundant, as well as control measures.

When done correctly, mixing different chemicals in the same spray tank is a good way of reducing the number of spray operations needed and of saving costs. When done incorrectly, however, it can result in incompatibility issues leading to poor results or a big mess to clean out of your tank, filters, screens, nozzles and lines, or both.
