For example, Karl and Jagger both have good resistance to speckled leaf blotch. Shorter wheats seem to have more trouble with speckled leaf blotch because spores can splash to the flag leaf more easily. Resistance to the leaf spot phase and the glume blotch phase are probably regulated by different resistance genes. Therefore they are not well correlated. Usually, resistance to the foliar phase is sufficient.
Foliar fungicides are also an option for control of speckled leaf blotch.
Tilt is a systemic fungicide that works fairly well against this disease. Mancozeb is also effective, but is a nonsystemic type of fungicide that can be washed off by excessive rain. Quadris is partially systemic and has very good activity against speckled leaf blotch. Cultural controls are not very effective for this disease. Crop rotation or wheat crop residue destruction may have a small effect on the severity of speckled leaf blotch, but these practices usually don't give satisfactory control.
