Applying propiconazole to severe fungus outbreak on lawn in Oregon's Willamette Valley. Is 40% better than 14%? Larger amount makes me nervous.

The key is rate and label. In general, one is just more concentrate than the other. When you apply it to the lawn you would use less of the more concentrate product. But in reality you would use the same overall amount on the lawn.

But lets get real, the turf labels are all 14% and that is what you should be using. There may be formulation differences that we do not know about that make it less of a problem on one crop or another.

Bottom line - use Banner MAXX or ProPensity and NOT Tilt, etc...... The label is the law.
