Q: What group fungicide is this?

The active ingredient is in 11. If you mix it with a fungicide from 3, like propiconizole, you have a decently resistant mixture that works well. Or rotate every 2-3 weeks.

Q: Do you neee to water the lawn after disease ex is applied?

Yes, you do need to water about 15 minutes after you apply the product for it to activate in your lawn. If you have rainfall do that will be sufficient. Apply to dry grass if you plan to wait to water in.

Q: Should this product be put down on dry or wet grass?

With most granular applications, it should be applied to dry grass. It will need to be watered in, but only a light watering is needed. It will not need the typical .5 inches to get it watered in. The reason for this is that wet grass is the last thing you need when dealing with a disease.
