How much water to mix with Propiconazole?

1G/M. If foliar disease, let it dry before rain or irrigation. If soil borne, water it in after application.

If you need 3 fl oz/ M, then use 3 gallons of water. Why use more water?

Because the label probably says to use at least 2 gallons of carrier / 1000 sq ft. I think all or most of the fungicides that I use have a recommended 2 gallon minimum. But I always use just 1 gallon with no problems noted.

Label has no recommendation as far as carrier water requirements. Most do recommend 2G/M. However it is a major effort for people doing it with their backs. I have a 20G rig I built for my zero turn so only effort is filling the tank multiple times. Hauling a 4G backpack around the yard will putting a hurt on a Marine.

I would want to use more than 3 gallons of water because if I want to treat my entire lawn, and I am more familiar with applying 4 gallons using my backpacker for 6000 sq ft in my yard. Since the Propiconazole label calls for 1/2 oz. per 1k sq feet, that would be 3 oz. If I were to use only 3 gallons, I would need to heavily adjust my walking speed.

Unless I am misunderstanding something, that is...

What are you treating/preventing?

If it is soil based go ahead and put 4G and immediately water in.

If it is foliar, then use 3G with 1.5 oz of PPZ and slow your walk so you cover 1/2 the lawn. Repeat for the other 1/2. You need enough carrier to throughly wet the blades and go into the thatch..

If you are only preventing, you might get by with 4G/6M, but you wont know until a problem develops.

I'm treating dollar spot on part of my lawn, and preventing it in another. It has already hit part of my lawn which is located at the bottom of a berm. It's a section of my lawn that I don't care much about since it's not really usable, but I'd still like to treat it because it looks ugly. However, I figure it also might be a "canary in the coalmine" situation and that dollar spot could threaten the upper section of my yard near my house, so I'd like to do a preventative treatment for that.

If you are using 0.50 oz/M that is a preventative rate, so for curative rate you need a kicker like Daconil every 2 weeks and up your rate to 1.0 oz. You can go with 1.5 to 2.0 oz every 2 to 3 weeks, but no more than 3 apps, then switch fungicide.
