I can't figure out what ratio to use for this...mainly the water.

Check out this tread posted by G-man and scroll down to the section on spring. There are a lot of great references created by him and other members listed there to show you how to apply and at what rates.

G-man has created a excel spread sheet that you can download and adjust the values of the square footage to meet your lawns dimensions as well as GrassDaddy has a YouTube link there of how to apply and he has a link on his video to a calculator you can use based off your square footage to calculate how much Prodiamine to use for you size, grass type, and desired coverage period.

As for the water requirement I believe it states no less than .5 gals/M but I believe most use about 1 gal/M. Some may correct me on that...

It states to use a minimum of 20 gallons per acre. So, depending on your area you need to use a minimum of 1 gallon of water per 2200 sq ft (technically 2178 sq ft). As long as you're mixing the right amount of product for the given area of land, you should be good to go.

The amount of water doesn't matter.

I like to use lots of water and do multiple passes, I feel more confident in getting a uniform application that way.

Get a sensitive kitchen scale to weigh out the product. You don't need much.

I'm still unsure of myself so I'm going to see if I get a response before I try tonight.

Prodiamine states .55 oz per 1,000 sq ft. With 2 acres than I am .55x 86= 47.3

I have a 5 lb container- 47.3 oz = 2.95 lbs.

Sound right?

Your profile says you have Fescue.



So you can apply a rate of 1 lb per acre all the way up to 2.30 lbs (max dosage).

If you have other grasses mixed in like KBG or PRG then your rates would change to .5lbs to 1.5lbs per acre.

Keep in mind that's the max dosage for the year, not max dosage per application. So if you want to do another application Later in the year for fall weeds then you have to account for that now.

2 acres at 0.65lb of ai/acre = 1.3lb of prodiamine.

Prodiamine is measured by weight and not volume.

 

[mpoland33]

darn...ended up doing about 2 lbs of it.

I dont know why I have such a hard time figuring it out. I went to g-mans excel sheet but its view only so I can't change anything.

Thanks for the tip on the yearly max...I didnt realize that.

Go open it again. Go to file and select Make a copy

This way you have your own version to add your numbers.
