    How fast did that rain come down...there will be your answer. It's supposed to be watered in anyways, so a little rain is perfect, but long down pours might not be good.

    1" of rain was good. Crabgrass control should be good.

    it did come down fast like a down poor, for a little while, but then after words we got like 2 to 3 inches of snow which I am not worried about because snow melts slow not all at once, I just wish it would of done that first instead of the first one inch of rain, also what do you think about the 0.65 OZ of prodiamine per 1000K do you think I will get good control with that rate for crab grass control, also it was just one app not a split app.

    The mix rate on the product I use is in ounces (weight), so I use a digital kitchen scale for accuracy. I'm not sure how I could measure it differently. Some granular products, like Celsius do include a graduated cup for volume measurement, but I still use the weight measure for that. It's just more accurate that way.

    I use a digital food scale in ounces, or grams, it is granular, has to be by weight.

    The label gives you the equivalent in teaspoons...works well for me...

    I am not sure I understand, Cercopia.
    You put down.65 OZ per 1000 sqft. You used a 65 percent active ingredient product.
    Multiplying .65 times .65 equals .4225 OZ active ingredient per 1000 sqft.
    To find the pounds divide by 16. You applied .0264 pounds per 1000.
    To find the acres multiply by 43.560.
    You used about 1.15 pounds per acre as active ingredient prodiamine. Recommended rate is 1 pound per acre, and a bit less for fine fescue-- active ingredient.

    RigglePLC :

    I am just going by the label it lists :

    LBS. OF PRODUCT / 1.0 - 2.301
    ACRE

    OZ. OF PRODUCT / 0.36 - 0.83
    1,000 SQ. FT.

    you can use as much as 2.30 lbs per acre as long as you do not go over the 2.30 lbs per acre.
    here is the label I used it on tall fescue.
