How can I measure the Prime Source Chlorothalonil 82.5DF Select Fungicide by weight?

Do I need to buy a scale to get the correct weight needed to mix in a sprayer or is there a conversion chart to do this? For example 1/4 cup would equal 3.2 ounces if weighed on a scale?


The most accurate method to measure dry flowable powders would be to use a digital weight scale similar to what you would use to measure portions for food. Place a disposable plastic cup on the digital scale, zero the scale to 0.00 with the cup on the scale, slowly add the amount of Prime Source Chlorothalonil 82.5DF Select to the cup until you have the product label rates for your treatment in ounces measured.  Please view the full product label for more information.
