Unfortunately we do not have the spreader settings for 0 - 0 - 7 Fertilizer with 0.42% Prodiamine and the manufacturer does not list that spreader on their bag. Due to the thousands of granules on the market and just as many different types of spreaders, you will want to calibrate your spreader to the product you are using and its application rates. You can see a short video on how to accomplish this below.
How to Calibrate your Spreader
0-0-7 with 0.42% Prodiamine is not labelled safe to be applied to carpetgrass.
