Pro-Mate 20-0-10 Fertilizer with Barricade Pre-emergent needs to be watered in immediately after the application with 0.5 inch of rainfall or irrigation to activate the granules and best results. Application rates are based on the specific turfgrass you have therefore refer to the product label for your turfgrass and application rates.
For spreader settings, 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.
Please take a moment to watch our How to Calibrate your Spreader Video for instructions on how to do this.
