Prodiamine 65 WDG (Generic Barricade) is a pre-emergent that does not require a surfactant. Those would only be added with some post emergent products to treat actively growing weeds according to their product labels.
Prodiamine 65 WDG (Generic Barricade) should be applied during dry weather and then you water it in to get the barrier down. You can apply right before rain for watering in as long as not a downpour/heavy rain. It only needs to be watered in 1/2 inch. You would not want to apply during a rain storm as that can wet the granules in the hopper making them clump and not apply evenly.
Please refer to the product label for more information and application rates.
The Prodiamine 65 WDG (Generic Barricade) can treat between 2-10 acres depending on the usage rate required for your needs.

Prodiamine 65 WDG (Generic Barricade) can be mixed with Quinclorac 75 DF Herbicide or Tenacity Herbicide. However, make sure to do a jar test prior to doing a full tank to make sure it does not stress the lawn out & to see how they react.
Please refer to each individual product label for tank mixing instructions and follow the most restrictive label.
Aerating should be done prior to applying pre emergents such as Prodiamine 65 WDG (Generic Barricade) and can be done 2 times a year if needed (March-April and August-October). Do not aerate or detach lawns after pre emergent applications as this will disturb and break the barrier the herbicide is providing against weeds.
Effective pre emergent control of weeds is relies heavily on correct timing of the application. In spring, pre emergent applications need to be done when the soil temperature average is just under 55 degrees consecutlvely for 4-5 days. In the fall, pre emergents need to be applied when soil temps begin to drop to 70 degrees and continue to cool.
Pleae contact your County Extension Office for exact timing recommendations in your area or use Syngenta’s GreenCast Soil Temperature Website for soil temperature averages and current readings.
