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.

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.

You will need to use 0.185-0.55 oz (1.1 tsp-3.3 tsp) of Prodiamine 65 WDG per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area, note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.055 oz (1.1 tsp-3.3 tsp) of product with for each 1,000 sq ft area that needs to be treated.

Any difference in efficacy using Barricade granular versus spraying liquid?

If you are looking for something to kill existing crabgrass then you will need a post-emergent. Keep in mind that it may be too late to apply for a post due to the tiller stage of the crabgrass. The higher the tiller stage, the more difficult it is to control.

Prodiamine 65 WDG (Generic Barricade) should be applied at the rates specified on the table located on page 9 of the manufacturer's product label based on your grass type with sufficient water to obtain even coverage. You will likely need to calibrate your sprayer to determine how much area it covers before your application. As water is only the carrier of the product, the amount of water will vary depending on how much water it takes to cover your treatment area with your equipment. You can watch our video on How to Calibrate a Lawn Care Sprayer to learn how to determine the amount of water you will need for your specific type of sprayer.
