Prodiamine 65 WDG - Pre-Emergent Herbicide (generic Barricade) is a pre-emergent weed control designed to stop weeds in the lawn such as crabgrass, annual bluegrass (poa annua), bittercress, chickweed, and henbit. This is a dry product you mix in water to make a liquid to apply via backpack/battery sprayer.
Prodiamine 65 WDG is a professionally formulated pre-emergent to be mixed in water and sprayed out as a liquid. Yard Mastery is proud to bring this to market specifically in a smaller bottle for DIYers.
Most DIYers use this product in spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, then towards the later fall drops seeds. The following spring the process starts all over again. This is why crabgrass is called an “annual” grassy weed. The good news is that it can be stopped very effectively using this product.
The best time to apply Prodiamine is in the spring or fall as soil temperatures are between 55F to 70F. This will give you approximately 3 months of pre-emergence protection.
For more details, you can check out the FREE Pre-Emergent Guide. If you download our FREE app it will tell you exactly when your soil temps cross these milestones.
For cool and warm-season lawns, our recommendation is 2 applications in spring if the target is crabgrass.
FOR LARGER LAWNS, you can purchase a five-pound bottle here.
DO NOT use Prodiamine if you are seeding or reseeding as it will keep your seed from germinating.
