Product Description:
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 cool and warm-season lawns, our recommendation is 2 applications in spring if the target is crabgrass.

Application Information:

  • DO NOT use Prodiamine if you are seeding or reseeding as it will keep your seed from germinating.
  • This product should be applied via a pump sprayer or battery-powered hand can. NOT recommended to be applied via a hose-end sprayer. Always read the label and follow safety equipment recommendations.
  • We recommend weighing this product on a scale to be accurate and grams will be the easiest. See the following table for the application rates we recommend. The product must be watered in within 48 hours, sooner the better. ½” of water from irrigation or rainfall.
