It’s the same active ingredient the pros use, formulated for easy DIY application. Product Label & Specs (PDF): Key Benefits Prevents crabgrass, poa annua, and other common lawn weeds before they emerge Safe for all established cool- and warm-season grass types Provides up to 3 months of pre-emergence protection per application Same active ingredient the pros use (.37% Prodiamine) Easy DIY application with clear instructions Most DIYers use this Prodiamine in the spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, and then, towards late fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grass weed. The good news is that crabgrass can be stopped effectively using this product. The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55°F and 70°F. This will give you approximately 3 months of pre-emergence protection.
