Q: Why choose 0.38% Prodiamine over 0.28%?

A: The 0.38% rate delivers a stronger, longer-lasting pre-emergent barrier — ideal for properties with repeat crabgrass problems or high-pressure weed situations where standard rates haven't been sufficient.

Q: What does 100% SurfCote mean for nitrogen delivery?

A: All of the nitrogen is encapsulated in Knox's SurfCote polymer coating, releasing slowly and evenly for up to 4 months. This eliminates the quick-release nitrogen fraction entirely — providing maximum control over feeding.

Q: Is the lower nitrogen (10%) a disadvantage?

A: Not at all — a 10% nitrogen analysis is strategic for maintenance-stage lawns or mid-season applications where you want pre-emergent coverage without pushing excessive top growth. Pair with a higher-nitrogen fertilizer in fall if needed.

Q: Can I use this product with an overseed program?

A: No — Prodiamine will prevent seed germination. Do not overseed for at least 3–4 months after application. If seeding is in your plan, apply after establishment is complete.

Q: Where do I find application rates and timing?

A: On the manufacturer's product label. Current label links are being added to this page. Until then, stop by any Champion location or contact us and our team will get you the label information you need.

Q: Is a Safety Data Sheet (SDS) available?

A: Yes. The SDS for this product is on file and available on this page and at the counter, including for contractor accounts.

Q: What does 100% SurfCote mean?

A: SurfCote is Knox's polymer-coated, controlled-release nitrogen. The percentage tells you how much of the bag's nitrogen is coated for gradual release.

Q: Can homeowners buy this product?

A: Yes. Shaw's products are sold to both homeowners and professionals at all four Champion locations. Always read and follow label directions.
