Google Siduron.

I have a feeling that is going to be hard to find. The only product I know I can get the has Siduron in it is Greenview seed starter+ crabgrass prevent and its only like 3% or 4% of the total product. I'm sure there are others, but is that low % ok. My garden center guy was saying to put down the Greenview step 1 feed and crabgrass prevent 24-0-6, it won't hurt the seed and will last longer.

I believe Scotts produces a starter fertilizer with siduron. I'm unfamiliar with the Greenview products. Whatever you use, make sure it is safe for the type of seed you are planting.
