Bonide DuraTurf Weed and Feed 16 - 0 - 8 is a granule so would not volatize.
We carry Bonide DuraTurf Weed and Feed 16 - 0 - 8 that is labeled as phase 2 & we have also have Bonide DuraTurf Crabgrass and Weed Preventer for Lawns and Ornamental Beds which is phase 1. No other phases at this time but are working on it!
