I am going to distribute ferterlizer through the hose system several times a year and would like to add Oryzalin in the tank as a pre emergent I am concerned the colorant might clog the soaker hose is it available without the colorant.
The orange color of Surflan Pro Herbicide (Oryzalin 40.4%) is a trademark and cannot be taken out. We apologize we do not have a liquid Oryzalin 40.4% product without the colorant.
