I have a question about Sethoxydim mixing. The Hi-Yield Grass Killer I’m getting is their 18% Sethoxydim solution. Instuctions say to combine with Hi-Yield Crop Oil concentrate, but the source I’m using doesn’t have that in stock. They do have the Hi-Yield Spreader Sticker Non-Ionic Surfactant concentrate, and they have Drexel Peptoil Crop Oil. Which of those two would be the better substitute?
I can’t specifically answer which of those is the better substitute, but I can say that I always use NIS in place of crop oil when I spray Clethodim.
