Cen Ks | For the last few years, I typically run flumio & glyph several weeks before planting. Then Zidua-Pro ahead of planter. Sometimes the the Z-Pro is substituted for Zidua. I understand some NAT folks have their reasons for not using Z-Pro, that's ok, In my cropping rotation, Z-Pro has been very good. My question is about the Sharpen. In my context, 1oz of Sharpen seems to be one reason the system works as good as it does. For 2026, a local agronomist suggested adding sulfentrazone to my program. He suggests doing the usual flumio early, then run Sharpen, Zidua,(rather than Z-Pro) & Sulfentrazone ahead of planter. The K-State weed book warns BIG time not to use Sharpen "as a tank mix or sequentially...with product containing sulfentrazone, flumioxazin or fomesafen within 14 days of planting".
First of all, what benefit will the sufentrazone bring to the program?
What is the K-State weed book referring to? It specifically warns against the Sharpen used in conjunction with ppo's
Give me your experience on this combination...
Or other chem options...
FYI: x. 100% no-till
x. heavy to moderate clay soil
x. avg planting depth:1.5+in
x, moderate to heavy residue
x, late May-early June planting = warm soil/good emergence
Thanks for your reply
