24-D doesn't work very well on kochia here anymore. The only reason I used chem fallow this year was because of extreme wet for so long making it impossible to till earlier or in this case, plant. All I really intended to do with the spray was to set the weeds back until it was dry enough for the Flexi-Coil. Agronomist did recommend a splash of Dicamba to touch up on the kochia but I told him I'd use FE₂₆ for that and he figured that would work too. I'm actually well pleased with how well this tank mix worked on other fields. One of the last fields I sprayed had kochia nearing 4 feet high, along with a mix of other weeds. After 4 weeks, every one of the weeds on that patch looked like they were put in the oven and baked for a couple hours on 450. Very impressive. The main reason for the touch of E99 is that I'm starting to see a few Russian Thistle patches. Not much works on thistle anymore either, but E99 does.
