Stuck this in a different discussion on this, but a typical "clean" herbicide managed 40 acre field with minimal yield loss has about 2 million weeds. Take away the herbicide management and that goes to 6M-8M.
I think the real question here is what growth stages can you use this. I'm assuming the machine learning is good enough to use this during emergence and obviously pre-emergence. But I doubt you could use this VT or later. I suspect you can't even use it after V3.
Because if you can't use it after V3, then you still need a chemical or mechanical pre-emergent control or a way to continue to control after V3 (likely an over the top spray, which has its own issues).
