DDT is an insecticide.Well that makes us even. I don't believe a lot of things you say. I farmed for 27 years. 1 section is 640 acres. A quarter is 80 acres. The amount did vary if we rented land or not. The 1800 acres was just under 3 sections or 22 quarters. The reason they use roundup and DDT previous is that it kills weeds. It is poisonous. Even with using the roundup etc. we still cleaned our seed to clean out weeds. Both for us and our neighbours. If the amount of land is what you wonder. We were a very small farm. Our cousin crops 6000 acres and that barely keeps his family going.
It is too bad that Monsanto didn't stay with making football turf
A quarter is 160 acres
