If the farmer is actually a subsistence farmer, they save their own seed, so they don’t care about the price of seed, nor would they buy single generation seed (say of a new crop or variety) knowingly. However, if someone nearby plants single generation seed, they can end up with genetic material in their variety of that crop, which cuts their germination (or seed baring) rates the following season.
