Maybe Bridgey stands at the end of the row and blows hot air down the row twice a day. That would work.
Pesticides used at the end of the 2nd World War were used to maximise the amount of food that could be grown for a starving nation. The people took precedence over the wildlife. With hindsight DDT was wrong, and the current recommendation is to use as little pesticide as possible. No farmer spends money on unnecessary sprays.
The main pest I have on sweetcorn are squirrels, who stripped 60 cobs in an afternoon one year and carried them off through the woods. We found a trail of half eaten cobs.
