Here fava beans are known for often getting lots of black aphids at the top of each plant, and then when they’re bad they can spread downwards. The usual advice is to pinch off the top few inches to discourage them. It doesn’t affect the developing bean pods and the tops are also good to eat!
So all round, it’s worth a try.
