Black Streaks

Question

I wasn’t asking about streaks on leaves. I was talking about the beans themsleves. I can have 5 or 6 beans on one plant and 3 of them will have the streaks on them, and this is on different plants at different times. I can go for 2 or 3 days with no streaks then they will come back on plants on the other side of the yard.

Answer 1

Sometimes this happens as a result of adverse weather conditions, or it could be the particular variety as well.
