Formerly NE North Dakota, now NW MN | Are you finding aphids already?
I guess I would hold off until 250 if you have a seed treat on. The forecast is cold-ish and dampish and I think whatever fungus attacks them will probably go hog wild, so if you have cruiser or gaucho on I doubt we'll see populations explode this early.
Still that hope might be colored by the hope that we don't have to start spraying aphids before july 15th. |
threshold for aphids on beans still 100
