| We seem to get them in mid august. We sprayed last year Aug 12th, year before that did not spray, year before that aug 15th.This was at 150 to 250 per plant. They seem to explode in a weeks time and seem to come from the east as spraying in jackson county is a week or 2 earlier than us.
I find very few of them now. If I sprayed now at 8th node and the plants put on 8 more nodes and tons more leaves, would not the systemic action be diluted by the first of aug??
Has anyone done this program??What were the results??Has there been any University data to back this up?? | |

Why are they promoting spraying aphids before thresholds??
