Trap Catches Identified to September 08
Greetings!
Welcome to the Aphid Alert update for the week ending September 08. The colder weather has brought along at least one good thing, the aphid vector numbers took a real tumble this week.
With only 6 sites reporting this week, only 34 vector aphids were recovered from across the area (that number was 244 last week!) Only one site had vector numbers in the double digits; Humboldt reported 12 vector species (compared to 93 last week). No Green Peach Aphids were recovered in the past week and Soybean Aphid numbers likewise were much lower.
Many locations have already vine killed. This would be a good year for early vine kill; if fields haven't yet been killed, this would be a good time to think about it
Remember, keep scouting!
