Another week with high aphid pressure. We are seeing more green peach aphid across many sites including a whopping 18 from the Sabin trap! Soybean aphid numbers are still high. Several locations have risk indices in the double digits: Ada, Perham, Sabin, and Tappen.
As always, keep scouting!
The PVY Vector Risk Index numbers on the table represent the amount of pressure in comparison to green peach aphids that is occurring at any given site. The cumulative seasonal PVY-VRI up until Aug 17 for all sites is presented on the first map, the second is the total regional PVY-VRI from 2014.
