Trap Catches Identified to Sept. 02
Only 4 traps reporting this week and all were very low. One green peach aphid was recovered in the Sabin trap. PVY Vector Risk Index numbers remain low.
We do need to report an error in our maps from last year - 2015 maps on the previous reported from this year actually shoeed trap capture and not PVY Risk Index values. This has been corrected. It is still interesting to compare the two years; averaged over all sites, the Cumulative PVY Risk Index values in 2016 are approximately only 1/10 what they were in 2015.
For those areas that have not yet vine killed, late season movement of inoculum in fields can still be an important source of PVY. So, if there's green material in the field, keep scouting....
