Aphid Alert - 9 Aug 17

This is officially a high aphid year! PVY Vector Risk INdex values are much higher than last year's totals at almost all locations. With the increasing numbers of vectors, we strongly recommend scouting and the use of crop oils. Anti-feeding insecticides should be applied if required. We continue to see high aphid numbers as well as an increasing PVY risk index. High capture numbers are widespread across the region with 11 of 16 trap locations reporting close to or over 100 aphid vectors.
