Aphid Survey 2019

Maps showing aphid flight pressure by site, week and cumulatively from mid April - July 2019.

The aphid survey for 2019 is closed.  A full report will be released once the extent of infection across the beet area has been determined.  As expected the aphids first appeared in the south of the growing area and migrated north.

As part of endeavours to find solutions for growers against these viruses, the BBRO have conducted a Variety Virus Trial.  No conclusion can be made until harvest has been completed but differences can be seen between varieties in the amount of yellowing  in the canopy.
