In non-Cruiser SB treated fields, aphids were beginning to be found from the end of April onwards and peaked towards the end of May. In Cruiser SB treated fields, green wingless aphid numbers were largely suppressed during April and May and, in most cases remained below the threshold for additional aphicide spray treatment. In early June, there was an increase in green wingless aphids but to a much lower level than fields that did not use seed treatment.

End of season virus scores were hampered by the effects of drought and beet moth. However, samples of symptomatic leaves were tested for virus. This showed a higher prevalence of Beet Yellows Virus than Beet Mild Yellowing Virus/Beet Chlorosis Virus.

The presence of green wingless aphids found on the crop will trigger a change on the map as follows:

• Grey map point =  no data received
• Green map point = data received, no aphids found
• Amber map point = data received with aphids found but below spray threshold
• Red map point = data received with green wingless aphids found and spray threshold reached.
