Summary information as of 07-09-2017

  • Midlands - Low Risk

    • Aphid monitoring in seed potatoes has now ended for 2017 so this will be the final report.

    • Only one sample, from the Midlands, was received in the last week and this did not contain any aphids.
    • The total number of samples received for the year to date is 794.
    • Thank you all for participating in the aphid monitoring scheme this year. It wouldn't be possible without you all sending samples every week. I hope you have found it useful and that you will take part again next year. We'll be in touch in Spring.
    • I would very much appreciate any feedback you have about the scheme, both in it's usefulness and if there are any improvements you would like to see to any aspect of it.


      Along with the results from your aphid trap you need to take into account the following factors when considering the risk of virus spread.
