I'm wondering how much yellowing is now showing in others' beet fields, and if there is any correlation to the insecticide spray programme. Here all fields are showing patches of yellowing. A month ago just isolated plants, or small groups of plants. Seems to have progressed over past month, so now looking worse. Complete lack of any yellowing in areas that emerged late - some as late as 2 months after first emerged areas! We monitored frequently and carefully between emergence and 10-12 leaves, and only sprayed if threshold numbers of wingless green aphids found. 2 sprays mostly, 3 on one field. Is beet becoming yet another break crop losing its appeal?
