Early infection, transmitted by autumn aphid feeding activity, is most damaging to crop yield, and can lead to further spread across the crop.
Following the restrictions on neonicotinoid seed treatment that came into force on 1 December 2013, growers now face a seriously increased challenge for aphid control to prevent infection. Furthermore, with more than 90% of the most virulent virus carrying aphids, Myzus persicae, identified as resistant to pyrethroid or other foliar insecticides, autumn Plenum WG (pymetrozine) application is key to providing protection. Treated at the first signs of aphid infestation, the novel action of Plenum WG quickly stops aphid feeding and protects against the spread of TuYV.
Plenum WG controls all aphids and provides the only opportunity to target resistant aphid populations in the crop, to break the TuYV transmission cycle.
