Dr. Louise McNamara, a researcher with Teagasc, is on this week’s Tillage Edge to talk about the threat posed by aphids and, consequently, BYDV this season.Â
Â
Louise explains that the thresholds, or triggers for action, are similar to previous years, although ongoing research is expected to refine these in the future.
Â
She highlights that crops emerging after mid-April are at greatest risk, while noting that location can also play an important role.Â
Â
Aphicide resistance is an important consideration, but pyrethroid insecticides are still providing effective control.
