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. 

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.

She highlights that crops emerging after mid-April are at greatest risk, while noting that location can also play an important role. 

Aphicide resistance is an important consideration, but pyrethroid insecticides are still providing effective control.
