Sugar beet focus Emergency authorisation granted
for sugar beet aphicide • Monitor crops closely for virus yellows • Treat in accordance with IPM guidelines • Move quickly when threshold reached

Biscaya (thiacloprid) to prevent virus yellows infection by con- trolling peach–potato aphids in sugar beet.
The emergency authorisation
was applied for by British Sugar and the NFU. It permits up to two treatments of Biscaya per crop at a maximum individual dose of 0.4 litres/ha until 15 August.

monitor aphid numbers – has been doubled this year to provide growers with advance warning of any potential problem in sug- ar beet crops, says BBRO head of science Mark Stevens. “There are 60 evenly distrib- uted throughout the four factory areas and catches will feed into an interactive map where sugar beet growers can view their three closest water pans simply by en- tering the farm post code.” Crops should be monitored as soon as the network shows that winged aphids are being caught in the locality, says Dr Stevens.

Swift action
Assessments should be record- ed in accordance with integrated pest management (IPM) guide- lines.
Growers should act promptly when thresholds are reached, says Mark Stevens

Previously seed treatments were at work when winged aphids entered crops. But foliar spray- ing means there is often a time lag between threshold identifi- cation and product application. Growers should move quickly to control aphids when the thresh- old is reached.
