Early aphid alert issued
PEACH potato, grain and rose-grain aphids appeared much earlier than expected, according to the latest HGCA aphid news bulletin.
Forecasts predicted an average, or slightly early, first flight in late April/early May but peach potato and grain aphid have already been recorded at Writtle in Essex and rose-grain aphid at Wye in Kent.
The current spell of warm and dry conditions will lead to rapid aphid multiplication and the potential for early flight. Furthermore, drought-stressed crops tend to be susceptible to damage, warn Rothamsted Research aphid experts.
