Background
Two acres of irrigated wheat showed curling flag leaves and honeydew coating last week.
Problem
Aphid colonies spread from field edge after a warm spell; neighbour plot already affected.
Method Used
Removed heavily infested tillers, sprayed neem oil 5% at evening, and released ladybird beetles on border rows.
Results
Spread slowed on 60% of plot; edge rows still need monitoring.
Challenges
Cannot decide whether to add a low-dose systemic or wait for natural predators.
Recommendations
Requesting guidance on economic threshold and safe intervals before harvest.
