Narrative:The pilot was applying a fungicide spray to a field when the helicopter began to lose altitude. The pilot tried to arrest the helicopter's descent while turning by increasing collective pitch, which resulted in a low main rotor speed. The helicopter impacted trees and terrain. Examination of the helicopter revealed no preaccident mechanical anomalies that would have precluded normal operation.
Probable Cause: The pilot's failure to maintain main rotor speed while maneuvering at low altitude during an agricultural application flight, which resulted in an uncontrolled descent into terrain.
