Officials said a Brooksville man got a surprise when a crop duster experienced a malfunction while flying over his house.

According to the Hernando County Sheriff's Office, deputies responded shortly before 7 p.m. Saturday to a home on Majestic Oak Lane to investigate a report of an unknown substance that was sprayed on the property by a low-flying plane.

The property owner, John Kyle, told deputies he was inside when he heard a plane overhead, and a short while later, when he walked outside, he found an unknown substance covering his yard and vehicle.

Deputies said they saw an odorless, light-blue substance covering about 1,000 square feet of the yard, including a vehicle that was parked in the front driveway.

Deputies said Kyle told them he had seen low-flying planes over his property due to his proximity to local blueberry farms, and also that ultralight aircraft regularly fly over the area.

An air traffic controller at the Tampa Bay-Brooksville Regional Airport  was unable to provide deputies with any details about the incident, deputies said.

A hazmat team was called to the scene to identify the substance, and they determined it was not poisonous. The team washed down the vehicle, driveway and yard. They also evacuated Kyle, who was not showing any signs of illness, officials said.

On Monday, Hector Blanco, the owner of Ag Aero Services, contacted deputies to give them more information about the incident. He told them that he had been hired to spray copper, an algaecide and fungicide, on blueberry crops in an area off Powell Road, near Kyle's property, deputies said.

Deputies said Blanco told them that he was flying to the blueberry field when a bird struck his plane's spraying mechanism, causing the chemical to be expelled from the plane and onto Kyle's property.

Blanco told deputies he had already contacted Kyle regarding the incident, and that he planned to go to the house to pressure-wash the driveway and clean up any remaining mess.

The substance caused no permanent damage to any property, deputies said.
