Fungicide was found Wednesday night on the side of a Coronado road, prompting a temporary street closure and hazardous materials probe.
The fungicide was located in "a container that fell off a truck," Sgt. Mark Porter of the Coronado Police Department said.
The container was spotted outside a home at about 8:20 p.m. and the probe was complete at about 10:25 p.m., according to a Heartland Fire and Rescue dispatcher.
The incident prompted the closure of Eighth Street between Alameda Boulevard and J Avenue, but all roads have been reopened since, the dispatcher said.
