DLM Farms Inc., a Sanger, Calif.-area citrus grower-shipper, has been ordered to pay a $2,500 fine for allowing a fungicide spray to drift into a road adjacent to a tangerine grove, a violation of federal pesticide regulations.

The company pled guilty Dec. 2 to the misdemeanor in Federal District Court in Fresno.

According to local news reports at the time of the 2008 incident, an employee responsible for alerting the spray rig operator to vehicles entering the roadway left his post. The spray drifted into a school bus occupied by eight students and the driver.

DLM Farms earlier paid a $3,700 fine to the Fresno County Department of Agriculture, according to the county staff, and paid more than $7,500 restitution to the students and driver.

Attempts to reach DLM Farms were unsuccessful.
