“The District Department of Transportation (DDOT) will begin the annual spraying of the female gingkgo tree (Ginkgo biloba) Sunday, May 8 from 9 pm through 6 am the next day until Thursday, May 12, weather and fruit development conditions permitting.
This annual spraying eliminates the formation of ginkgo fruit, which emits an offensive smell and falls on sidewalks and roadways. DDOT will use the same spray that it has used for the past 20 years, Shield-3EC 24(C).
Residents are advised that spraying will begin in Wards 1, 2 and 6, where female ginkgo trees are most prevalent, and continue through Wards 4, 3, 7, 8 and 5 in that order.
Spraying will occur during the evening for several nights. There is no need to move vehicles that are parked on affected streets. For questions, please contact DDOT at (202) 671-5133 or visit http://ddot.dc.gov/page/female-ginkgo-tree-removal-policy for a map of all the female ginkgo trees and more information.”
