“The District Department of Transportation (DDOT) will begin the annual spraying of the female ginkgo tree Monday, May 1. The spraying will occur from 9 pm through 6 am, weather permitting.
The 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 Ward 5 and proceed to Wards 4, 3, 2, 1 and 6. There are no female ginkgo trees in Wards 7 and 8.
Spraying will occur during the evening for several nights. There is no need to move vehicles. For questions, please contact DDOT at (202) 671-5133 or visit here for a map of all the female ginkgo trees and more information.”
