That's enough to cover 1,000 square feet. Spray enough to wet the leaves but not to run off. Seek a time allowing 8 to 12 hours free of rain. Be particularly careful not to get any of the herbicide on leaves of plants you don't want to kill. It can even cause havoc to young trees and shrubs if it gets on the tender bark. He advised garadeners and farmers to not expect 100 percent control of bindweek with one spraying.
