In Cool-Season Lawns

General Treatment Info

Bindweed in cool season grass lawns should be treated with 2,4-D Amine in the spring when the bindweed has more than 10 inches of growth or when it is first starting to flower. Fall treatments are also very good when the bindweed is healthy and growing after the first fall frost. Bindweed will not go dormant in the winter until the temperature drops to around 22 degrees F.

Treatment Guidelines

  • Use 2,4-D Amine mixed with water at a rate of 1-2 ounces (1/8 to 1/4 cup) 2,4-D Amine in each gallon of water to treat 1,000 square feet of lawn
  • Use a pump-up type sprayer, do not use a hose-end type sprayer
  • Do not allow spray to drift to bushes and garden crops and do not spray when the temperature is over 80 degrees F
  • Do not allow persons or pets onto sprayed areas until the spray has dried completely
  • Do not use on creeping grasses such as bentgrass or St. Augustine grass except for spot treatments
  • Do not use on buffalo grass from the time it is newly emerged to the time the seedheads are in the softdough stage; You may use 2,4-D Amine on buffalo grass before it has started to grow in the spring and after it has made seed in the summer
  • Repeated spraying for years will be required to completely rid your lawn of bindweed
