Most of us have had some sort of weed problem in our lawns sometime or another. Others may have a weed lawn instead of a turf lawn because we’ve given up on having a healthy, vigorous, lawn full of turf instead of weeds. There is a way that you can control weeds from emerging and a way to control weeds that have emerged. All it takes is a little time, effort, patience and the correct, researched based information. There are two control methods against weeds that can help reduce the weeds that your lawn may have. These two types of herbicides are called a pre-emergent and post-emergent herbicides.
A pre-emergent herbicide is a herbicide that prevents the weed seeds from the previous year from germinating. The key to making this work is to apply the herbicide at the correct time. If you have trouble with crabgrass, the pre-emergent must be applied in Georgia by March 1 before the crabgrass seeds germinate. There are several products that can be used for various broadleaf weeds as well as crabgrass control such as:
1. Benefin
2. Bensulide
3. Oryzalin
4. Pendimethalin
5. Dithiopyr
6. Prodiamine
The second date to apply a pre-emergent in Georgia is by September, 15 which will help control the early spring weeds such as henbit, chickweed and annual bluegrass.
A post-emergent is a herbicide that’s applied to weeds that have already emerged. The type of herbicide to apply depends upon the weed variety that you may have in your lawn. Please contact our office for correct identification and weed control.
Remember: Read all herbicide labels thoroughly to be sure the product can be used on your particular turfgrass and that it controls the weed(s) you are trying to manage.
