Doveweed – Identification and Control
Q: What is this weed and how do I kill it without killing the grass. I have sprayed it with Weed-B-Gone and I can not kill the weed that has made its way into my new sod.
A: This looks like doveweed to me. If so, it is VERY difficult to control! It looks like a grass but it is a broadleafed plant instead.
You will have to be persistent…and it may take two years to get it under control.
If it is in a small area, the best course is to dig it out as soon as it’s seen.
If you choose to control with chemicals, you must pursue two avenues: applying a pre-emergent at the right time in spring and applying a post-emergent on the leaves that escape the pre-emergent.
It may take experimenting to see what works best.
I recommend you apply dithiopyr (click for sources) in mid-February and again 4 – 6 weeks later. This will prevent some of the doveweed seeds from germinating.
When you see leaves emerging in May, it’s time to apply a post-emergent. Apply Bayer Season Long Weed Control (click for sources) according to label directions. If you don’t observe adequate control, apply Ortho Weed B Gon Max (click for sources) in August.
Repeat these steps in the second year.
BE SURE TO READ AND FOLLOW LABEL DIRECTIONS EXACTLY OR YOUR LAWN GRASS MAY BE DAMAGED.
