Ended up going with this. I haven't put it out yet just checking here first before I screw something up. Prodiamine product.

Very good product, Prodiamine. I and numerous others that post on the H&G board use it. It doesn’t control everything, lawn burweed for example, no pre-emergents do, but you should be pleased with the results. Re-apply in late winter, usually before mid-Feb, for spring and early summer weeds.

While mowing the lawn Monday I came across the dreaded white moths fluttering in the lawn. This is a fairly new re-sodded lawn, centipede, at the end of June. I had some spectracide that I spread with the Speedy Green spreader I own. Am I following the correct protocol, or should I be approaching this differently? Also, lack of rain has stressed my lawn under a few trees, which is expected, and we are spot watering as needed.

Here is a fact sheet on tropical sod webworms and it lists recommended control insecticides - bifenthrin is not listed as a control measure but it should, I don’t know if it was an oversight but I’ve doubled checked with the AgCenter extension lawn specialists on this.
Tropical Sod Webworm LSU AgCenter Fact Sheet

I don’t know the active ingredient in the Spectracide insecticide you used - you can compare it against the list of recommended insecticides in the fact sheet + bifenthrin. You may need to re-apply whatever you use in a couple weeks if it has no residual life and b/c it’s granular you should water it in - follow the label directions on the insecticide you are using.

I haven’t had sod webworms in a couple years but when I do I typically use bifenthrin insecticide - in the past I’ve used granular Hi Yield Bug Blaster II (0.2% bifenthrin) and water it in - it has a residual life of 2 or 3 months.

used Triacizide(SP) by Spectracide. It includes treatment for sod worms and grubs, and other insects.

Just remember you are targeting the caterpillars that cause the damage not the adult moths, so the recommended insecticides in the article are most effective on the caterpillars.

Pre-emergent - I’d suggest either Prodiamine (product listed a few posts above) or Dimension applied in the next couple weeks. However, you are about 3 months since you’ve laid sod - you probably right on the edge, time wise, of being able able to use pre-emergent herbicide, which label states should only be applied to established lawns. If you believe your new lawn is well rooted in, then you can use it. Otherwise just wait until late winter (mid Feb) to target spring weeds.

None. You want annual ryegrass. 1 pound per thousand will usually do the trick.

You forgot to mention buttonweed, the Virginia variety.

That is now my lawn......

Drought stress

What are all these little dirt piles in my centipede?

Was a tad late putting down dimension this year. Put it down a week ago. Probably way to late but we shall see.

That was a bad video considering nothing is growing now. Use a thin layer peat moss in the spring.
