Should I have put down more pre emergent last month?

Feeling like I missed an application somewhere…
Located in New Orleans area, roughly 2000 sqft yard. I put down 7.2lbs of Barricade on 10/16 and 1.5 oz of Simazine on 11/18. Barricade max annual rate is 14.4 lbs/2000 sqft, Simazine max annual rate is 3 oz/2000 sqft.
Grass is totally dormant now and I haven’t put anything else down since. Should I throw down some Atrazine or Winter weed cocktail soon?

Do you have any winter weeds showing up?? What's the recommended application rate per 1000 sq/ft for those??

Nothing but some clover here and there.
For app rates, the labels state:
Simazine: 0.75 oz per 1000 sqft
Barricade: range from 3.1 to 7.2 lbs per 1000 sqft

Finally I can enter back into the chat. No, you didn't miss anything. That would be three pre ems in a row. You are going to cause root clubbing if you continue. Pre em doesn't work on perennials so if you see those popping up no big deal.
I play around with my yard and this year I only did a half rate of simazine one time. I did this because I had no winter weeds last year and therefore no seeds. I currently have no weeds. The least amount of pre and post you can use the better for your overall lawn health.

Is it time to treat the lawn with a winter weed cocktail? Or are the temps coming up in south LA too cold?
Atrazine plus weed free zone is the cocktail I am going to use. I put down simazine in the fall and the yard has only a few green weeds now - kyllinga.

I applied based on the max annual rate - thinking was I’d do a spring and fall application of Simazine. Same for Barricade. I didn’t consider how long either would actually be effective in the soil when I made that plan though. That’s my main concern, don’t want my pre-ems to not do their job because I wait too long between apps.
