Metairie area. Was thinking with the front it would be time. Should I wait another week?

I plan on waiting until next weekend. 10 year avg soil temps point to Oct 23rd for the Northshore.

Going to be doing Specticle. Just trying to figure out when we will be getting the necessary rain.

I put down Specticle last weekend and watered it with WeedFree Zone.

May take longer than that this year.... we're currently at a 5-day avg of 80 degrees. Though, next week with lows in the 40s and 50s will help us get closer to that 23rd target.

Put down Prodiamine WDG last weekend when it was supposed to rain on Northshore and soil temps neared 70. Never rained and fuggin got warmer. Sprinkler system watered in twice. Hoping for some rain next week to finish the job.

I also sprayed my whole yard this week with Weed Free Zone. Dang VBW started spreading again I have st Aug.

Need to pull the trigger on some Prodamine.

Any reason that I cannot spot sprayed Celsius WG, and full spray Prodiamine on the same day as spraying Iron?

St Aug in Lafayette

What do I need to do now to keep weeds out next spring?

I'd like to do weed control and maybe some sort of fertilizer to strengthen riits/grass before winter, if not too late

I'm in the same boat. Is there a cocktail I can put down to eliminate all the various weed types in my yard? Would generic Barricade and Weed Free Zone work? Or Celcius and WFZ or Prodiamine 65 WDG? My yard probably has every weed possible.

All? let’s say “Most”. Some weeds are perennial, e.g., Virginia Button Weed, can’t eliminate them but can can certainly suppress and keep them in check.

Pre-Emergent - Prodiamine apply ASAP to help control annual winter weeds whose seeds germinate at soil temperatures of 70 F which is occurring now, at least in Baton Rouge. Repeat application in early-mid-Feb, depending on your location, before soils temperatures increase above 55 F - temperature at which crabgrass seeds germinate.

Post-Emergent - Weed Free Zone is a good herbicide to kill numerous broadweed weeds, safe to use when temperature are less than 85 F. Combine with Atrazine for added affect if you don’t have a Bermudagrass lawn. 1 oz WFZ + 8.6 oz Atrazine + 2 tsp of surfactant applied in 1 or 2 gal of water sprayed over 1000 sq ft. Celsius is an excellent herbicide you should have and use without a high temperature restriction. Safe to use in the heat of summer when WFZ is not.

Post-Emergent weed control is a 12 month a year activity - spray them when you see them, the smaller/younger they are the easier they are to control. Not sure what to use - post on the board and ask - lots of knowledgeable posters here that can help.

Thanks CrawDude and Ronk. Soooo.......can I apply Prodiamine, Weed Free Zone and Atrazine (+ surfactant) mixed together or do they need to applied separately? I have St. Augustine and I'm in north Lafayette.

Forecast calls for mid to upper 80s through next Wednesday.

Honestly don’t know if you can mix Prodiamine with the WFZ+Atrazine mixture, hopefully ronk can answer that one for you, but you can mix Prodiamine with Celsius if you have it.

The Prodiamine does need to be watered in to be active and being that every day you delay applying it and watering it the more winter weed seeds are likely to germinate so I’d try to get down quickly - even if you have to do separate sprays with the pre-emergent and post- emergent. You are on the border line with temperature restriction on the WFZ - I’d personally wait until afternoon temps are mid-70s/low 80s to use it with the atrazine. But you can use Celsius now, or MSM Turf, with no temperature restrictions. MSM Turf is also a good post-emergent herbicide, $25 for a 2 oz bottle (can also be mixed with Prodiamine) - might be easier to find locally for you than Celsius - assuming you don’t currently have either in hand.

Is Celsius not better to use when its over 85*? Or is it just better because if its under that there are cheaper and maybe better options?

ETA: What I was trying to say is if you are in the high 70s to high 80s its kinda an in between zone right?

Well certainly Celsius doesn’t have the temperature restriction of 85 F that herbicides containing 2,4D have such as Trimec or Weed Free Zone, plus Celsius controls certain broadleaf weeds (Doveweed comes to mind) and grassy weeds that the Trimec type herbicides don’t control. The 2,4D in Trimecs can/will damage the lawn grass at 85 F +, the Celsius will not.

Basically Celsius can control about any weed that Trimec herbicides can plus a bunch more. Now I think Trimec types herbicides and Atrazine have higher efficacy at colder temperatures than Celsius so you can continue to use Trimec’s during the winter

Of course the upfront price of Celsius is much higher than Weed Free Zone, and I’ve not taken the time to calculate the cost per application per 1000 sq ft. But off the top of my head I don’t think there is much difference in over all cost per 1000 sq ft. I’m going on year 5 of my bottle of $100 Celsius and when I was using only Weed Free Zone I was buying 1 or 2 $25 bottles annually.
