What to do on St Aug in Feb

This is what I am/will be doing now - spraying weeds that already emerged with a winter weed cocktail (see image below), and the first week of Feb applying Prodiamine pre-emergent herbicide. Avoid spraying weeds during the St Augustine green up phase.

As you’ve learned some weeds “avoid” the fall pre-emergent but not many compared to no application.

Sod webworms have been such a problem for so many the past few years I think many will attempt to use preventive measures to mitigate the issue before they cause an problem. Insecticides containing bifenthrin are pretty effective, relatively inexpensive, and available everywhere. LINK (note: was bifenthrin is not listed in the article but Dr. Ring, the author recommends it as does Dr. Strahan the AgCenter turf grass extension specialist).

When would be a good time to do this?

Well the linked article on sod webworms might suggest mid to late summer, but honestly I’m no expert on this insect, and though I’ve had few infestations over the years they haven’t been severe.

I do treat my yard a couple times a year with granular bifenthrin primarily to mitigate flea issues (I’ have a dog as do surrounding neighbors, and I’ve never seen a flea on my dog) so that might be the reason I’ve not had significant sod webworm issues. I’ve used Ortho Bug-B-Gon LINK and it claims to have a 3 months of protection, whether that is true in our climate I don’t know, I usually apply the first application around May and the second application in August. Not advocating this particular product, but it’s readily available at the box stores and garden centers, not expensive, easy to apply - it’s a convenience product that seems to work for me.

Is it Okay to spread the weed cocktail and Prodiamine the same weekend

---

I would and actually will. One is is a pre-emergent and the other a post-emergent although the atrazine in the cocktail is both a pre-emergent and post-emergent. Just be sure to apply them at the recommended labeled rates and water in the pre-emergent after application unless you apply before a rain.

One more question, what is the mix on the Prodiamine per gallon/sq ft??

How many teaspoons of Prodiamine 65 WDG per gallon should I use to get a 12 month coverage?

Answer:
The first thing you need to know when using an herbicide such as Prodiamine 65 WDG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185-0.55 oz (1.1 tsp-3.3 tsp) per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.55 oz (1.1 tsp-3.3 tsp) of product with for each 1,000 sq ft area that needs to be treated.

Follow what WPBTiger said.

Can’t emphasize enough that the water is a carrier of the herbicide and not a dilutant per se. Use enough water in the sprayer to effectively spray 1000 sq ft, for some it might be gallon, 1.5 gal, 2 gal or more. For me , with the sprayer I use and the pace at which I walk while spraying, 2 gal of water is adequate to cover 1000 sq ft.

Just calibrate your sprayer by spraying water over 1000 sq ft in a concrete driveway. The amount of gallons of water it takes to spray that 1000 sq ft is the amount you should mix Prodiamine 65G into per 1000 sq ft of lawn.

I have some broadleaf weeds popping up, mainly in the vicinity of a 7 year old swamp chestnut oak in my front yard. Can I use the winter weed cocktail on them without worrying about negative effects on my tree? Or should I just use weed free zone and ditch the atrazine?

Same, have friggin dollar weed or something similar off and running right now

Thanks CrawDude. I’m gonna get this nonsense under control this year. I ordered the clegg’s winter mix ingredients and prodiamine. Lawn getting doused this weekend.

I have zero clover and very very few broad leaves, so perhaps my barricade worked this year, but I do have a few grassy weeds where A - I destroyed VBW, B - a hole dug by the city C - sodworms ate the grass.

I have weed free, MSM turf, 2-4d , and stuff for nutsedge, but no atrazine. what will work on the grassy weeds?

Can the prodiamine 65 WDG be included with the Winter Cocktail for 1 single application?
