Ronk, is this the stuff you’re talking about for perennial rye?

Trimec

No - I take care when spot spraying to keep the herbicide from contacting shrubs; ditto with glyphosate (“Roundup”). Atrazine you want keep out of landscape beds.

That is it. the 2-4D may cause some yellowing. If you can find it a reasonable price Trimec Encore is better. They both have MCPP and Dicamba. Encore replaces the 2-4d with MCPA. Less yellowing and still great knockdown.

I used specticle flo in September and have a little burweed and some dollar weed. Will spot treating with celcius work this time of year?

Yes, but make sure you read the label and use it at the correct rate.

Celsius works better in the hot months. Louisiana may be getting hot enough during the day but I'd use something else. MSM or the winter weed mix.

Do you need to treat lespedeza now?

I’ve had good success with MSM Turf (metsulfuron methyl) which you could spray now. During summer/warmer temperatures I usually use Celsius. Actually had pretty good control of lespedeza with Fertilome Weed Free Zone before I started using MSM Turf and Celsius in the lawn, which you could also spray now. .

I had the best luck in summer treating lespedeza with MSM over Celsius. It could have been I didn’t use the max rate or Celsius but MSM did a good job. I also tried a product called Changeup and it did the best.

A herbicide I’m not familiar with but I see it’s another Trimec type herbicide that has fluoxypyr substituted for the 2,4 D.

Yeah I got the idea from Lawncare life and Pauls Prime Cuts on Youtube. Both have weed control and fertilization businesses in the south and seem to favor it for lespedeza.

I don’t have to do it now necessarily, but will do whichever you think is the best time to get results.

You shouldn’t have to treat it now. If you have some still living then it’s been a very warm winter. It is best to treat it when it’s young.
