Trimec Plus (be careful)

[Terraformer]

I used Trimec Plus (3 way w/post emergent crabgrass control) for the first time - on my own property. The warning about damage to KB and fescue is understated in my opinion. I mixed to the max and got significant yellowing of the turf - even with low temperatures (< 70 degrees). The good news is the crabgrass, clover and g-ivy are hurt real bad. We got rain the other day and the yellow spots are all but gone. Even though the product works, I don't believe the customer will be quite so understanding.

I haven't decided if I'm going to use as part of my general arsenal - maybe only limited use.

I burned a fine fescue lawn with MSMA. It did not kill the crabgrass, (July, years ago). Now I only use Drive for post emergent crabgrass control.

"Mixed to the max" sounds like your fault, not the Trimec's fault.

I think he's simply just passing along his honest experience to help those out who are considering using it. This isn't a post encouraging the blame game.

Thanks for the heads-up. As there are numerous zones and varities of grasses on this board, I will def. pay attention to my mixing ratio and test a lawn or two should I decide to use it. Take care.

You have crabgrass already?

"Mixed to the max" sounds like your fault, not the Trimec's fault.

When I stated "mixed to the max" I was referring to the max application rate as specified by the label. The label also specifically states "Injury may occur from this product to mixed stands of Kentucky blue-grass and red fescues (chewing fescue, creeping fescue and spreading fescues). If you are unwilling to accept some degree of turf injury, then do not use this product for mixed stands."

Believe it!

Not blaming Trimec... just passing on friendly information:dizzy:

Yup... primarily on south facing slopes that have thin stands of turf.

Sorry, but what happened to your turf is exactly what the label said. What was the surprise or the important information?

Thanks for your concern, but as I stated in my original post my turf is just fine. Since I always test products, prior to using commercially, there are never surprises - just observations. As to whether or not the information I posted is important... your words, not mine.

geeeeez!


someone passes along a personal experience and the lawn morality police come out in droves. the guy didn't come on saying "TRIMEC PLUS KILLDED MY LAWNZZZ!!!! I WANTS TO SUE!!!!" he just shared what happened and what he got for results. so many people here are so quick to jump all over others.

I'm not jumping on him so much as just saying he's stating the obvious.

how? i've never used trimec plus. before i make the investment in the product maybe i'd like to know others opinions, ones more educated in use of the product than i.

It did what the label said it would do. Big shocker.

[americanlawn]

Hats off dude --- You did what every label on the planet recommends........(try it first before you go wide-scale). It was also very smart to test it on your personal lawn. Again I say "hats off" to you cuz you did the right thing.:usflag:

I believe you are incorrect - the label states "Injury may occur". It only became "obvious" after I conducted a test in a controlled environment. No shock or surprises reported - again... you editorialize:confused:.

I did this on a KB lawn a long time ago....It grew out in about 4 weeks.

Great post. Thanks.
All info is good. Good things and bad things happened to the poster.
I hope you get control of your weeds.

Answers to this post prove the point: "The average guy is pretty stupid, and half of them are even stupider than that!" I have to remind myself of that sometimes.

Thanks for the report.

Trimec plus has been around for years, its a decent product but its a hot mix, no mater how careful you are. Im a big fan of pbi gordon products, i however prefer drive for crabgrass control.

Comparitively speaking, I would agree that it is a pretty hot mix. That said, it is doing a number on the crabgrass, thistle and BL weeds. Turf has recovered nicely, but discriminating customers may not be so understanding. Because of the results I'm getting I would use Trimec Plus for customers that have problem areas needing a drastic response. However, I would make sure the customer fully understands the short term effects.

[mikesturf]

I tried it once at "medium" rate and had yellow spots on my KBG. I'm staying with Speedzone. Still have 2 1/4 gallon jug of Trimec Plus left.

[mow2nd]

I've been using Trimex plus for a month now and haven't had a problem. I think the label says 3 to 5 ounces per gallon. I only mix at 3 ounces per. It doesnt take but a mist and those weeds are toast. I do agree you have to be careful.

Drive is great and is speed zone, Have you guys used "Surge?"

[greendoctor]

I use Trimec Plus on occasion. At 3-4 oz per 1000 sq ft NOT GALLON, it is relatively safe on zoysia and bermuda. I have even added the label rate of Image and simazine to this and it works even better on sedges and grassy weeds. Only reasons why I do not use more of this is I do not spot spray and many lawns are free of broadleaves long before I can erradicate the grassy weeds. I rather mix my own according to what is in the lawn.

[naughty62]

I have used it a few times on kbg/mixed lawns , usually new customer with crabgrass,large foxtail and others.I nail it full label when grass is not stressed and water good before.Apply it when there is no dew or rain is not expected for couple days.It does not stick the greatest .3gallon drench with a hose .Agitation helps mix it .Usually takes 10 days for good results and have to finish off the mature weeds with a second app at 3oz/ 1000/3 gallon .Do not apply to highly stressed grass, can be tricky during hot periods .The first time I used it I thought that the jug had been froze and seperated guey white gell .

[Shades of Green LService]

When i used it i never mixed more than 2 oz MAX and often mixed at 1-1.5 oz. p/ 1000.

Used it last late last summer and I absolutely love it.

[grassman177]

i have had great luck with it with little injury, just have to be real careful. it cant be hot or drought stressed thgouh, turf injury every time. i still have some for those(occasions) but have34 switched to Q4 for the future after a test run last year. good stuff maynard. i have straight msma on hand too, that will smoke nutsedge, but man is it hot!!!!

[cpa4t9r]

Appreciate the warning - was going to apply as a broadcast spray but will switch to spot-spray trouble areas with backpack to limit damage. Has some crab/goose in my ditch line that outlasted my Dimension pre-emergent app that I need to beat into submission.

What kind of grass has the crabgrass and goosegrass occupied. If it is bermuda or zoysia, there are ways to drop those weeds without causing much more injury than Trimec Plus alone. I actually cause less damage by broadcasting Trimec Plus at 3-4 oz per 1000. My issue with spot spraying is the overdosage applied in each spot.

Understand - I was definitely going to proceed with caution with the backpack. This is my 4th season in the house with original TTTF but I used TTTF/KBG last fall with really good results and plan to continue that regiment (I'm in Transition Zone 7).

The main areas where I need to control are as my yard slopes to my ditch in the front. The closer I get to the botton, the worse the weeds are. The face of the slope is much improved over last year so the Dimension performed better than the Scott's pre-M (likely Halts) plus better turf practices have increased competitiveness. The ditch is pretty shallow/gentle bend and the worst areas are right around the valley where the culvert is.

I've already applied Trimec granular twice (30-day intervals) so I don't have a lot of broadleaf pressure right now. May just pick up some MSMA w/out the 3-way. If that doesn't work, may have use glyphospate and paintbrush technique or dig them up.

I also have some sporadic orchardgrass that my landscaper probably gave me with the Rebel Elite seed he used :dizzy:. Its not excessive and my turf does a good job of crowding it out, but there doesn't seem to be a lot of options other than going nuclear in cool season grass.

[RigglePLC]

I used a gallon of Surge--I think it is similar to Speeedzone.

[alwaysgreenirrigation]

If you guys are as critical with your gf's and wifes as you are with many of these posters...you must never get any action....nuf said!!

[Weeds&Seeds]

What is a good replacement for trimec? I have used surge with great success, but is doesn't KILL nutsedge or crabgrass. Any suggestions?

[RigglePLC]

In my hands Surge with surfactant killed nutsedge--but I am not sure if it killed the roots. No effect on crabgrass--but I use Drive for crabgrass as a post emergent.
