Thanks for doing this!

 

I had good results killing oxalis with T-Zone in tests I did about June 9, 2011. Worked better with surfactant. Not much effect on violets, although adding surfactant helped.

Check the label--Drive is very effective for violets. (And crabgrass). Only problem is that Drive sometimes settled out in the tank when I used it.

Let us know what happens under your conditions. Your oxalis will be a little more mature in Ohio, rightDGW ?

Under my conditions, my hand sprayers cover about 2000 sqft per gallon--so naturally I mix it stronger. Spray some water on cement to find what square feet your backpack covers.

you are correct some are more mature, but the trimec did knock back a bit of them

i dont blanket spray with my BPs(unless something breaks ) , so i havent calibrated , i just spot spray

i used the low rate , because tomorrow i plan on mixing with the high rate and a sticker to spray some other sites to compare results

 

Yes, Please let us know how you make out.

 

day one-oxalis is crispy brown and stems are twisted, violet has slight browning , and nutsedge is wilted

no damage to surrounding grass

 

I found Surge to be very effective and less expensive. How is T-Zone with 90 degree temps?

on oxalis?

havent tried in hot temps yet

 

Yes, decent results with them. Heavy areas I go over twice (Permagreen). In any event, way better results then say 3way.

This was in close to 90 degree temps.

I got mixed results with T-Zone, but the cost was the turnoff for me.

thanks for the info , i will check it out

Spreader sticker is your friend with these tougher weeds.

I found that spreader sticker was costly in the skid sprayer. But cheap in hand sprayers and back packs, as a spot spray. Labor and time consumed is the main cost in spot spraying.
Only problem is: the silicone surfactants are difficult to measure in spot sprayers because you don't need much. For the silicone surfactants you use about one-tenth of one percent. Say around a tenth of an ounce per gallon in a hand sprayer. Ten cents.
Which is good because silicone surfactants cost about a dollar an ounce.

How do you measure small quantities?

 

I used T-Zone on a dandelion and it worked very well at about 7 days later. I also used T-Zone on new grass seed planted in pots when the new grass was about an inch high. So far only slight injury to new grass. Stay tuned.

 

i do have a couple gallons of lesco spreader/ sticker


i wanted to try it out without it first

i still havent tried it with the sticker, im hoping i get a chance tommorrow

 

today i mixed 1.5 ounces per gallon with lesco sticker

it is about 90 degrees

i sprayed some oxalis in an irrelevant part of my yard

i want to take pics but my phone screen is broken, and when i try to load regular camera pics on this site it always says they are to big

i have no clue how to get them on here

All you have to do is get the photo on your computer

right click on it and click go to edit

than go up to the top and go to image and than to resize make it small enough so you can see the hole photo on your computer screen

some times you have to resize it 2 times

I read on the label only apply TZone up to eighty five degrees F. Hotter than that, the ester Triclopyr will volatize.

 

i have had issues despite spreader/.sticker with surge killing oxalis for the most part. kinda pisses me off, but it is only when dry, after a rain the kill is great, but in a slight drought or more forget it, it burns the top and then regrows. i have not found a weed control that works super in slight drought conditions yet.

any thoughts?>

with the t-zone the tops are brown and the stems are curled and turning dark red

On what kind of grass? Cool season or bermuda? On bermuda, metsulfuron is a very good control for oxalis. It seems as though the product hangs around until there is water. Based on the AIs in Surge, I would expect mostly a top kill of oxalis. If I want a root kill of oxalis, that usually is provided by high rate dicamba, triclopyr or metsulfuron. If the turf is tolerant, T Zone would be another option because it has a high rate of triclopyr ester.

 

greendoctor,

I think by looking at location:__________,___ that for the most part, we are all talking about cool season grass. But your info is good to know!

The drought issue is very important. Most plants slow down their metabolism in stressful conditions. To a point, even crabgrass!

Great info guys!

yea , even the label recommends a good watering 24 hours before and after app

but we all know what the chances of that are in most cases

 

Don't forget no mowing 3 days prior, and 3 days after!!! lol
