I have been working on moving the lawn where I have moved to, towards Tier one standards. I have sprayed twice with Broadleaf control . The first time was with Q4+ in which the broadleaf control is one half or one third rate. (Thank you Matt Martin , the Grass Factor!) After realizing it was a low rate , I bought a jug of Gordons Trimec at Rural King and went out with a full rate of that.

Anything Broadleaf is certainly reduced but I had a ton of African Violet it seems to be begging for another application. Does anybody have experience or opinion to share regarding the spacing timing and strength of repeat apps of broadleaf control.
You certainly can tell stuff has been sprayed but there are also just yellowed and stunted weeds that don't look like they are dying yet. (week to ten days post).

Personal experience. The longer it takes to kill the better the kill. Sometimes I will spot spray back to back days. I like doing east - west, then next day north - south. Helps me get a better picture of anything I missed the day before! I spot spray at least 3-4 times per month. I am a huge believer of doing a half rate application twice to get a more even spread. Hope this gave you something to think about!

Have a great weekend!!!!!!!!!!!!

For violet you should use triclopyr. At rural king it is called "brush killer". Get some non-ionic surfactant too.

I have a variety of surfactants available.
The reason I didn't buy some triclopyr is that the jugs are already multiplying beyond all reason. :roll:
I got Gordon's Trimec because I have used it before but have never used triclopyr and I guess when I was standing in the aisle confronted by a truly HUGE assortment of products I went with what I knew.
I guess there is another jug in my future.

For wild violet, the Ortho CCO is triclopyr & if you only need a bit, a small bottle of somewhat diluted concentrate is only 10 or 20 bucks at the big box stores. Mix per label. You can reapply in four weeks for anything that needs another shot.

Also, Hi-Yield packages relatively snall bottles of real deal triclopyr (Turflon ester) for about 30 bucks.

You have a big lawn so likely even a large jug of Turflon won't go to waste. If you just want to try it out, the smaller bottles won't break the bank. :thumbup:

Personal experience. The longer it takes to kill the better the kill.

That's a truism in my experience as well; I'll second this and add that my own impatience typically gets me in trouble (damage to desired turf) more often than does lack of efficacy on the part of herbicides. There was a time I was spot spraying up to 3 times a month and, when things were really outta control (before I "101"-learned up on pre-emerges) and light use of marking dye helped keep me from turning in circles ("Did I get that patch over there? Now, what about over here? Achhhhh!" Most know, or at least can remember, that drill
The other thing I learned (had to learn, even though I was warned) was to back off on use of any broad leaf herbicides containing ester once turf becomes stressed (whether heat, cold, under- or over- irrigation). In fact, my hard lesson came one Fall when I went after some fast-spreading clover with SpeedZone (IIRC) and that night there was a hard frost totally NOT forecasted. LOL, that's when I learned "stress is stress is stress" with my own lawn, at least.
Best o' Success!

First year working on the lawn I sprayed probably 5-6 times, as clover, dandelion, and crabgrass were everywhere. Last year probably sprayed 4 times, and this year I've sprayed twice only because chickweed doesn't go down without a fight.

As said above, just make sure you are waiting at least 10 days in between applications, and don't spray during drought or heat stress. Your desirable turf will take a beating otherwise.

I use the Hi-Yield turflon ester. For spot spraying I use 7cc's per gallon when temps are cooler and above 80's I cut it in half. À gallon jug will make over 500 gallons.

For wild violets spray every 10 to 14 days until they are brown and crispy. They are really tough to kill. Once you have it down to just a few the best method is to use a small hobby paint brush and paint each leaf with straight glyphosate which is a one time kill. Keep your eye out for them because they will pop back up.

I had plenty of chickweed but I think I got most of it. The problem is we haven't had much a a spring. It's gonna be over ninety today. Since the original post there has been more shrinkage. If we ever get some mild weather again I will go out again. :roll:
Thank you for all the replies.
