3 way + Drive = dead lawn

Has anyone mixed Lesco three way (at 2 ounces/gallon) and Drive 75 (1 ounce/3 gallons) and then did an application, only to find that it also killed the turf grass around the weed?

Temperature at the time of the application was around 80. On one lawn, we treated for crabgrass and virginia buttonweed. The customer called two days later and said that her lawn was spotted. We came back and every area we sprayed was dead!

Just wanting to see if anyone has had like experiences.

 

Just a thought, but isn't 80 a bit hot for an ester? Perhaps an amine would be better, also, if Drive is labelled for the broadleaves you are after, why tank mix?

What time? What is the sun like? What sticker did you use? Drive calls for MSO only, although I use regular sticker from time to time with limited results.

EG

 

Should have used Speed Zone. I'm not sure why you'd apply Drive this late in the season. As for the dead lawn sounds like you laid it down way to hot. Hot as in outside temps and oz. per gal/k.

 

Sounds like you sprayed the weeds a little too heavily. We tank-mix Drive and Battleship for spot-spraying. No problems, even in higher temperatures, except for with new applicators who try to drown the weeds.

 

I guess my question, would be, instead of Lesco three way (at 2 ounces/gallon) and Drive 75 (1 ounce/3 gallons),


how many oz of each per 1000sqft was put down.

You may tank mix it right but is your application rate right?

I also mix drive and Battleship for spot spraying.

 

Lesco 3-Way max rate is 1.5 oz/M. Drive goes out at 1 lb/A and must have a methylated seed oil added. Others can be used but may get phototoxicity.

 

Can you explain what Battleship is???????????

Thank you,

Try using confront on va button weed seems to work great .had good results in 80s and 90s temps.button weed and nut sedge going crazy here with all this rain we are having.

 

Battleship isnt new chemistry. It's the actives of Confront, (triclopyr and clopyralid) blended with mcpa. Your looking at a non 24d based product.

57% inert ingrediant
37.9% mcpa
3.8% tric
1.3% clop

If your looking for a non 24d product. I like Eliminate from Lesco. You get the benefit of Dicamba which I feel does a better job for summer and fall weeds than Clopyralid. Plus your not buying as much inert ingrediant.

40.69% inert
48.99% mcpa
5.59% tric
4.82% dica

But thats my opinion, and like everybody else we all have one.

 

Confront and VA Buttonweed?

Sounds like a plan to me, we have it everywhere along with the lespedeza, which Millenium work ok on, but I had to use a high rate and it burnt the turf a bit....Well maybe more than a bit, but I warned them....

I will get some tomorrow and try it out.

Thanks!
