Just wanted to share my results with using Fusilade II on my turf. I have an empire zoysia lawn, but had some Bermuda creeping in. Found that using Fusilade II will help eliminate Bermuda from my zoysia turf with little harm to the zoysia. Boy was that wrong, I used the absolute minimum rate and it has harmed the zoysia just as much as the Bermuda. It really has stunted and almost killed everything it has touched. The first picture is right before I applied about a week ago, and the one below is what it looks like today. I just hope my zoysia can recover :x :x

Report back in a few weeks with photos of the zoysia and the control of the Bermuda.

Did you use NIS or COC?

Used a non ionic surfactant. Really bums me out that it hit my yard so hard. I would hate to see what happens when people mix it at the suggested rate... which is about triple the amount I used.

Asking because I'm ignorant, but could the areas that are visibly affected be the Bermuda that's dying off, and showing where the zoysia needs to fill in?

I sprayed a friend's yard(St. Aug/Centipede mix) with Avenue South and it really opened up some bare areas, which used to be covered in dollar spot and various other broadleaves. Next up is crabgrass.

I read an article previously that said you should mix triclopyr with either fusillade or acclaim to lessen the injury to zoysia (or TTTF). The control of bermuda increased as well if I recall correctly.

I wish that was the case. I didn't do a blanket spray... thank god. It just really beat the hell out of everything. Oh well, we live and we learn, right?

man that is a bummer. hope your zoysia recovers quickly

@Colonel K0rn,

Do you have a post that goes over the Avenue South app on your friend's yard? I've got St. Augustine mixed with Bermuda. The St. Augustine's lack of resilience combined with the Bermuda's unwavering attempt at world dominance, has brought me to accept both being in my lawn and pamper the St. Augustine more.

I'd really like more info on eliminating the Bermuda. It's always been my understanding that you can really only suppress Bermuda and not completely eliminate it without killing off the St. Augustine.

How did you measure out the Fusilade II? A friend of mine is broadcast spraying Fusilade II monthly to control the encroaching Bermuda in his Zoysia lawn (rates outlined in the TN publication above). He applies 1oz in 12g of water over his 10K lawn. If he over applies in one spot, the Zoysia is yellow for 5-6 days. It would be extremely difficult to measure out the amount needed for a minimum rate spot spray application, not to mention, getting an accurate application without a precisely calibrated sprayer.

Agree, I think blanket spraying with a very well calibrated setup would be the best course of action.

Fusilade II is technically not labeled for residential lawns. One of the reasons is that Syngenta did not want the liability arising from misapplication. Do not feel bad about burning out spots in the lawn with it. I have known people in the business with the same problem. They tried to "spot spray" rather than apply the 4 oz per acre equivalent through calibrated equipment. I use it all the time to remove contamination by Bermuda and Seashore Paspalum from Zoysia lawns. No problems. It is combined with 32 oz per acre of Turflon Ester or else Triclopyr Ester. Triclopyr really helps to mitigate adverse effects on Zoysia while increasing effect on the contaminating grasses.

I measured out .2 oz for 2,000 sq ft to help treat the areas with some bermuda. My lawn is about 10,000 sq feet. I just had a little of bermuda mixed in, but figured that it was about 20% of my yard. I just had no idea spot spraying with Fusilade II was really not a good thing to do. I just never had any adverse results this bad when spot spraying with other herbicides.

I don't have a post, but I can make one. :thumbup:

0.75 oz per gallon is the rate used for nuking grass emerged in tolerant broadleaf ornamentals. If you applied a gallon of this mix per 1000 sq ft, that would be 8X, I repeat 8X what the rate is per acre for selective control of Bermuda in Zoysia. 0.2 oz is still 2X of what label rate is. The fact that you did not tank mix with Triclopyr made it that much worse. I know where I have overlapped with the boom too much because that appears as a streak in the grass that starts out purple, then turns yellow, and maybe some brown. Fusilade does not give much margin for error.

From your experience, how long does it take for the zoysia to wake back up and recover? The zoysia looks ok, but just isnt growing where I have sprayed.

@Greendoc
@Ware

This is 1 week since applying Fusilade. Any idea when the stunted zoysia will start growing again?

 

[Greendoc]

It is going to take a month or two to look ok again. I remember torching lawns with Fusilade before I learned about tank mixing it with Triclopyr Ester. The whole lawn showed brown blades of grass and the rest was stunted.

@Greendoc how'd u s'plain that one ?

Former Neighbor I inherited mine from ended up killing his Zoysia I heard trying to manage bermuda from an 'arcitects' haphazard removal to put on zeon.

 

[Greendoc]

I do not rely on architects to be turfgrass agronomists. I have run into a number of them in town that have had to be corrected on why you do not try to grow Zoysia in deep shade or where reel mowers cannot or will not be used. I have also had to stop them from topdressing turf with straight organic matter. We have clay soils with over 5% OM already.
