I was over at my mother in laws house today and noticed their bermuda lawn was overcome with weeds of various types. I told her that I would spray her lawn if she wanted and she told me that her husband had a 6 gallon sprayer, but that he couldn't physically do the spraying. I didn't like the sprayer and know I would just use my own, but she showed me a 2.5 gallon jug of Drexel MSMA 6 Plus with surfactant that they had. She told me I could have some as they would never use it all. I plan to lay down some prodiamine and use the MSMA on their lawn.

However, I have used prodiamine and Celsius on my yard and there are literally no weeds to be found. It took a few weeks for the Celsius to do the job, but do the job it did. Would there be any benefit to using MSMA on my lawn instead of Celsius and are there any dangers in using MSMA like discoloration/burning/etc.? Does it work immediately or need time like Celsius? I haven't even opened the Certainty as the Celsius knocked everything out.

Celsius won't do anything for nutgrass or other sedges, dallisgrass, etc. so you still might need the Certainty or MSMA if you see any of that pop up.

Dallisgrass is really the only weed that the Celsius/Certainty combo won't take care of. MSMA will burn at 90* plus temps, but is relatively safe below that. Best advice would be to use the full rate of 2 oz/gal at 80 and work down to 1 oz/gal at 90. Be careful with spot spraying as the application rate tends to be higher than intended.

Thanks guys. Has anybody mixed prodiamine and MSMA together? Thought maybe could spray the mixture 24 hours before expected rain as they don't have an irrigation system.

Should be fine. I've mixed it with Pendimethalin and it didn't have any problems. MSMA does great on grassy weeds but doesn't get many of the broadleaf weeds.

On a side note are you at all worried about working with the MSMA? I usually use eye protection long sleeves, long pants, shoes, latex gloves and a P100 rated gas mask. Any tips or am I being overly paranoid?

 

[J_nick]

I keep the kids off of it till I can wash it off the grass. As for me I might have a pair of sunglasses on.

Haha, true.

Reviving an old thread due to some new questions:

I still haven't used the MSMA, but after a Prodiamine app this spring and a summer app of Celsius/Certainty, I have some spurge popping up as well as some goose grass on the south end where the lawn struggles a bit.

I'm not sure why the Prodiamine and Celsius combo didn't handle the Spurge so I was thinking about trying MSMA instead.

Tomorrow will be a high of 92 with no rain. With herbicides do you only worry about temp at time of application? Could I apply it tomorrow evening when it gets in the mid 80's and not worry about damaging the grass. The label says yellowing might occur irregardless of temperature....what are people's experience with MSMA and chlorosis/yellowing?

Or should I just spray Celsius again? I hate the time it takes to kill it though.

The temp for the next several days needs to be accounted for, not just the temp at application.

Without knowing the tolerance of Zorro, I would mix a very light dose (.5 oz in 1 gallon) and spot spray a small area. If it is going to cause yellowing or injury, it will probably show in 3-4 days or sooner.

I wouldn't call MSMA a quick kill, it's not Glyphosate (Roundup). The Goosegrass may take a couple applications depending on how strong you mix the MSMA.....fyi.

 

[Jacob_S]

I must have weak dallisgrass cause celsius did quite a number on it when used at high rate and two apps about a month apart. And by did a number I mean its gone.

On domyown com it says MSMA is not for residential lawns what gives.

MSMA isn't labeled for residential use.
Policy changed in 2009, went into effect in 2011 I think. Thank the EPA.

I think this is essentially on hold, but will be reevaluated again next year IIRC.

The re evaluation is to determine whether golf courses will still be allowed to spot spray 100 sq ft out of an entire acre. I have a hard time believing that label is being followed when it is still being made and sold by the pallet. 100 sq ft x 18 holes would barely be 2,000 sq ft. No one needs a 2 1/2 gallon bottle if that is being done. Try more like a quart at a time. The entire accusation is BS anyway. It started just because golf courses in Florida were spraying it during the summer rain season.

Can't it still be used for road-side/fence line management or am I just guessing on that one?

Doesn't it have something to do with Organic Arsenic vs Inorganic Arsenic. Apparently that word strikes fear in everyone due to the stories of poisoning.
