Have a few nutsedge heads left coming up, but not enough to use the whole 0.9 packet that makes the gallon so all I need to do is spot spray. Question is, if I mix it up, leave in sprayer will it go bad and I can just spot spray what I see over the course of the next month?

Also, one other question now that I think of it. 20% chance of T-Storms all week so how long after spraying does it need before rain? I'm assuming same as before mowing; 2 days? :confused:

Thanks guys and ladies

I have a designated sprayer that I keep mine mixed in, and it sits for a month or so at a time and works just fine. It has to be re-shaken well, but works all the same.

Kirk,
If you are planning on mixing up a gallon with 0.9 grams-- why not do it in another container and purchase a little quart spritzer sprayer and exchange your small amount to it.
If you don't need a whole gallon--I have used spritzer bottles such as windex bottles for light doses. The seals aren't that great but after use.......triple rinse them out and store them for late. The other part of the gallon can be used too.

its rainfast in three to four hours - it's right on the label.

I would shake it up, if it sits for awhile, before spraying.

remember to add 1/3 ounce surfactant.

Nice, should be able to get some done tonight.

Yea, have the surfactant on hand just for this. :drinkup:

Nice idea TG

And with a spray bottle your not going to waste as much as a wide spray nozzle would apply. Wish I had thought of that earlier one packet would have done the whole yard :laugh:

LOL...Didn't see the second part of the question...I was WONDering where the rainfast came into the relevance! :)

Mixed and sprayed tonight, not much to spray and used about a quart but the backyard was mown a couple days ago so give it 2 or 3 days I might have some more popping up back there.

No guarantee it will be good after a few days. Small quantities are difficult. So take your tiny packet of Sedgehammer and pour it out on a paper plate and divide it into four equal piles. Use each one to mix up a quart. Mark it carefully and seal in small plastic bag. Staple to label. Do not separate the label and cautions from the chemical! That is dangerous and illegal.

I am a little surprised at you post if you mean "SEDGEHAMMER". My experience is just the opposite and it goes bad with in a day or so. I know the pH of water will effect Sedgehammer and I add Baking Soda to raise my pH.

I am like you in keeping designated Back Packs. They save time and allow you to do better work.

Yeah, So far, it seems to have worked without trouble. Granted, some aps have to be repeated with a little new growth, but it seems to do alright. I have no idea if light breaks this stuff down or not, but I keep all my sprayers (all) covered. Also, on a sidenote, I haven't used actual Sedgehammer yet. This is still some Manage I have left over. I scooped up on a bunch real cheap - what my JDL had left over laying around when they were phasing it out. I know it's irrelevant, as it is the same thing, but just thought I'd mention it as kind of a cool little thing. :) While all my bp sprayers are designated for many different aps, I only use a small 1 gal. sprayer for the nutsedge treatment, because I just don't get enough of it to mix anything larger.

Nice idea keeping it covered and keep it from light exposure. I put mine in my shed so I might go ahead and put a box over top of it or a towel.

Used about a quart of the gallon last night but I mowed the back a few days ago so might take a little longer for anything back there to pop up but the front was mowed a few days earlier then the back.

And you never had to repeat a apply where you mixed the Herbicides Fresh??? Let us face it Sedge is not an easy one time kill. I am glad Sedgehammer stays good for you. Covering it from UV light may be key to your success.

Does anyone have any actual scientific data on the decay of Sedgehammer after it is mixed? This is one of the mysterys of our industry. The label won't tell you and The manufacturer would rather see you mix a new batch (naturally).

Has anybody compared week old and newly mixed Sedgehammer on a side-by-side basis on real nutsedge?

Runner is an older respected member and trusted source of information here on LS. That why I was so surprised at his state about weeks old Sedgehammer mix being still good. I am not saying he is wrong just doing something I am not. In this case maybe it is the UV light.

I seem to remember Groundskper years ago posting something about Manage (Former Name of Sedgehammer) and the tank life of it. I have send Groundskper an E mail to see if he remembers that post. I would love to tank Sedgehammer and have it good for a week at a time instead of Hours I now get.

I mentioned this in another post on the same subject a couple of months back.

I had almost 2 gallons of pre mixed sedgehammer/manage leftover from last fall that I stored in my garage over the winter. It is well insulated but "not" heated. I used it this spring (roughly 7 month old mix) when nutsedge first appeared and it worked as if it were mixed that morning.

In all the years that I have used sedgehammer/manage, I have never had a problem with it "going bad". Depending upon how much I need to spray, most of the time my mix will sit for 3 or 4 days before I need to make up another batch.

My truck is open, so the sunlight is on it all day. I also use a marker dye, which I am sure helps.

Bottom line...if it sits for a few days you should not have any problems, and as mentioned above, make sure your pH in your water is up to par.

Thank, I learned something today and I hope I can learn something every day.
