Anyone else having problems, it's been close to 90 or over for a while now and I have a couple clients where nutsedge is going like crazy. I'm hoping it cools down a bit soon so I can spray it but it seems like this year nutsedge is going out of control almost every client and neighbor has it.

Yup just keep educating the customers. Yes its an eysore but manageable under the right conditions and it is annual.

I haven't (admittedly) read up on this pest as much as I should have. It's hot here, too. I'm spraying yellow nutsedge, currently. But, it's only in a secluded spot that's pretty hearty.
I know (at least here) it likes moisture. Luckily, the accounts I have it in are experiencing "acceptable" levels.

We use Surge in the warmer weather. The sulfentrazone suppresses nutsedge. We spray crabgrass with Solitare, so we hit the nutsedge again with that. It has a high % of sulfentrazone so the double hit shuts it down good. We used to use Sedgehammer, but it is more of a pain to have another backpack with that in it too, since we need one for Solitare, one for Round up, & one for Perimeter Insect Protection.
I was going to pick up surge the next time I was at lesco because it's states that it can be used to 90, I've been using q4 or momentum fx2 with good results but when the temps reach 80 sometimes it burns the grass and 85 I won't spray it. I keep telling customers why I can't spray and sometimes I think the nutsedge bothers me more then my customers. I hope the temps go down alittle in the next 2 weeks.

does the temperature need to be under a certain temp to use sedgehammer?

I would not want to even walk on a lawn >90 degrees, let alone put water or chemicals on it above that temp.

We use Sedgehammer. For us it has done wonders. Temperature has never been a proble--hot or mild. We only spot spray nutsedge.

It is probably our biggest turf weed here in AZ. here is what I have learned. Prior to the summer solstice, around the 4th of July, the plant the is using stored starches in the nut to put out new growth. It is not taking in or storing starches so the more expensive true kill products like certantee or sedge-hammer do not work. After the solstice begins the plant begins storing up for next year so thats when these products work best as the chemicals are taken into the roots and nut so the chem's can do their thing.
So prior to solstice any product that knocks it down is a good thing. Our local research says a combo of Image and MSMA works best.
The temperature issue I believe is because of use on cool season grasses like Rye and Fescue. It will probably burn those varieties at the higher temperature's. Although I have noticed we have better success when we spray first thing in the morning when its below 100

This is good to know. We switched from Sedgehammer to Certainty this year due to poor results with the former. I think the poor results were because that is what we have been using the last few years and it was time for a change.The nutgrass seemed to be drinking it like Kool-Aid. We've been using Certainty since the nutgrass first emerged back in the spring. We've had very good results up to this point. According to your info, results should be outstanding from here on out...

unless i missed it Solitare doesnt mention heat except when it talks about surfactants. its says not to use sufactants because they can cause discoloration of turf...no mention of temp restrictions on the solitare alone. anyone had problems with solitare in the heat?
Honestly..... you never want to apply any chemical that you do not understand how it works. 1st educate yourself on the product and then educate your customer on the product. This is best for achieving the customers expectations.. the more they understand the better you look to them as the service provider.
Basic rule::: never apply a chemical when conditions are 1) Dry(non irrigated / no rainfall expected for 3 + days 2) Heat above 85 deg.
3) Applicator is unsure of the product use.
Perception is one of the best tools you can use and its FREE !

We love using gly on blue grass when its 95 plus F. It works so well p.s be sure to add li700 also 4 pints per acre.

If I had to wait for temps below 85 we couldn't spray from March-Nov. :laugh:

Yeah it's a different world down there. Up North we try & stop spraying around 85 so we don't hurt our Northern grasses.
i had that in few yards last year. I used sedgehammer, but it did not do anything. Expensive as hell too. I think i paid $20 for one oz or something like that. I was very, very dissapointed.
this year it's back again and i am just wondering what to apply. Can't do roundup since it's now in the grass area as well.
I hate this weed. More so than crabgrass, since i can't control it.

Put round up on a sponge and wipe in on the sedge

Sedgehammer works very well...(with a non ionic surfactant) you got to hit the sedge at the right time... right at about 2-3 buds on it, even then you'll have to go back a couple of times. Once it grows too mature you are throwing your money away. Mow it down & when it starts budding again, then hit it.i had that in few yards last year. I used sedgehammer, but it did not do anything.

By the way, carefully reading the label helps, and looking up nutsedge at you local extension web site will teach you the characteristics of this pervasive weed so you can better understand how to control it.
As far as turf applications are concerned, I would avoid treatments when it's much over 85 degrees or likely to be in the next day or so. This will be an area of contention here. I only spray Celsius when it's above 85, but it won't help you for sedge.
I'd actually like to know what to use on wild onion & wild garlic.
