    Hi Folks,

    Just wanted to get some thoughts and ideas from some of you on collar/green surround areas. Our temperatures have been 100+ with little to no rainfall the past couple weeks. Currently its still very warm (90s) with little to no rain. We are experiencing problems with our collars and aprons looking very poor (they look dry/brown/patchy, however, have plenty of moisture in the soil profile.) We don't suspect any disease activity (fungicide apps are controlling the rest of the golf course).

    Any ideas?

    I would believe this is mostly heat stress/damage, and have heard of guys needle tining collars and aprons to vent and allow the soil temperature to drop quicker (overnight?) and reduce damage. Does anybody have any experience with this as far as timing the aerification? (Is this typically something you do prior to heat?) (Has anyone tried it during the "heat" of battle?!)

    Greens, Tees, Fairways seem to be pretty good given the heat/rain (or lack there of) situation that I'm sure most of you are experiencing at well. Wetting agent has also gone out on collars/aprons a little while go.

    I hope this post makes sense I feel like I've been rambling...

    Thanks everyone!

    Bob (from central Iowa)

    Bob,

    In the mid-Atlantic, I saw the same poor collars and finally stuck a knife in them and discovered ABW grubs. I'm not sure if you have them in Iowa though.

    Bob,

    Hunting billbugs have become an issue on zoysia here in Missouri. Just something else to look for.

    We've got a couple of zoysia approaches and collars looking a little pale, even after fertilizing not long ago. I'm going to check for some billbugs, but also I think part of our issue is traffic. We have normally in the past slice open our zoysia a couple of times over the summer, have only done it once this year.

    We have spiked them with a triplex spiker in the past as well, but the spiker hasn't found it's way north from one of our other courses. We tried aerating them before as well, and let's say it was so hard that we didn't get one collar poked. Will look at different tine material next time we try it.

    Having same issues here in southern Minnesota. I am positive it isn't grubs though. I have been out handwatering but no success. I have aerafied and spiked and nothing seemed to work. I am assuming it is just the heat and stress from greens mowers turning on them, even though they are taught and told many times not to. I just went out on Monday and overeseeded the spots, may have to resod.

    I am not sure if it is feasible for you but turn boards tend to aid in the stress on collars. raise the HOC, needle tine, top dress and flood them whenever you are on a green watering. This worked for me in the past on similar conditions.

    Bob,

    You're not alone my friend, seeing the same here in Chicago and was confirmed by USGA agronomist that more around the area are battling the same. I posted this exact situation a few weeks back and got somee great information that we implemented. I'm sure somee of my issues are due to just gassing and regrassing last fall but do feel the heat, drought, and mechanical use are adding to the mix. Recommendations I received were to lower mowing height, not to topdress, add small amounts of organic fert, and reduce mechanical traffic. Our collars are PennEagleII/PennLinksII and we were mowing at .300. Since my post we have lowered our height to .275, started topdressing greens by hand to control sand better, done dropspreader applications of organic fert, and expanded our use of plastic lattice not only on the approach for turning but completely around the green to keep mowers from directly being on collar. We have seen some slight progress, not seeing things get worse at least. If we can just get through these next few weeks I think we'll be home free and recovery will be implemented. We plan on aerifying probably 2-3 time this fall and again next spring, overseed where necessary. USGA also said where most cases are taking place is where the approach narrows and transitions into the collars, again I stress to my guys to use the lattice and stop turning directly on the bentgrass. Just looked over the Steve McDonald article, good read, very similar info that I just wrote. Here are a few pictures of what we were going through and then how things looked a week after we implemented somee practice changes.

    Bob,

    We are experiencing the same thing. Our collars, tees, and fairways have a lot of Poa in them...well at least they did. Bad thing is it checks out whenever it gets hot, good thing is that is always comes back in Aug/Sept. My biggest concern is our greens. Never before have we had so much localized dry spot, we have tried numerous wetting agents and have been hand watering daily. Nothing seems to be working. My conclusion at this point is either it's severely hydrophobic soils or it's just too d*** hot here to recover no matter what we do. It's hard to look at the course right now, this is the worst it has ever looked, hopefully everything will come back. Not to mention, out only source of water is our pond, and it's getting really low, so I can't water as much as I need to...Hang in there!

    Just too add another here in Chicago at our course we are having the same battle. Greens, tees, fairways, bent looks fine doing well, Poa on the other hand is under stress beyond belief! We are hand watering utilizing every hose, greens utilizing wetting agents, still having hard time getting poa to be happy! I am from Mid Atlantic and have seen this before, but not here in Mid West! It will be soon time to plant bentgrass and the opportunity to push more bent in these areas is coming, so we just keep the hose going and pray for relief and seeding time soon! I believe it just comes down to soil temperature being so high now at the surface where the poa rootzone is! JMO

    Nicholas,

    You have made a perfect point. All these posts about putting down "boards", or whatever, to protect the collars from employees spinning their walk mowers, in what I assume is a "perfect" 180 degree turn (there's no gold medal for that), are troubling.

    Get your operators to go where needed, even if it's 10 feet off the green, then turn. If you happen to be mowing in a direction headed right to a green-side bunker, then they can "walk" the machine down that strip to an area where they can turn.

    How much time are we talking about? More than having another employee, or employees, place "turning boards"? That is absurd. I don't care whether we're talking about triplexes or walking mowers. If your turf is stressed, or even if it's not, why would you accept a "zip" turn? Is the intent to knock off two minutes...at most? C'mon...they spend more time than that driving to where they're supposed to empty their buckets!

    Common sense. If the operator sees that the area is "thin", then drive, or walk the machine to an area that is not, before turning. And it doesn't need turn on a dime. That's not smart maintenance, that's just showing off.

    Again, placing down "turning mats?" Unbelievable.

    We are looking for a turning mat salesman. Pays half decent.

    Jeff took himself out of the running.

    where can I find these turning boards? I looked in par aide, eagle one, and standard. Looking for long, lightweight, plastic ones if possible.

    I know some guys use the plastic/vinyl lattice from HD/Lowes. Lightweight and cheap.

    We send all of our greens mowers with small blowers so they can blow off any sand near bunkers that has made its way onto the green. We also do a collar spray every couple weeks with Am. Sulfate and 46-0-0. Typically .25-.3 lbs of N per application. Using only the center boom our spray tech drives in a circle around the green. We prefer to have a green ring around our greens instead of a brown one. We started doing this last season because we were having similar issues from our clean up lap due to the edges of our greens being sloped or sand being ground into our collars/green edges.

    I thought the same thing. Totally Walace advice too.
