Re: Yellow Lines On Grass

I see that often. My guess is where you are it’s hot, it’s dry, you rolled several hundred pound mower over it. Don’t do that. Buy one of these (or a better one if you can spend the money): https://www.amazon.com/dp/B00NTPVHOG/ref=cm_sw_em_r_mt_dp_U_OUInDbJPDWAAY Pour on the water until you get mois...

Re: Figuring out rainbird 5000

You need to test your system. They call it distribution uniformity or DU and precipitation rate or pr. I’d set catch cups in each zone in turn, including any noticeable dry areas and run it for 30 minutes. Measure what’s in each cup. For any outliers, your DU isn’t good. Figure out why and fix it. Y...

Re: Ferrous Ammonium Sulfate | Liquid Iron for Lawns

Don’t forget temp affects uptake. Hotter means more uptake. Hmm..I tried googling for this and couldn't find anything. The only thing related to temperature I can find is the common advice of not applying in high temps because it can be phytotoxic. Is that what you meant, or have you found/read tha...

Re: Fungus ID thread

tgreen , great info, thanks. From what you’ve said, sounds like despite the $$$, GLS is sufficiently bad that it’s a necessary expense. The SDHI’s are very promising, but so new seems they’re not yet well characterized for how they exactly work on what, especially in terms of resistance and rotatio...

Re: Howard Johnson's T-Methyl Granular Fungicide

Well, here’s another way of looking at things. It’s mid-July and for mid-July your turf looks pretty good. You’ll never prevent all fungus without a golf course superintendent’s budget (and often not even then). Don’t really know NJ but bottom line here is keep it alive over the Summer. For looks, s...

Re: Howard Johnson's T-Methyl Granular Fungicide

Another approach is to apply the Tmethyl at curative rate and observe the response. If it doesn’t improve (improvement meaning it stops getting worse — fungicides won’t fix what’s already damaged) you then know 1) likely not GLS and 2) whatever it is, Tmethyl not effective on it. A lot of folks don’...

Lesco 24-0-11. A bit more than half of the N is soluble (uncoated urea). Has been working well for me.

Re: Bermuda suppression (removal) from TTTF

I’m also working on ridding my lawn of bermuda but I have less bermuda than you do. In addition to the pylex / triclopyr routine I’ve noticed that a tall, dense healthy stand of fescue helps to shade bermuda regrowth. Seems to make the herbicides more effective and it may just end up a matter of att...

Re: Fungus ID thread

Wondering if anyone can shed light on this. I can’t tell if my dog had been going in a place he doesn’t usually go, or if I have something else going on. My suspicion is brown patch. Lawn has been on a pretty regular fungicide plan. TM 4.5 was applied approximately 11 days ago. This popped up in a ...

Re: Bermuda control with Pylex and triclopyr.

Here’s the actual plant — toast. There are still live sprigs but the ones I hit are so toasted, I have to assume I missed the healthy looking ones.

Re: Bermuda control with Pylex and triclopyr.

I think I'm about to try my first Pylex application. A little concerned about the stress on my existing turf though.... Any pointers for preparing for this? My wife will kill me if I nuke part of the front yard to kill a dozen runners of zoysia and bermuda. I’m new at it too but I can say what my s...

Re: Seed sitting on lawn

Sorry my friend but no experience with warm season. For cool season at least, it takes very little water to start germinating and it will grow a surprising amount of root without water thereafter until it dies if it meets only dry. What I’m getting at is if it rains to start germination, gets dry bu...

Re: Fungus ID thread

It is nearly impossible to positively ID fungus (or lack thereof) from pictures. Most PHD turf pathologists won't positively ID it without putting it under a microscope. Everyone here, including me, is mostly guessing. Sometimes, it's easy like rust in the fall but for the important diseases it's n...

Re: Bermuda control with Pylex and triclopyr.

Has anyone used triclopyr alone (without pylex) to remove bermuda from TF? I talked to a guy today that told me the guys he sells to use triclopyr alone. The label says bermuda "suppression" at 3/4 oz/k for 4 times at 4 week interval. I'm trying to help a guy who is not interested in $500 for the b...

Re: 'Perfect Blend Lawn Food' Lowes version of Milorganite?

I believe Milorganite is banned in Maryland. Have you read the fine print in ingredients label? It lists lead, a toxic heavy metal, and it also says it is great for gardens. Talk about an oxymoron. I used to put Milorganite on lawn at owner's request, but once read up on "Toxic Sludge is Good For Y...

Most of the bermuda looks absolutely smoked, like just totally dead, brown, shriveled. In those areas, no bermuda sprigs aliv...
