In my area we have had a lot of cool weather and for the 1st time in several years, rain. I am seeing a lot of brown patch which I feel the conditions are contributing to this. Is anyone seeing this and if so what is your approach? Wait it out till temps take care of it or start treating? As I've mentioned it in the past I like dry conditions since most of my customers that have irrigation and you can control the water vs mother nature.
I am seeing it in allot of places as well. I think we might be seeing more with this kind of cool wet weather but hopefully not. According on the customer we either start treating to try and stop it and the bad area we replace. Then we have some that don't want to be treated just the dead spots replaced.

Ar,
Yes, here in Jonesboro, we are starting to see quite a number of lawns coming out of dormancy with what appears to be Brown patch fungus. It has been cool here and totally wet. Temps have soared up to 80+ then at night down to 45. Greenup has been awesome and other things coming into season faster than normal. However, I see no need to control this fungus as long as the conditions impair me from getting product down. Heritage, Banner max and such products is way too expensive to just throw around on unstable weather conditions. I hope that this weather snap will end soon and get some product down to stop the spread. I plan on using......Cleary's and wait till hot weather before applying fertilizer.

I agree about the fert. I haven't put any down yet and customers are getting antsy. Of course the DIY's have put it down way back in March. I'm fairly new to disease treatment but as I understand it N will only encourage brown patch, correct. I did read a thread in which Ric mentioned he can usually "outgrow" BP. Not sure exactly what he meant by that?
The disease problems flared up here just over 2 weeks ago when we had the 3 days of 85-88 degrees with high humidity. It has since gone inactive with the slightly cooler days but the damage it left behind is still evident, even though slight.
I have had both Pythium and Large Patch(for years we called it brown patch) in some of my Zoysias. Confirmed by UofA Lab
We have about a 21 day window and I figure the heat and humidity will be back soon so I applied fungicide Monday and Tuesday this week to 5 or 6 lawns.
Apparently, other LCO's in town are having a bit more trouble with it. They've been applying too much N to lawns and know it(have even admitted it to me and some of their customers). I've picked up a handful of their former customers who have been fighting disease problems for the last few years with expensive fungicide apps from their former lawn care providers. To say they're upset is an understatement

Yea, I'm aware of the 2lbs N per year recommendation on Zoysia and I totally agree with you on the wait for first fertility even though I run it a month or so ahead of you (remember,I am south of you) However, I do not hit them with a full pound of N per app. I apply 1/2 pound of N per app. Hitting them with anything over 3/4 pound N in one app has always caused problems for me. In the grand scheme of things my fungicide expense for disease issues in turf is pretty negligible when compared to Gross Revenue. I really think it has a lot to do with my approach to fertility in zoysia, which is more prone to disease in our area.
What exactly is the difference between Brown & Large patch? I was thinking they are pretty close to the same condition. The fungicide labels seem to group them together.

Well the real problem with Zoysia is that nobody mows it properly. It's waaaay too tall then it gets slammed with disease.
Our fairways at our golf course are Zoysia and they never have any issues and they only get two fertilities per year,a grub control and that's it. Of course they are reel mowed.

I agree, they aren't mowed properly. Most do not scalp them in the spring like they should and then mow them too high with a dull blade the rest of the season. Add poor irrigation practices on top of that and all you need is to apply too much N through the year and you've got the makings of an ongoing disaster.
Some will get disease no matter what but much of it could be avoided by proper cultural practices by the customer and proper fertility practices by LCO's.
For the most part I have not done Lime apps the last 2 yrs. Dr. Boyd has mentioned in several of the last few classes I've attended that diseases don't do well in lower PH. I used to push toward 7.0. Most of my lawns are in the 6.2-6.5 range and unless PH is 6 or below I no longer apply Lime. Another thing he has mentioned is aeration in the fight against disease. I am now pushing aeration especially on those with past disease issues.
All I know is that disease issues for us are pretty low for the most part and according to my competition, running rampant for them. I've been told they spent 10's of thousands on fungicides last year. I spent less than a thousand. In relation to our compared business size, their budget is way out of wack. Maybe I'm just lucky...or maybe I'm doing something right. I'm not sure.
Ted, I was talking in generalities about Zoysia fertility, not really to you.
We put out 2 fert apps at 1lb on those approx dates with 50% slow release. It's worked great for us. We push aeration hard. Some just wont do it. Oh well. We charge about 1.5 times our app price to aerate. I'm thinking about getting a ride on and pushing for more volume at a little lower price.

We charge the same as you do for aeration. My primary competitor charges 2x lawn price.
I've considered a tow behind model but can't justify a couple more thousand for it after just buying the XT5 last year and it isn't even really broken in yet.
I already have the hitch foot plate for my JR 36 so if I do buy a tow behind I'll be ready to go with it. It'd be nice to be able to do large areas quickly.
There's definitely no way I can justify a ride-on aerator. I haven't heard anyone say anything about the Exmark and I have no idea where that stands since they took over the Lawn Solutions design/model.

I don't recommend a tow behind unless you have wide open areas. I have one and tried to use it but it was too inconvenient to use on my customer's lawns. If you are interested it is for sale, prob haven't used it 10 times.
My fellow Arkansan's,
Does the state do your disease detection for free?
I was told by my extension agent that the cost is around 125.00 dollars.
It seems likely that the customer isn't wanting to pay this fee, however the loss to turfgrass will exceed this amount.

Weed ID...Free. Disease ID...Free. General Soil Sample/Analysis...Free
Here's where it gets out of hand as far as their charges...Nematode Detection/ID...$10.00. I think they have to charge you for that one because they not only detect and identify but they actually have to do a head count on the pathogen to determine severity.
I paid that fee myself one time. It was worth it to get that monkey off my back.
...Maybe your extension agent is hoping you'll pay cash. :laugh:
I've heard the extension offices "vary" from county to county(if you know what I mean)
Ours here in Faulkner County is awesome. I'm sure your office deals mostly with Rice, Soy Beans and Cotton due to your area being heavy in field crops.
We have our share of Rice and Beans grown here(not nearly as much as you) but we also have several orchards, and a strong Master Gardener program. It's only been 7 or 8 yrs now that our office has really started being a good rescource for us in Lawn Care. They work hard to get us classes and workshops dealing with turfgrass and when we have questions, they are quick to get back with us with answers.
Good luck trying to get an agent to help you in my area. They never get back to you.
" If you have a problem check with your local extension agent" De loca check you local agent agent:laugh: (George Lopez)
