GIS 2017 Orlando Florida summary

I’m back from the US from the Golf Industry Show (GIS) in Orlando. I attended as usual the education conference on Monday and Tuesday and then the trade show the other days. My week concluded with a visit to the University of Florida to visit Dr Phil Harmon and Dr Carrie Harmon along with their lab technician Jeremy. I visited the university as we have done some disease diagnosis and resistance testing in the past with them (where I showed resistance in Sydney to the DMI class of fungicides to dollar spot). We discussed issues in the area and compared to Australia QLD is similar with all the warm season grasses.

I was shown around the lab where they take extra protocols with international samples. Everything has to be spot on especially receiving foreign materials. The process is the same as the local samples but the extra care has to be done.One thing I was impressed with is that a simple test is not so simple when the diagnosis becomes difficult and further analysis is done to get an accurate diagnosis for the client. I was also intrigued by all thre parts of the world where samples have been sent from, they truly are an international diagnosis lab.

Myself and the University of Florida team (Phil, Carrie, myself & Jeremy). Thank you so much everyone for taking out the time and look forward to working with you in the future.

I was very active on social media and many of you may have seen the videos of each day I did. If not here they are which give a good summary of the week. I will post more on the education seminars down the track. However if you have any question please don’t hesitate to contact me.

Stats from the show:

13,600 people attended across the week

5800 people went to the education seminars

Whats new?

Well not alot to be honest, but the most exciting thing was the GPS spray units now commonly available. Hopefully we will see these at our show from Jacobsen and Toro.These units will make spaying more efficient and changes on the go will be done in an instance- which will reduce the need to change your nozzles or water pressure all of it is done automatically.

I have been getting a few messages on digital job boards. I was at a presentation during the show from Jason Haines form Canada who i speak to regularly on twitter. He is an expert in this field and runs one for his 9 hole course for 3 staff. It is very simple to setup. For more information visit his digital job board blog www.turfhacker.com

Thank you to everyone who enjoyed my social media posts while I was over there. As well it was great to catch up with friends and make new ones.

 

i will post on the education seminars lately but in the meantime enjoy the pictures form the show.

 

 

 

 

 

 

 

 

 

 

 

 

Heat wave, humid, rain birings on pythium- January 2017

Happy new year everyone I hope you had some time to enjoy with family and friends.

What a start to the year heat waves in Victoria, WA, SA NSW. Storms in QLD and everything in between.

 

Non disease Issues you may face

I have been seeing quite a few sick started to see a few sick turf surfaces around the place just due to sheer pressure from the heat, lack of rain and too much rain. One thing to keep in mind when there has not been alot of rain like especially here in Sydney is to look sodium levels. i have seen this season and in the past poa really going off colour and t

Generally speaking this may not be an issue every year or your water source might be quite low in sodium generally speaking. However this does change over time and has to be monitored. As well having low levels is good but bare in mind putting on a little all the time will build up in the soil and the plant and cause the plant to suffer. Keep this in mind this season, look at an few applications of a product that will reduce sodium levels. Talk to your local rep on this as this issue can be the underlying cause of disease especially pythium..

Another issue you may see is nematodes. Again you may not have a history or testing for them numbers have come back low. However I remember a talk I heard on nematodes from David Westall he always said that the numbers don’t tell the whole story and your threshold may be different to the person down the road.

If your turf is stressed and the root system has shrunken you are more prone to an attack as the plant can’t fight them off naturally.so keep an eye out.

With these conditions you need to look at for the remainder of the summer is your spray program.Normally 3 week intervals are working but with this much pressure you need to look at shortening intervals to 2 weeks. On top of that a in between spray may be needed just to top things with the onset of heavy rains.

The week ahead

Pythium

Pythium is one disease that will be present now.

Water logged greens are a perfect environment for Pythium root rot. You can see Pythium as patterns in greens that follow the drainage lines. Equipment use also spreads the disease. If you have a short root system with compacted soil and poor drainage, your turf will need extra light watering to keep it alive. This will increase Pythium pressure, due to plant wetness. On the other hand, deep infrequent watering can increase Pythium pressure as well as the roots and the soil are being completely soaked which is conducive to Pythium outbreaks. Very hard to win in this situation. That is why it is important to maintain healthy turf and to use specific Pythium fungicides on a preventative basis.

Apply your fungicide (use Proplant here) down past the leaf and crown do not leave on the surface with application (water in slightly after your boom application)

Proplant image

As always we do recommend a broad spectrum tank mix partner with Proplant (as its is specific to pythium only) as when we were anyalysing the samples in the trials we always found other diseases namely brown patch. So have a look at partnering Proplant with Ippon, 250GT, Protak, Monstar,

Also be aware of algae with all the wet surfaces. A good mix is Dacogreen + Liquid Dek here.

Cultural Controls of Pythium:

  • Avoid too much N
  • Aerate the area slightly to allow more oxygen to penetrate the soil
  • Utilise pentrant wetting agents to push the moisture through the profile-I don’t tend to recommend to use with Proplant as it may push past the plant where you need to target the spray
  • Keep plants healthy as possible with using root stimulants and other biological products
  • Avoid mowing in moist hot weather
  • Raise mowing heights
  • Avoid verti cutting, top dressing if greens are infected  as it puts more stress on the plant
  • Reduce leaf wetness
  • Increase air flow and sunlight to Pythium prone areas
  • Reduce sodium levels
  • Monitor for insects

For more information see the brochure here Proplant Brochure Also have a look at our guide to managing pythium not just from a chemical point of view but from a cultural view. Disease guide rhizo eri pythium 2014

I hope this post helps understand the disease a little better and how to manage it.

Also I am heading to to the USA to GIS again and will be attending a few lectures that i will post about later on. You will be able to follow what is going on through my twitter feed.

As usual if you need any help feel free to contact me

Dacogreen WeatherShield “The Ultimate Chlorothalonil”

Some facts you may not be aware of in regards to chlorhthalonil in Australi:

In 1971 (some readers would remember this) Colin Campbell Chemicals introduced chlorothalonil named Daconil into the Australian turf market giving us over 45 years experience. From the initial formulation as a wettable powder, then into a SC (suspension concentrate) and now to the brand new WeatherShield formulation we have always continued research and development into chlorothalonil giving us insight into the working and benefits of this broad spectrum fungicide.

Dacogreen WeatherShield is an evolution of the original Dacogreen/Daconil (chlorothalonil) formulation that been the basis of broad spectrum disease control in the turf industry.

“WeatherShield Technology™”
Dacogreen WeatherShield is a superior surfactant technology.  This technology allows for:

● Improved sticking capability

● Smaller particle size (reduced from 3.5 to 2.5 micron) that spreads evenly for turf protection

● Improved rainfastness over the original Dacogreen 720

● Superior rainfastness over generic chlorothalonil formulations

Two trials were conducted on cucumbers to observe coverage and rainfastness of the following chlorothalanil based products:

  • Dacogreen 720 SC (original formulation)

  • Dacogreen 720 WeatherShield

  • Generic 1 chlorothalonil and

  • Generic 2 chlorothalonil

Cucumber leaves were chosen for the trial as product retention results could be measured more easily than turf leaves. Three replicates were performed for each product

Trial 1 measured the retention of chlorothalonil after simulated rainfall of 40mm of rain over a 2 hour period 1 hour after application. Note, that with this trial the leaves of the plants were not totally dry before rainfall occurred due to slow drying conditions.

Trial 2 measured the retention of chlorothalonil after simulated rainfall of 40mm of rain over a 2 hour period 24 hours after application.  In this instance the leaf of the plant was totally dry before rainfall occurred.

 


 

 

In both trials Dacogreen WeatherShield and Dacogreen original out performed Generic 1 and Generic 2 chlorothaolnil formulations easily for retention of product with more than double the retention. What this means is that using Dacogreen WeatherShield enables you to be confident that Dacogreen WeatherShield will still give you the results desired even with the onset of rain soon after application.

So next time choosing a chlorothalonil product for a broad spectrum disease control have a think about what you are getting and ask for DACOGREEN by Name

Dacogreen WeatherShield is registerd for use in Australia at the following rates

for:

Dollar spot,

13L-20L per hectare

Brown patch (rhizoctonia) 

13L-20L per hectare

Grey leaf spot control. 

24L per hectare

Always read the label before using any product.

High to Extreme Disease Alert Sydney – December 2014

Wow after the driest spring on record and a very dry and hot November December has had a u-turn. high temps high rainfall. This is what I saw yesterday on the radar and on the road. Yes it did get worse after I got home (pic taken by passenger). The red on the radar meant very heavy rain.

 

Radar 3/12 Can't see a thing

 

UPDATED MY CLIMATE DISEASE PREDICTIVE MODEL APP (from livingturf.com.au) SHOWING EXTREME DISEASE ALERT FOR PYTHIUM IN SYDNEY

Photo 5-12-2014 11 05 51 Photo 5-12-2014 11 05 54

As you can see tfrom Monday 1st pythium pressure increased dramatically and is still extreme to high. Recommendation is Proplant as Proplant works in all disease pressure conditions especially known and proven as a strong pythium fungicide

Overnight I was speaking to a few supers on twitter on how much rain they received. There was quite  a difference with western Sydney copping about 45mm of rain while the eastern suburbs only got around 8-18mm which is very surprising since they are the ones who always get a drenching.

What all this means is that disease pressure is very high to extreme (my climate app report) at the moment and will be staying high for the next few days at least. Having a preventative program is the best option however even the best prevention program needs a little fine tuning. Here at Campbell’s we have Proplant available for pythium and is on the of the best products on the market available due to its curative abilities and longest residual over nay other pythium product. Proplant has been a trusted fungicide by meany turf managers for over 10 years now. In our trial work we did with Proplant we compared it against a standard pythium fungicide and found that the standard gave only 7 days residual while Proplant even at both the low and high rates gave 28 days.

For more information see the brochure here Proplant Brochure

Also have a look at our guide to managing pythium not just from a chemical point of view but from a cultural view. Disease guide rhizo eri pythium 2014

Managing pythium is not just use fungicide but use every tool you have at your disposal and make observations on your turf. You need to take a holistic approach from mowing practices, watering practices and inputs you are using. See our guide to find out more.

Pythium December 2012

 

 Pythium can be very destructive as seen on these bent grass golf greens

 

This is ashort post that you may hva eseen published on www.turfmate.com.au wesite as well.

 

Pythium is one of the most destrcuctive diseases of turf.  There are mnay species of pythium but the ones commonly found in Australia are pythium blight and

 

All turf species are affected but predominately fine cut turf of bent and couch grass. Pythium appears as circular spots during warm to hot humid weather. Spots appear as brown to bronze in colour. Pythium causes a wide range of damage including root and leaf blight. Outbreaks are most severe following warm nights coupled with humid days. Pythium is also very active during the seeding process as frequent watering is taking place, creating a humid and wet environment. Pythium can spread a number of ways including:

  • mowers
  • traffic
  • water- especially if water is from a dam or effluent as spores can be present.
  • poor drainage
  • low soil pH is ideal environment for Pythium along with high pH can lead to other disease issues
  • high soil nitrogen levels.


Pythium is always living in the soil and needs the right conditions to cause problems. Water logged greens are a perfect environment for Pythium. You can see Pythium as patterns in greens that follow the drainage lines. Equipment use also spreads the disease.

If you have a short root system with compacted soil and poor drainage, your turf will need extra light watering to keep it alive. This will increase Pythium pressure, due to plant wetness. On the other hand, deep infrequent watering can increase Pythium pressure as well as the roots and the soil are being completely soaked which is conducive to Pythium outbreaks. Very hard to win in this situation. That is why it is important to maintain healthy turf and to use specific Pythium fungicides on a preventative basis.

If you do have an outbreak with any disease, not just Pythium reduce the use of PGR’s until you get recovery. Also look at at tank mixing your fungicide as other diseases maybe present. An Ippon & Proplant tank mix is very effective here.

A hot summer can lead to an increase in Pythium as well – from over watering and a constant need to water

Cultural Controls of Pythium:

  • Avoid too much N
  • Keep plants healthy as possible with using root stimulants.
  • Avoid mowing in moist hot weather
  • Raise mowing heights
  • Avoid verti cutting, top dressing if greens are infected  as it puts more stress on the plant
  • Reduce leaf wetness
  • Increase air flow and sunlight to Pythium prone areas

  

Our Chemical control Solution

  • Proplant 45mL-65mL per 100m2 – apply with suficient water for good coverage. Water in 2-5mm. Proplant is a systemic fungicide that mnoves in an upwards direction and has both prevtantive and curative properties.
