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.

Extreme Disease pressure January 2016 -NSW

What a start to the year for NSW. After a a great greenkeepers Christmas January has turned to the extreme with high temps humidity and rainfall.

I started to see a few sick turf surfaces around the place just due to sheer pressure.

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 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 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
  • 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

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 the live blog I’ll be doing with Turf Republic again and along with my twitter feed. I will post all the link the week before.

Summer is upon us – November 2014

Well as alot of you do as I do we constantly look at the weather to see what possible turf growing conditions we are facing. At the moment we are looking for some rain (well majority of us are but  the golf tournaments are starting and the less variables the better).

I did a post on preparing for the heat last season and i thought it may be a good one to revisit just as a refresher with a few updates. If you at the past post the weather maps are quite similar for the long term forecast. (see 2013 post here).

 

  • Start with a strong foundation early.Don’t skimp.
  • Review what you did last year and change what did not work.
  • Increase root health -Use root stimulants such as kelp, amino, humic fulvic acid products
  • Look at your irrigation practices- This will be harder as the summer goes on especially when your cool season grasses are stressing out with a shorter root system. Keep the soil moisture consistent as not to stress our turf. There is no right or wrong method here but the aim is to get desired turf conditions (as Dr. Micah Woods says). (This is where soil mositure metres come in very handy- more on that in a future post). For an expalnation on water irrigation management have a look at the picture below from Micah Woods at the Asian Turfgrass Centre For more information on this work below see this link to his blog post.

 

 

 

 

  • With warm season grasses protect your turf early on as the root system is still not fully active.
  • Do a preventative fungicide and insecticide program. (if anyone would like a program designed for them please contact me). Under stress conditions some systemic fungicides may take longer to be taken up as the plant will not be fully functioning properly so be wary of this and apply fungicides on a prevention basis.
  • Have a wetting agent program and start earlier rather than later
  • When hand watering use wetting agent tablets to help cure and prevent localised dry spots
  • Increase your height of cut. This will go a long way to help manager all types of stress with minimum disruption to greens speeds.
  • Communicate with your stakeholders the stresses the turf is going under to give them an understanding of the situation and to better support you in the long run.

 

I have a few product profiles coming as well but in the meantime I have been getting asked why Dacogreen WeatherShield is different to other chlorothalonil products. It lies in the active ingredient and the formulation. Dacogreen remember used be Daconil until about 10 years ago, we just had a name change.

See my post from last year here
