Dacogreen WeatherShield “The Ultimate Chlorothalonil”
Some facts you may not be aware of in regards to chlorhthalonil in Australia:
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.
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
An update from the Ultimate Chlorothalonil
Did you know we have also put Dacogreen through some rigorous formulation testing? It was quite amazing what we found with products we tested that claimed high quality but after testing showed them to be well below. So next time someone says they are the same or have stickers in their formulation get them to prove it. We know we can.
