Concert Spray Adjuvant is for use with Glyphosate-based herbicides to minimise antagonism when mixing with flowable herbicides and improve performance under adverse environmental conditions. When used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides, Concert Spray Adjuvant functions to bind iron and calcium cations that are present in both hard water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), Glyphosate, and Glufosinate herbicides.
Concert Spray Adjuvant contains ammonium sulphate that minimises the impact of hard water on glyphosate and reduces antagonism between glyphosate and other herbicides. Concert should be used with non-selective herbicides only, as with some selective herbicides use may result in loss of selectivity and therefore crop damage. Ammonium Sulfate may be corrosive to metal parts of the sprayer. Thoroughly flush tanks, pumps and nozzles with water after use.
What is the mixing rate for Concert Spray Adjuvant (Ammonium Sulfate);
When being used to minimise antagonism to tank mixes with flowable herbicides & improve pesticide performance under adverse environmental conditions mix at a rate of 2-Litres per 100-Litres of spray solution.
Do I really need to add Concert Spray Adjuvant Ammonium Sulfate to my Glyphosate spray mix?
The answer is yes, particularly if the water you are using is ‘hard’ (ie bore water/groundwater). It is surprising how many producers don’t bother to add ammonium sulfate. Hard water in glyphosate spray mix results in “hard water antagonism,” which ties up the glyphosate and does not allow it to be absorbed as easily into plants. The magnesium and calcium contained in hard water combine with glyphosate to form glyphosate-magnesium and glyphosate-calcium compounds which result in poor uptake and poor weed control. Simply adding surfactants to glyphosate products improves the spreading of the spray over the plant and results in greater absorption, but does not address the hard water problem.
Including ammonium sulfate may add a little work and expense, but getting the best performance from your glyphosate application is worth it.
