TRIAL DATA FOR ADJUVANTS IN HARD WATER

Outright 770 SPRAY ADJUVANT Glasshouse Trial:

Glasshouse Trial

Glyphosate applied at 222g a.i./ha with 11001 nozzle @ 64L/ha to Oats at 1.5-2 leaf. Assessment by fresh weight 14 DAT. The trial shows that increased water hardness results in reduced efficacy when Glyphosate is applied without suitable adjuvants. In this trial OUTRIGHT 770 Spray Adjuvant when applied at either 0.25% or 0.5% effectively softens the water and provides the efficacy enhancement from its surfactants and oils.
