Optik Blue Plus is an enhanced spray pattern dye designed to highlight and help eliminate overlapping sprays, missed areas, spray drift or blocked nozzles. It may also be used for marking out temporary greens. Optik spray pattern dyes will remain visible for 24 - 48 hours, after which they will gradually fade depending on light intensity and/or rainfall.
Optik Blue Plus reduces the pH of spraying water, protecting pesticides from losing activity. The added surfactants to help spread the droplets on the leaf surface and the complexing agents reduce the staining effect of the dye. The anti-drift component reduces chemical trespass. Optik Blue Plus should be used at 250ml per 100 lt water. Adding 250ml of Optik Blue Plus to 100 litres of spraying water with a starting pH of 7.6 will reduce it to approx. pH 4.5.
