Directions for Use

Sportsmaster WSF products are tank-mixable with other products within the range and H2Pro & H2Pro Maximise wetting agents.

To ensure that this product dissolves completely: all products should be mixed by adding the quantity required to a ½ full spray tank, then agitating for 10 – 15 minutes. Then fill the tank to full capacity with water. The water temperature will affect the dissolution rate.

Avoid applications during frosty or drought conditions. The water volume used to apply Sportsmaster WSF will affect how nutrients are taken up by the plant.

Mix with TurfMark® Extra spray pattern indicator to aid spraying, condition water and minimize spray drift.

For foliar applications use low water volumes (300 – 600 L/Ha) and to optimize uptake avoid high temperatures and sunny conditions.

For root uptake applications use high water volumes (600 – 1000 L/Ha) and follow immediately with a minimum of 2 – 3 minutes irrigation to provide the necessary water volume and to reduce the risk of turf injury.
