Instructions for use
  • Shake or stir well before use.
  • Store frost free, indoors in a dark place.
  • The product may crystallise at too cold temperatures (<5 °C).
  • For the best results, apply Optima Leaf-Trace in the early morning or late afternoon, to avoid strong sunlight. This minimises the risk of crop damage due to leaf burn. If the crop stays wet for longer, the nutrient uptake is improved.
  • Optima Leaf-Trace is generally compatible with other products. However, with a pH more acidic than 4, Optima Leaf-Trace can react with phosphate fertilisers.
  • Never mix pure products together. We recommend carrying out a trial application on a small area first, before applying to the entire plot.
  • This product has a shelf life of 3 years from the moment of production. The shelf life of the product is stated on the label. Opening the packaging in the meantime has no influence on this. As long as the guidelines for storage are followed the expiry date (BB) on the label is leading.
