Instructions for use
  • Shake or stir well before use.
  • Store in a cool dry place away from direct sunlight. This product has been tested and can be stored safely at temperatures from 5°C to 25°C.
  • The product may crystallise at too cold temperatures (<5 °C).
  • For the best results, apply Optima Leaf-Trace in the 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. Product is stable at a pH of 3.0 - 12.0. In combination with products containing phosphate, always test for combinability first.
  • Never mix pure products together. We recommend carrying out a trial application on a small area first, before applying to the entire plot.
  • The best before date on the upper side is guaranteed if the product is stored according to these guidelines in the unopened original packaging. Only store in the original packaging and close the cap immediately after use.
