  • Delayed or stunted growth:Plants grow more slowly and new shoots remain shorter and weaker.
  • Weak leaves:The leaves become thin and brittle.
  • Reduced flower formation:Iron deficiency can inhibit flower development, which affects fruit and seed production.

The product is applied as a foliar spray.

Precautions and Liability

Temperatures below +5 °C and above +40 °C, as well as frequent temperature fluctuations during transport and storage, should be avoided. Excessively low temperatures can lead to crystallization. These crystals are completely water-soluble and dissolve again in the spray solution. Prolonged storage may cause color changes. Neither crystallization nor color changes affect the desired physiological product quality in any way. When mixing with other products for the first time, a small-scale test should be carried out before general use. As the storage and use of fertilizers are beyond our control, we can only guarantee the satisfactory quality of the product at the time of delivery.
