Key Benefits

  • significantly higher boron efficiency due to the penetrant effect of nitrogen and phosphorus
  • highly efficient and easy to handle
  • further improved buffering of the spray solution into the slightly acidic range (pH 6.5)
  • improves resistance to drought stress of young agricultural crop plants (e. g. 6 - 10 leaf stage)
  • guarantees phosphate supply via the leaf under unfavorable conditions such as cold spring, drought periods etc.
  • well compatible with many pesticides
  • applicable in hard water up to 40° dH (degree of water hardness)
  • increased boron and phosphorus content
  • may partly substitute oil
