Application benefits

  • Regulates transpiration and prevents water loss from plants
  • Increases plant resistance to drought, low temperatures and pathogens
  • Optimises the use of nitrogen
  • Stiffens stems and reduces susceptibility to lodging
  • Stimulates photosynthesis and assimilate transport
  • Improves yield quality by increasing starch, organic acids, protein, fat, sucrose, carotene, vitamins B1 and C
