Copper

• Marginal chlorosis of young leaves
• Twig dieback 
• Pigtailing 
• Necrotic, brown spots over leaf surface
• Reduced growth and yields.

• Chlorophyll production 
• Photosynthesis 
• Production of proteins 
• Involved in several enzyme systems
• Oxidation reduction reactions 
• Formation of lignin 
• Water movement regulation
• Seed production

Apply Copper onto crops subject to excess Nitrogen or Phosphorus; crops grown on high pH or heavily limed soils; crops grown on peat or muck  soils with high organic matter; crops grown on leached out acid soils  or sand; or when the conditions are cold and wet in the spring, delaying the availability of Cu. Soils high in Manganese content can reduce the availability of Cu.
