  • Poor seed vigor 
  • Reduced size of leaves,  misshapen leaves

  • Chlorotic leaves and dieback  in citrus 
  • Rosetting and/or “little leaf”  in fruit trees
  • “Tram lining” in corn (light  striping on both side of midrib) 
  • Bronze spotting on older leaves later giving a mottled appearance in legumes
  • Reduced development and  size of fruit 


  • Formation of chlorophyll

Treatment Options

Apply Zinc onto crops grown on high pH or heavily limed or manured soils; crops grown on peat or muck soils with high organic matter; crops grown on light, sandy soils or soils with low organic matter. Soils with high content of N, K or Mg can reduce the availability of Zn. Also, when conditions are cold and wet in the spring Zn availability become low
