The Role of Micronutrients in Crop Health and Disease Resistance

Published on

Micronutrients are critical components of plant development. Seven of the most important elements to consider are boron, cobalt, copper, iron, manganese, molybdenum, and zinc. Each of these nutrients is important for disease resistance and high-yield production.

In this webinar, John provides an in-depth look at these seven micronutrients. For each one, John discusses their functions within the plant, as well as the disease and insect prevention benefits each can provide with the correct management. John also talks about micronutrient mobility within the plant and the different methods of chelation. Watch this webinar to learn:
• Important aspects in the management of each micronutrient
• Application of xylem-mobile versus phloem-mobile nutrients

• The difference between synthetic and organic acid chelation

The Role of Micronutrients in Crop Health and Disease Resistance

  1. 1. THE ROLE OF MICRONUTRIENTS IN CROP HEALTH AND DISEASE RESISTANCE A Webinar Hosted by AEA, Featuring John Kempf
  2. 2. We believe micronutrients are critical to develop insect and disease resistance.
  3. 3. ● Boron ● Cobalt ● Copper ● Iron ● Manganese ● Molybdenum ● Zinc Let’s look at 7 primary micronutrients:
  4. 4. Boron increases/guides sugar translocation to the sugar sinks. Boron increases calcium absorption and mobility. Boron
  5. 5. ● Rhizoctonia ● Verticillium ● Fusarium ● Some viruses Adequate Boron increases plant resistance to: References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  6. 6. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  7. 7. AN Cobalt inhibits the formation of ethylene and delays senescence. Cobalt
  8. 8. Copper increases stalk and stem flexibility and strength Copper
  9. 9. ● various Pseudomonas ● Erwinia (fireblight) ● Bacterial canker ● Bacterial speck ● Bacterial spot ● Bacterial wilt ● Apple scab ● Anthracnose Adequate Copper increases plant resistance to: ● Damping off ● Root rot ● Cotton wilt ● Downy mildew ● Powdery mildew ● White rot ● Early blight ● Late blight ● Mosaic virus References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  10. 10. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  11. 11. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  12. 12. Iron Iron is required for chlorophyll concentrations. Iron can greatly increase photosynthetic efficiency.
  13. 13. Manganese is essential for water hydrolysis, the first step in photosynthesis. Manganese is essential to regulate potassium absorption and movement. Manganese needs to be absorbed in the reduced form. Manganese
  14. 14. • Phytophthora • Anthracnose • Rhizoctonia • Fusarium • Late blight • Potato scab • Downy mildew Adequate Manganese increases plant resistance to: • Powdery mildew • Mosaic viruses • Bacterial speck • Early blight • Verticillium • Bacterial canker References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  15. 15. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  16. 16. Molybdenum is needed for nitrate reductase enzyme to convert nitrates to amino acids. Molybdenum is needed for nitrogenase enzyme complex found in symbiotic nitrogen fixing organisms. Molybdenum
  17. 17. ● verticillium ● angular leaf spot ● powdery mildew ● xanthomonas ● all viruses ● inhibits nematodes Adequate Molybdenum increases plant resistance to: References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  18. 18. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  19. 19. Zinc determines leaf size and uniform shape. Zinc
  20. 20. ● rhizoctonia ● fusarium ● phytophthora ● potato scab ● mosaic virus ● reduces aflatoxins Adequate Zinc increases plant resistance to: References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
  21. 21. References from Mineral Nutrition and Plant DIsease by Dr. Don Huber
