Transcript of "Significance of seed borne diseases on crop production in bangladesh"

  1. 1. SIGNIFICANCE OF SEED BORNE DISEASES ON CROP PRODUCTION IN BANGLADESH
  2. 2. OBJECTIVES To know about the seed borne pathogen and seed borne diseases of important economic crops. To concern about the annual loss of crop production by seed borne diseases. To know about seed infection, their establishments and seed borne plant infection. To ensure about the seed health standard and field health standard of notified seeds. To know about the management or control of the seed borne diseases.
  3. 3. SEED: Any plant part such as root ,stem, leaf,bulb,rhizome etc.containing viable embryos used as propagative unit or the fertilized matured ovule constituting the genetic potentiality capable of germination to produce new plants for desired harvest is called seed.
  4. 4. SEED BORNE DISEASE  Any malfunctioning of host or plants those results from continuous irritation by a pathogenic agent which are carried by seed and transferred to the plants and leads to development of symptoms are called seed borne diseases.
  5. 5. LIST OF SEED BORNE DISEASES DISEASES PATHOGEN Black point of wheat Bipolaris sorokiniana Brown spot of rice Bipolaris oryzae Alternaria blight of mustard Alternaria brassicae Leaf spot of wheat Alternaria tritica Purple stain of soybean Cercospora kikuchi Red rot of Sugarcane Colletotrichum falcatum Black band of Jute Botryodiplodia theobromae Anthracnose of jute Colletotrichum corchori Stem rot of jute Macrophomina phaseolina
  6. 6. Seed Borne diseases of Rice Brown Spot of Rice Grain Spot of Rice
  7. 7. Seed Borne diseases of Wheat Black Point of Wheat
  8. 8. Seed Borne diseases of Jute Anthracnose Stem end rot
  9. 9. Seed Borne diseases of Sugarcane Red rot of Sugarcane
  10. 10. Seed Borne diseases of Lentil Foot & Root Rot of Lentil
  11. 11. Diseased pulse Seed
  12. 12. Seed Borne diseases of Soybean Purple stain of Soybean
  13. 13. Seed Borne diseases of Chilli Anthracnose of Chilli
  14. 14. Seed Borne diseases of Bean Anthracnose of Bean
  15. 15. ROLE OF UNHEALTHY SEED  Germination failure  seedling diseases  Adult plant infection  Inoculation of virgin soil  Introduction of new area  Foci of primary infection  Secure virulent physiologic races  Seed discoloration  Viability loss  Lower market value
  16. 16. LOSSES DUE TO SEED BORNE DISEASE RICE Germination failure Pathogen % loss Curvularia lunata 37% Fusarium sp. 13% Field loss Curvularia sp. 59.5% Storage Bipolaris oryzae 20-63%
  17. 17. Wheat Pathogen Loss % germination Bipolaris sorokiniana 3.40% Fusarium sp. 17-19.7% Onion % germination Alternaria porri 51% Jute % germination Macrophomina phaseolina Combined Botryodiplodia theobromae 39.4% Colletotrichum corchori Yield loss Wheat Bipolaris sorokiniana 14.97% Sesame Macrophomina phaseolina 5-10% Country bean Colletotrichum lindemuthinum 5%
