    1. Current status and strategies to avert the risks and losses associated with pests, diseases and natural disasters in cocoa for the Caribbean Leon Granger CARIBBEAN FINE COCOA CONFERENCE & CHOCOLATE EXPO Jamaica Sep. 2011

    2. Focus Update from last Presentation on these Issues Brief Historical Perspective: Problems & Solutions Whats Happening Today: Current Status & Strategies to Avert Risks & Loses from Pests, Diseases, and Natural Disasters 2

    3. Update from Previous Presentation - Threats Several Threats to Fine Cocoa were reviewed in a Paper presented at the CFCF Conference at the Hyatt Regency Hotel, Trinidad, in 2010 Diseases are of Primary Concern Caribbean & Globally Main limiting factor and most important threat for cocoa worldwide (Phillips-Mora, 2008, WCF) 3

    4. Brief Historical Perspective: Problems & Solutions Production losses due to: Diseases Three major cocoa diseases affecting the tropics and the Americas: Witches broom, Black pod, and Frosty pod rot Frosty pod rot is not present in the Caribbean Islands Pests Natural Disasters 4

    5. 5 There are three major cocoa diseases affecting the tropics and the Americas: Witches broom, Black pod, and Frosty pod rotThere are three major cocoa diseases affecting the tropics and the Americas: Witches broom, Black pod, and Frosty pod rot

    6. 6 This map shows the regional distribution of major cocoa diseases This map shows the regional distribution of major cocoa diseases

    7. 7 This map shows a region of Latin America where 11 countries are affected from Peru to MexicoThis map shows a region of Latin America where 11 countries are affected from Peru to Mexico

    8. 8 And this next map shows frosty pod migration from the 1950s to Present Frosty Pod Rot Disease is not new, and actually has been reported since 1851 Spreading generally north and south from a centre of activity. Important questions are: Would it get to the Caribbean? What can we do to protect our precious fine/flavour crop? Can we keep it out? How long can we keep it out?

    9. Highlights from the Map All pathogens have limited geographic distributions, mostly limited to a specific region This implies that we can contain these diseases and manage them for best productivity 9 Some important highlights from the map are: (1) All pathogens have limited geographic distributions, mostly limited to one continent, (2) This implies that we can contain these diseases and manage them for best productivitySome important highlights from the map are: (1) All pathogens have limited geographic distributions, mostly limited to one continent, (2) This implies that we can contain these diseases and manage them for best productivity

    10. GLOBAL THINKING Rehabilitation efforts Biodiversity enhancement Potential for sustainability 10 These problems affect the Caribbean and Global Cocoa farms, and as such we could learn a lot from international efforts Some of the effective strategies used in Global Thinking are Rehabilitation efforts Biodiversity enhancement Potential for sustainability These problems affect the Caribbean and Global Cocoa farms, and as such we could learn a lot from international efforts Some of the effective strategies used in Global Thinking are Rehabilitation efforts Biodiversity enhancement Potential for sustainability

    11. Whats Happening Today: Current Status & Strategies to Avert Risks & Loses in the Caribbean from Pests, Diseases, and Natural Disasters 11

    12. Focus in the Caribbean Historical Efforts are being Updated New Threats are kept at bay Reducing Vulnerability to Threats Prevention Efforts Mobilizing Crop Protection Specialists 12

    13. Updated Historical Protection Strategy Cultural practice Shade reduction Regular harvesting Frequent weed control Other agronomic practices Choice of latest resistant varieties 13 Change picture?Change picture?

    14. Key Problems: Threats to Cocoa Production Fungi Insects Birds: Parrots and Woodpeckers Rodents: Rats and Squirrels Natural disasters: Hurricanes and Droughts 14 Lets take a closer look at threats specifically fungi, insects, birds, rodents, and natural disastersLets take a closer look at threats specifically fungi, insects, birds, rodents, and natural disasters

    15. Disease Triangle In examining diseases Crop protection specialists view components of a disease as a triangle consisting of: Host Pathogen, and Environment 15 As a result of these diseases as threats, Crop Protection Specialists, view components of disease as a disease triangle consisting of: Host, Pathogen and EnvironmentAs a result of these diseases as threats, Crop Protection Specialists, view components of disease as a disease triangle consisting of: Host, Pathogen and Environment

    16. New Threats Kept at Bay: Controlling Diseases The Modification, Removal, Reduction, or Elimination of any component of the triangle (Host, Pathogen or Environment) as a management strategy, would result in control of the disease 16

    17. Solutions for Witches Broom Resistant varieties have been the answer for Trinidad and Tobago Jamaica and the Islands north of Grenada are free of the disease and must continue their excellent vigilance All aspects of this complex disease are poorly understood and no firm recommendations on control can be proposed 17 Regarding Solutions for Witches broom Resistant varieties have been the answer for Trinidad and Tobago; Jamaica and the Islands north of Grenada are free of the disease and must continue to be vigilant; All aspects of this complex disease are poorly understood and no firm recommendations on control can be proposed Regarding Solutions for Witches broom Resistant varieties have been the answer for Trinidad and Tobago; Jamaica and the Islands north of Grenada are free of the disease and must continue to be vigilant; All aspects of this complex disease are poorly understood and no firm recommendations on control can be proposed

    18. Averting Risks: Black Pod Disease Shade reduction Drainage of excess field water Pruning Underbrushing and field sanitation Use of resistant varieties Chemical application of copper fungicides 18 The solutions to black pod disease include: Shade reduction; Drainage of excess field water; Pruning; Underbrushing and field sanitation; Use of resistant varieties; Chemical application eg copper fungicides The solutions to black pod disease include: Shade reduction; Drainage of excess field water; Pruning; Underbrushing and field sanitation; Use of resistant varieties; Chemical application eg copper fungicides

    19. Parrot Damage Parrots are predominant in Tobago Falconers use their hawks, falcons and eagles to control parrots in bearing fields Pods are being bagged or sleeved for protection against birds and rodents at Doves estate in Tobago 19

    20. Other Caribbean Strategies Field sanitation Trapping of squirrels and rats in Jamaica Legal removal of hatchlings in Tobago and sold to pet trade for additional income Planting of fruit trees in the State forests to attract vertebrate pests 20

    21. Cocoa and Natural Disasters Jamaica is affected by annual hurricanes Ivan and Emily wrecked havoc on Grenadas farms which are still reviving Tobago has been affected by Hurricane Flora but 45 years later there is still a rebirth in motion 21 A final threat to fine cocoa is natural disasters, specifically hurricanes. Jamaica has been affected by annual hurricanes; Ivan and Emily wrecked havoc on Grenadas farms which are still reviving; Tobago has been affected by Hurricane Flora but 45 years later there is still a rebirth in motion A final threat to fine cocoa is natural disasters, specifically hurricanes. Jamaica has been affected by annual hurricanes; Ivan and Emily wrecked havoc on Grenadas farms which are still reviving; Tobago has been affected by Hurricane Flora but 45 years later there is still a rebirth in motion

    22. Coping with Hurricanes Plant seedlings or grafted plants Avoid vegetative clones Plant windbreaks Keep cocoa trees pruned and under 12 feet Do sanitary and reconstructive pruning after hurricane damage Natural pruning from hurricanes is followed by an increase in production 22 Some effective strategies for Coping with Hurricanes include: Plant seedlings or grafted plants; Avoid vegetative clones; Plant windbreaks; Keep cocoa trees pruned and under 12 feet; Do sanitary and reconstructive pruning after hurricane damageSome effective strategies for Coping with Hurricanes include: Plant seedlings or grafted plants; Avoid vegetative clones; Plant windbreaks; Keep cocoa trees pruned and under 12 feet; Do sanitary and reconstructive pruning after hurricane damage

    23. Controlling Threats: Outcomes Important to control threats because it leads to improved outcomes High crop yields can be achieved, with sustainable agriculture, if plants are protected from pests, diseases, and natural disasters 23

    24. Reducing Vulnerability to Threats: Multidimensional Approach Farmer Education New disease resistant varieties Implementation of Best Practices Systematic Field Surveys Early Detection or Prevention 24

    25. Efforts Within the Last Year 25 Surveys New Resistant Varieties Focus on the Farmer Understanding the role of the farmer in protection efforts Partnering with Farmers to improve outcomes

    26. Crop Protection Measures for Farmers Farmers need crop protection measures: That are affordable so that farmers can take advantage of them Simple Easily applicable Cost effective enable farmers to make profits and prosper Sustainable so that production is also sustained 26 Change picture?

    35. Mobilizing Cocoa Specialists Crop protection specialists and Cocoa Extension Officers are critical for increasing awareness, developing partnerships, and identification and evaluation of diseases and continued production of Fine/flavour cocoa. 35 As a result of these diseases as threats, Crop Protection Specialists, view components of disease as a disease triangle consisting of: Host, Pathogen and EnvironmentAs a result of these diseases as threats, Crop Protection Specialists, view components of disease as a disease triangle consisting of: Host, Pathogen and Environment

    36. Improving Outcomes 36 In order to improve outcomes against threats we must have strong partnerships between Government Officers, Researchers, Farmers, Purchasers and a good overall knowledge base of threats and solutionsIn order to improve outcomes against threats we must have strong partnerships between Government Officers, Researchers, Farmers, Purchasers and a good overall knowledge base of threats and solutions

    37. Continued Need for Research Early Assessment of Disease threats Think-Tanks on Viable Prevention Efforts Better Understanding of Routes of Transmission 37 All of this information points to the fact that there is tremendous continued need for research so that there can be early assessment of disease, think-tank workgroups can examine viable prevention efforts, and there can be increased understanding of routes of transmission of diseases and threats to our fine cocoa industryAll of this information points to the fact that there is tremendous continued need for research so that there can be early assessment of disease, think-tank workgroups can examine viable prevention efforts, and there can be increased understanding of routes of transmission of diseases and threats to our fine cocoa industry

    38. Crop Protection Measures Outcomes Implementation of crop protection measures important ~ produces desirable results: Plants which grow vigorously Absorb nutrients more efficiently Compete with weeds, and Yield according to environmental constraints 38 Change picture? Change picture?

    39. Reducing Vulnerability to Threats: Pests, Diseases & Natural Disasters The Caribbean must mount a campaign to protect its precious crop Losses of 70% -80% reported A viable combination of regional efforts started through the CFCF must be sustained Collaboration is imperative Develop new partnerships for the Caribbean No island can stand alone 39 Given the widespread movement of FPD - Its important to have effective Early Detection and/or Prevention strategies. Phytosanitary measures are labour intensive; In Trinidad and Tobago this is expensive; The Caribbean must mount a campaign to protect its virtuous and precious crop; A viable combination must be derived; in order for this to happen we must strongly encourage Regional Efforts; Collaboration is imperative; since No island can stand alone Given the widespread movement of FPD - Its important to have effective Early Detection and/or Prevention strategies.
