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)

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

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

14 Let’s take a closer look at threats – specifically fungi, insects, birds, rodents, and natural disastersLet’s 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

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

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

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

21. Cocoa and Natural Disasters Jamaica is affected by annual hurricanes
Ivan and Emily wrecked havoc on Grenada’s 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 Grenada’s 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

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

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 - It’s 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
