Ellison Es'harpton

Caribbean botanist who prevented the 1930s coffee blight

This forgotten scientist from Dominica developed the world's first biological pesticide using:

• Antagonistic fungi cultures from volcanic soil
• Microencapsulation technique with plant resins
• Wind dispersal system adapted from seed pods

His 1932 field trials showed 89% effectiveness against coffee rust fungus. Despite initial success, colonial authorities suppressed the technology to protect European chemical interests.

Modern research confirms Es'harpton's methods could:

• Reduce pesticide use by 40%
• Enhance soil biodiversity
• Provide climate resilience
