A natural alternative treatment for citrus greening, using curry leaf tree extract injected directly into tree trunks. Citrus greening has no cure and has reshaped citrus agriculture wherever it has spread.
Choosing a disease with no existing cure sets a low bar for improvement and a high ceiling for impact. The delivery route — trunk injection rather than spraying — is a separate decision that had to be justified on its own.
- Botanical extract preparation
- Trunk injection delivery
- Citrus greening disease assessment
- Treated versus untreated tree comparison
- An unsolved problem in your own region is usually the best available project
- Treatment and delivery method are two choices; be ready to defend both separately
