This book reviews the current state of knowledge concerning cacao pathogens and methods for
their management. Topics discussed include the history biology and genetic diversity of
Moniliophthora species (which cause witches' broom and frosty pod rot) and Phytophthora species
(which cause black pod rot) that cause diseases resulting in major losses to cacao production.
Emerging pathogens such as Cacao swollen shoot virus and Ceratobasidium theobromae (which
causes vascular streak dieback) are also discussed in detail along with many pathogens of
significant local concern. Most of these pathogens represent major risks to global cacao
production should they expand into new areas breaking out of their current limited
distributions. By considering cacao diseases as a group similarities in the available tools
and techniques used in their management become apparent as do their limitations. Gaps in our
current knowledge of cacao pathogens and the management of the diseases they cause are detailed
and suggestions for future research directions are provided. This insight allows readers to
consider cacao disease threats from a more comprehensive global perspective and paves the way
for an improved synergy of efforts between the various research programs agencies and
industries both private and public with vested interests in cacao production and cacao
farmers.
