Cacao swollen-shoot virus ambitious and costly eradication effort of any country in the world against a viral plant disease. Cacao swollen-shoot virus (CSSV) principally infects "Theobroma cacao" (cacao tree) and has a major effect on crop yields. Within one year of infection yields decrease by 25%, and within two years by 50%. The trees are usually killed within 3 to 4 years. Symptoms vary depending on the strain of virus. Main symptoms include: leaf chlorosis (interveinal), root necrosis, red vein banding in young leaves, small mottled pods, and stem/root swelling followed by die-back. CSSV has also been isolated from alternative hosts "Cola chlamydanta",
