Mango Glossary

Dieback is progressive death of shoots or branches, often beginning near their tips and extending backward. On mango it can be associated with pathogens, injuries, root problems, or environmental stress, so it describes a pattern rather than one confirmed disease. Look for the boundary between living and dead wood, recent damage, and other symptoms before deciding how much to remove. Use suitable sanitation and timing when pruning, and investigate the underlying cause instead of assuming fertilizer or a generic spray will restore dead tissue.

Gummosis is the exudation of gum-like material from damaged or stressed plant tissue, often visible on mango trunks or branches. It is a symptom rather than a single disease: injury, insects, infection, and environmental stress can produce similar appearances. Examine the site for wounds, boring holes, discoloration, and spreading dieback before deciding on management. Repeatedly cutting or coating the area without identifying the cause can worsen damage. A diagnostic assessment is more useful than assuming every gum deposit has the same treatment.
