Glossary

A physiological disorder is an abnormal plant or fruit condition arising from developmental or environmental processes rather than an infectious pathogen. Mango internal breakdown, chilling injury, and some nutrient-related problems fall within this broad category. The distinction matters because a fungicide cannot correct every blemish or internal defect. Different causes can produce overlapping appearances, and damaged tissue may later decay. Examine timing, handling history, and representative fruit before assigning a cause or recommending a treatment.
