What is the coal disease of coconut? How is the ecology of the disease? Do you want to know.

Symptoms: black soot-like hyphae are produced on the lower or upper surface of the leaves, and in serious cases, a whole piece of black cover covers the leaves, seriously affecting the normal physiological function of the leaves.

Disease ecology: coconut leaves produce honeydew secretions on the leaves due to the harm of aphids and shell insects. Coal bacteria use secretions as nutrients from leaf surface reproduction. The disease is especially poor ventilation and occurs more seriously when the sunshine is insufficient.
