Complete answer:
Little leaf disease of Brinjal is caused by a Mycoplasma-like organism called Phytoplasma. The name MLO (Mycoplasma-like organisms) was one of the early names provided during the classification. This disease is a vector transmitted disease, where Hishimonus phycitis is the vector.-Hishimonus phycitis (the cotton leafhopper) is a pest insect with green and white distant epidermal colors, and are seen abundantly in tropical and subtropical regions.
-The major symptoms of Little leaf are chlorosis of new leaves intervening, deformation, and negligence of leaves through the midrib to grow and common shortening of plants.
-Eggplant is the common name of brinjal, which is a species of plants that belong to the family Solanaceae. The fruit of Solanum melongena is edible and is cultivated worldwide and commonly looks purple and the soft fruit is a major part of several dishes.

Note: -Some secondary symptoms of little leaf disease contain halting of terminal development, new leaves with deformed and weak midribs, and axillary buds with very small, deformed growth.
-The increased temperature of the soil, the moisture of soil, and the presence of accumulation of bacterial/fungal population in the soil are factors that increase the chance of infections.
-Removing weeds of solanaceous that occupies the vector and spraying insecticides to the infected plant can help minimize pest populations to control the spread of this disease.
