Little leaf of brinjal is caused by:

✅Explanation:
Little leaf of brinjal is a plant disease caused by a phytoplasma, a type of bacteria-like organism that lacks a cell wall. It is transmitted by leafhoppers, specifically the species Hishimonus phycitis. The disease causes stunted growth, reduced leaf size, and yellowing of leaves in brinjal (eggplant) plants. Phytoplasmas are specialized pathogens that infect plant phloem tissues and are known to cause various plant diseases.

🛑 Additional Information::
Little leaf of brinjal – 
Little leaf of brinjal is caused by a plant pathogenic mollicule, Phytoplasma (earlier known as mycoplasma-like organism or MLO).
Phytoplasmas are phloem-limited pleomorphic bacteria lacking the cell wall.
Disease: Little leaf of brinjal
A serious viral disease of brinjal.
Transmitted by leaf hoppers (Cestius (Hishimonus) phycitis and Amrasca biguttula biguttula).

• Symptoms:
Infected plants show light yellow leaves in the early stages.
Leaves reduce in size and become malformed.
Plants appear shorter in stature, with a bushy appearance due to a large number of branches, roots, and leaves.
Petiole shortening.
Many buds appear in the axil of leaves.
Shortened internodes.
Deformed flower parts, leading to plant sterility.
Infected plants do not bear fruit or the fruits that form are hard, tough, and fail to mature.

• Control Measures:
Sanitary measures: Eradicate susceptible volunteer crops from previous plantings to reduce damage.
Use trap crops as barriers.
Early removal and destruction of infected plants.
Adjust sowing time to avoid main flights of leaf hoppers.
Spray Malathion (2 ml/litre of water) starting with the appearance of leaf hoppers to control their population.
