Correct option is C
The correct answer is: C) Phytoplasma
Explanation:
The "Grassy shoot" disease of sugarcane is caused by phytoplasma, a type of bacteria-like organism that lacks a cell wall. Phytoplasmas infect the plant’s phloem tissue, leading to symptoms like stunted growth, yellowing, and the formation of grassy, shoot-like structures. This disease is spread by insect vectors, particularly leafhoppers.

This disease is spread by insect vectors, particularly leafhoppers.
Information Key Points:
The disease causes stunted growth, yellowing, and formation of abnormal shoots.
It is transmitted by leafhoppers.
Management involves controlling insect vectors and using resistant sugarcane varieties.
Additional Information (Other Options):
Fungi: Fungal diseases like red rot or smut affect sugarcane.
Bacteria: Bacterial diseases such as bacterial leaf blight are seen in crops like rice.
Virus: Viruses can cause diseases in sugarcane, but Grassy shoot disease is specifically caused by phytoplasma.
