# How we can prevent or cure the diseases caused in plants like **Citrus Canker, Rust of Wheat, **and** Yellow Vein Mosaic in Bhindi (Okra)**?

**Citrus canker-** This plant disease is caused by **bacteria.** It occurs in citrus trees/plants such as lemon, lime & orange, etc.

It is transmitted through the **air.**

There is no cure for citrus canker. Prevention is the best option to protect against citrus canker by using copper-based bactericides.

**Rust-** This plant disease is caused by** fungi.** It is transmitted through the air and seeds. It occurs in wheat plants.

A number of fungicides are available such as triazoles and strobilurins for control of these diseases.

**
**

**Yellow Vein Mosaic- **This plant disease is caused by a **virus.** It is transmitted through insects.

It can be cured by sprayings of chemicals like monocrotophos, synthetic pyrethroids, and the application of Chlorpyriphos + neem oil + water.
