Answer 2

Potato mosaic disease is not an air borne disease.

Explanation:

• An air borne disease is a type of disease that is caused by pathogens and transmitted through the air.
• Potato virus is transmitted by aphids by sticking to aphid mouth parts (stylet).
• the virus can be  acquired from the infected plant within seconds, and transmitted to a healthy plant soon.
• It can also be done by  machinery, tools, and damaging plants while walking  through the fields.
• Aphids are uptill now the most efficient means of transmission.
