Full Form of PVY

What is PVY?

Potato Virus Y (PVY) is a plant pathogenic virus that primarily infects solanaceous crops, most notably potatoes, tomatoes, and tobacco. It is a member of the Potyvirus genus and is transmitted mainly by aphid vectors in a non-persistent manner, as well as through infected seed tubers. In India, where potato cultivation is a significant agricultural activity, particularly in states like Uttar Pradesh, West Bengal, and Punjab, PVY poses a serious threat to crop yield and quality. Infected plants exhibit symptoms such as leaf mosaic, necrotic spots, and stunted growth, while tubers may develop necrotic rings, making them unmarketable. The virus is managed through the use of certified virus-free seed potatoes, vector control with insecticides, and the cultivation of resistant varieties. PVY is often discussed in agricultural extension programs and plant pathology courses, and it is a key topic in ICAR-JRF, ASRB, and UPSC Agriculture optional exams. Understanding the epidemiology and control of PVY is crucial for ensuring food security and reducing economic losses in Indian potato farming.
