Potato Leafroll Virus (PLRV) is a viral disease that primarily affects potato plants. It is transmitted by aphids, which are small sap-sucking insects. Infected plants often show symptoms such as yellowing leaves, stunted growth, and rolling of the leaf edges. These symptoms can lead to reduced yields and poor-quality tubers. Controlling PLRV involves managing aphid populations and using resistant potato varieties. Crop rotation and proper sanitation practices can also help reduce the spread of the virus. Early detection and removal of infected plants are crucial for minimizing the impact of this disease on potato crops.
