Tomato Curly Top Virus (TCTV) is a plant virus that primarily affects tomato and other members of the Solanaceae family. It is transmitted by certain species of leafhoppers, which feed on infected plants and then spread the virus to healthy ones. Symptoms include stunted growth, curling of leaves, and yellowing, which can significantly reduce crop yields. Control measures for TCTV include using resistant plant varieties, managing leafhopper populations, and practicing crop rotation. Early detection and removal of infected plants can also help prevent the spread of the virus in gardens and agricultural fields.
