Tropical Curly Top Virus (TCTV)
The name “Curly Top” refers to the fact that the leaves curl up at times. The virus is not new, but it was only recently discovered and named after it’s first discovery in Florida in 2009. It had been known since the 1970s, but no one knew what caused it or how to treat it. The virus causes a condition called “curly top” where the leaves curl upwards. It affects all varieties of tomatoes, but most commonly occurs in sweet peppers and eggplants.
TCTV is a non-pathogenic virus which means it does not cause any harm to humans or animals. However, some strains are more virulent than others and can kill plants within days if left untreated.
