Kalanchoe plant infected with Kalanchoe Top-Spotting Virus

The Kalanchoe Top-Spotting Virus (KTSV) is a plant pathogen that primarily affects the Kalanchoe species. It is characterized by the appearance of top spotting or chlorotic spots on the leaves of the infected plant. The virus is a member of the Tospovirus genus and is known to be transmitted by thrips.

Symptoms

The most common symptom of KTSV is the appearance of chlorotic or yellowish spots on the top of the leaves. These spots may eventually turn necrotic, leading to the death of the affected tissue. Other symptoms may include stunted growth, leaf curling, and in severe cases, plant death.

Transmission

KTSV is primarily transmitted by thrips, small insects that feed on plant sap. The virus can also be spread through the use of infected plant material in propagation.

Management

Management of KTSV primarily involves the use of resistant plant varieties and the control of thrips populations. Chemical control methods, such as the use of insecticides, may also be used. However, these methods should be used with caution due to the potential for resistance development in the thrips population.

Impact

The impact of KTSV on the Kalanchoe industry can be significant, as the virus can lead to reduced plant quality and yield. This can result in economic losses for growers and nurseries.
