Jun 15, 2021 · Curly Top Virus Symptoms. Although symptoms vary among hosts, there are some similar signs of infection. The infected leaves of some host plants, especially tomatoes and peppers, become thick and stiff, rolling upwards. The leaves of beets become twisted or curly. If plants are very young and become infected, they will usually not survive.

Beet Curly Top Virus (BCTV) is taxonomically a Curtovirus in the Geminiviridae family of plant pathogenic viruses. It is vectored, or carried, by the beet leaf- hopper (BLH, Circulifer tenellus) insect. BCTV causes curly top of tomato, a common disease in Utah, and the western U.S. Multiple strains of BCTV have been identified, and molecular charac...
BCTV causes the disease known as curly top of tomato. This virus can infect a wide range of host plants and usually occurs in semiarid areas in western North America, from Canada to Mexico. BLH can transmit the disease to a wide variety of plants, including more than 300 plant species of dicotyledonous plants. Monocotyle- donous hosts (typically gr...
Young plants that are infected with this disease are usually killed. Plants that are infected at a later stage of development may survive, but they will be yellow with stunted growth (Fig. 1). The leaves will become thicker and crisp and will roll upwards as the petioles of the leaf roll downwards, which gives the disease its name (Fig. 2). They wi...
The BLH has a piercing-sucking feeding habit. As the BLHs pierce a plant and feed, they will inject and leave behind virus particles inside the plant. BLH insects carrying the virus need only to feed for one minute on an uninfected plant to transmit the virus. BLHs that have acquired BCTV can transmit the virus for the remainder of their life; howe...
Most of the diagnostic symptomology has already been introduced in previous sections of this fact sheet. However, if a person wishes, they can send samples of suspect plants to the Utah Plant Pest Diagnostic Laboratory (UPPDL). Directions for collecting and submitting samples of plant material to the UPPDL can be found onlineat http://utahpests.usu...
The sporadic nature of BCTV occurrence makes it very difficult to implement practical management strategies for this disease. Research findings, which rely on natural populations of BLH and BCTV in the field, have been very inconsistent (personal communications, Dr. John Damicone, Oklahoma State University). The use of chemicals to control BLH, whe...
